sheet music : ウィキペディア英語版
Sheet music is a handwritten or printed form of music notation that uses modern musical symbols. Like its analogs – books, pamphlets, etc. – the medium of sheet music typically is paper (or, in earlier times, parchment), although the access to musical notation in recent years also includes presentation on computer screens. Use of the term "sheet" is intended to differentiate written music from an audio presentation, as in a sound recording, broadcast or live performance, which may involve video as well. In everyday use, "sheet music" (or simply "music") can refer to the print publication of commercial music in conjunction with the release of a new film, show, record album, or other special or popular event which involves music. The first sheet of printed sheet music was made in 1473.Score is a common alternative (and more generic) term for sheet music, and there are several types of scores, as discussed below. ''(Note: the term ''score'' can also refer to theatre music written for a play, musical, opera, ballet, television programme or film; for the last of these, see Film score.)''== Purpose and use ==Sheet music can be used as a record of, a guide to, or a means to perform, a piece of music. Although it does not take the place of the sound of a performed work, sheet music can be studied to create a performance and to elucidate aspects of the music that may not be obvious from mere listening. Authoritative musical information about a piece can be gained by studying the written sketches and early versions of compositions that the composer might have retained, as well as the final autograph score and personal markings on proofs and printed scores.Comprehending sheet music requires a special form of literacy: the ability to read music notation. Nevertheless, an ability to read or write music is not a requirement to compose music. Many composers have been capable of producing music in printed form without the capacity themselves to read or write in musical notation, as long as an amanuensis of some sort is available. Examples include the blind 18th-century composer John Stanley and the 20th-century songwriters Lionel Bart, Irving Berlin and Paul McCartney.The skill of sight reading is the ability of a musician to perform an unfamiliar work of music upon viewing the sheet music for the first time. Sight reading ability is expected of professional musicians and serious amateurs who play classical music and related forms. An even more refined skill is the ability to look at a new piece of music and hear most or all of the sounds (melodies, harmonies, timbres, etc.) in one's head without having to play the piece.With the exception of solo performances, where memorization is expected, classical musicians ordinarily have the sheet music at hand when performing. In jazz music, which is mostly improvised, sheet music – called a lead sheet in this context – is used to give basic indications of melodies, chord changes, and arrangements.Handwritten or printed music is less important in other traditions of musical practice, however. Although much popular music is published in notation of some sort, it is quite common for people to learn a piece by ear. This is also the case in most forms of western folk music, where songs and dances are passed down by oral – and aural – tradition. Music of other cultures, both folk and classical, is often transmitted orally, though some non-western cultures developed their own forms of musical notation and sheet music as well. Although sheet music is often thought of as being a platform for new music and an aid to composition (i.e., the composer ''writes'' the music down), it can also serve as a visual record of music that already exists. Scholars and others have made transcriptions to render western and non-western music in readable form for study, analysis and re-creative performance. This has been done not only with folk or traditional music (e.g., Bartók's volumes of Magyar and Romanian folk music), but also with sound recordings of improvisations by musicians (e.g., jazz piano) and performances that may only partially be based on notation. An exhaustive example of the latter in recent times is the collection ''The Beatles: Complete Scores'' (London: Wise Publications, 1993), which seeks to transcribe into staves and tablature all the songs as recorded by the Beatles in instrumental and vocal detail.==Types==Short score redirects directly here.-->Modern sheet music may come in different formats. If a piece is composed for just one instrument or voice (such as a piece for a solo instrument or for ''a cappella'' solo voice), the whole work may be written or printed as one piece of sheet music. If an instrumental piece is intended to be performed by more than one person, each performer will usually have a separate piece of sheet music, called a part, to play from. This is especially the case in the publication of works requiring more than four or so performers, though invariably a full ''score'' is published as well. The sung parts in a vocal work are not usually issued separately today, although this was historically the case, especially before music printing made sheet music widely available.Sheet music can be issued as individual pieces or works (for example, a popular song or a Beethoven sonata), in collections (for example works by one or several composers), as pieces performed by a given artist, etc.When the separate instrumental and vocal parts of a musical work are printed together, the resulting sheet music is called a ''score''. Conventionally, a score consists of musical notation with each instrumental or vocal part in vertical alignment (meaning that concurrent events in the notation for each part are orthographically arranged). The term ''score'' has also been used to refer to sheet music written for only one performer. The distinction between ''score'' and ''part'' applies when there is more than one part needed for performance.Scores come in various formats, as follows:*A ''full score'' is a large book showing the music of all instruments and voices in a composition lined up in a fixed order. It is large enough for a conductor to be able to read while directing rehearsals and performances.*A ''miniature score'' is like a full score but much reduced in size. It is too small for use in performance, but handy for studying a piece of music, whether it be for a large ensemble or a solo performer. A miniature score may contain some introductory remarks.*A ''study score'' is sometimes the same size as, and often indistinguishable from, a ''miniature score'', except in name. Some study scores are octavo size and are thus somewhere between full and miniature score sizes. A study score, especially when part of an anthology for academic study, may include extra comments about the music and markings for learning purposes.*A ''piano score'' (or ''piano reduction'') is a more or less literal transcription for piano of a piece intended for many performing parts, especially orchestral works; this can include purely instrumental sections within large vocal works (see ''vocal score'' immediately below). Such arrangements are made for either piano solo (two hands) or piano duet (one or two pianos, four hands). Extra small staves are sometimes added at certain points in piano scores for two hands to make the presentation more complete, though it is usually impractical or impossible to include them while playing. As with ''vocal score'' (immediately below), it takes considerable skill to reduce an orchestral score to such smaller forms because the reduction needs to be not only playable on the keyboard but also thorough enough in its presentation of the intended harmonies, textures, figurations, etc. Sometimes markings are included to show which instruments are playing at given points. While piano scores are usually not meant for performance outside of study and pleasure (Liszt's concert transcriptions of Beethoven's symphonies being one group of notable exceptions), ballets get the most practical benefit from piano scores because with one or two pianists they allow unlimited rehearsal before an orchestra is absolutely needed. They can also be used to train beginning conductors. Piano scores of operas do not include separate staves for the vocal parts, but they may add the sung text and stage directions above the music.*A ''vocal score'' (or, more properly, ''piano-vocal score'') is a reduction of the full score of a vocal work (e.g., opera, musical, oratorio, cantata, etc.) to show the vocal parts (solo and choral) on their staves and the orchestral parts in a piano reduction (usually for two hands) underneath the vocal parts; the purely orchestral sections of the score are also reduced for piano. If a portion of the work is ''a cappella'', a piano reduction of the vocal parts is often added to aid in rehearsal (this often is the case with ''a cappella'' religious sheet music). While not meant for performance, vocal scores serve as a convenient way for vocal soloists and choristers to learn the music and rehearse separately from the instrumental ensemble. The vocal score of a musical typically does not include the spoken dialogue, except for cues.**The related but less common ''choral score'' contains the choral parts with no accompaniment.**The comparable ''organ score'' exists as well, usually in association with church music for voices and orchestra, such as arrangements (by later hands) of Handel's ''Messiah''. It is like the piano-vocal score in that it includes staves for the vocal parts and reduces the orchestral parts to be performed by one person. Unlike the vocal score, the organ score is sometimes intended by the arranger to substitute for the orchestra in performance if necessary.**A collection of songs from a given musical is usually printed under the label ''vocal selections''. This is different from the vocal score from the same show in that it does not present the complete music, and the piano accompaniment is usually simplified and includes the melody line.*A ''short score'' is a reduction of a work for many instruments to just a few staves. Rather than composing directly in full score, many composers work out some type of short score while they are composing and later expand the complete orchestration.

Short scores are often not published; they may be more common for some performance venues (e.g., band) than in others.*An ''open score'' is a score of a polyphonic piece showing each voice on a separate staff.

Like its analogs – books, pamphlets, etc. – the medium of sheet music typically is paper (or, in earlier times, parchment), although the access to musical notation in recent years also includes presentation on computer screens. Use of the term "sheet" is intended to differentiate written music from an audio presentation, as in a sound recording, broadcast or live performance, which may involve video as well. In everyday use, "sheet music" (or simply "music") can refer to the print publication of commercial music in conjunction with the release of a new film, show, record album, or other special or popular event which involves music. The first sheet of printed sheet music was made in 1473.'''Score''' is a common alternative (and more generic) term for sheet music, and there are several types of scores, as discussed below. ''(Note: the term ''score'' can also refer to theatre music written for a play, musical, opera, ballet, television programme or film; for the last of these, see Film score.)'''''== Purpose and use ==Sheet music can be used as a record of, a guide to, or a means to perform, a piece of music. Although it does not take the place of the sound of a performed work, sheet music can be studied to create a performance and to elucidate aspects of the music that may not be obvious from mere listening. Authoritative musical information about a piece can be gained by studying the written sketches and early versions of compositions that the composer might have retained, as well as the final autograph score and personal markings on proofs and printed scores.Comprehending sheet music requires a special form of literacy: the ability to read music notation. Nevertheless, an ability to read or write music is not a requirement to compose music. Many composers have been capable of producing music in printed form without the capacity themselves to read or write in musical notation, as long as an amanuensis of some sort is available. Examples include the blind 18th-century composer John Stanley and the 20th-century songwriters Lionel Bart, Irving Berlin and Paul McCartney.The skill of sight reading is the ability of a musician to perform an unfamiliar work of music upon viewing the sheet music for the first time. Sight reading ability is expected of professional musicians and serious amateurs who play classical music and related forms. An even more refined skill is the ability to look at a new piece of music and hear most or all of the sounds (melodies, harmonies, timbres, etc.) in one's head without having to play the piece.With the exception of solo performances, where memorization is expected, classical musicians ordinarily have the sheet music at hand when performing. In jazz music, which is mostly improvised, sheet music – called a lead sheet in this context – is used to give basic indications of melodies, chord changes, and arrangements.Handwritten or printed music is less important in other traditions of musical practice, however. Although much popular music is published in notation of some sort, it is quite common for people to learn a piece by ear. This is also the case in most forms of western folk music, where songs and dances are passed down by oral – and aural – tradition. Music of other cultures, both folk and classical, is often transmitted orally, though some non-western cultures developed their own forms of musical notation and sheet music as well. Although sheet music is often thought of as being a platform for new music and an aid to composition (i.e., the composer ''writes'' the music down), it can also serve as a visual record of music that already exists. Scholars and others have made transcriptions to render western and non-western music in readable form for study, analysis and re-creative performance. This has been done not only with folk or traditional music (e.g., Bartók's volumes of Magyar and Romanian folk music), but also with sound recordings of improvisations by musicians (e.g., jazz piano) and performances that may only partially be based on notation. An exhaustive example of the latter in recent times is the collection ''The Beatles: Complete Scores'' (London: Wise Publications, 1993), which seeks to transcribe into staves and tablature all the songs as recorded by the Beatles in instrumental and vocal detail.==Types==Short score redirects directly here.-->Modern sheet music may come in different formats. If a piece is composed for just one instrument or voice (such as a piece for a solo instrument or for ''a cappella'' solo voice), the whole work may be written or printed as one piece of sheet music. If an instrumental piece is intended to be performed by more than one person, each performer will usually have a separate piece of sheet music, called a part, to play from. This is especially the case in the publication of works requiring more than four or so performers, though invariably a full ''score'' is published as well. The sung parts in a vocal work are not usually issued separately today, although this was historically the case, especially before music printing made sheet music widely available.Sheet music can be issued as individual pieces or works (for example, a popular song or a Beethoven sonata), in collections (for example works by one or several composers), as pieces performed by a given artist, etc.When the separate instrumental and vocal parts of a musical work are printed together, the resulting sheet music is called a ''score''. Conventionally, a score consists of musical notation with each instrumental or vocal part in vertical alignment (meaning that concurrent events in the notation for each part are orthographically arranged). The term ''score'' has also been used to refer to sheet music written for only one performer. The distinction between ''score'' and ''part'' applies when there is more than one part needed for performance.Scores come in various formats, as follows:*A ''full score'' is a large book showing the music of all instruments and voices in a composition lined up in a fixed order. It is large enough for a conductor to be able to read while directing rehearsals and performances.*A ''miniature score'' is like a full score but much reduced in size. It is too small for use in performance, but handy for studying a piece of music, whether it be for a large ensemble or a solo performer. A miniature score may contain some introductory remarks.*A ''study score'' is sometimes the same size as, and often indistinguishable from, a ''miniature score'', except in name. Some study scores are octavo size and are thus somewhere between full and miniature score sizes. A study score, especially when part of an anthology for academic study, may include extra comments about the music and markings for learning purposes.*A ''piano score'' (or ''piano reduction'') is a more or less literal transcription for piano of a piece intended for many performing parts, especially orchestral works; this can include purely instrumental sections within large vocal works (see ''vocal score'' immediately below). Such arrangements are made for either piano solo (two hands) or piano duet (one or two pianos, four hands). Extra small staves are sometimes added at certain points in piano scores for two hands to make the presentation more complete, though it is usually impractical or impossible to include them while playing. As with ''vocal score'' (immediately below), it takes considerable skill to reduce an orchestral score to such smaller forms because the reduction needs to be not only playable on the keyboard but also thorough enough in its presentation of the intended harmonies, textures, figurations, etc. Sometimes markings are included to show which instruments are playing at given points. While piano scores are usually not meant for performance outside of study and pleasure (Liszt's concert transcriptions of Beethoven's symphonies being one group of notable exceptions), ballets get the most practical benefit from piano scores because with one or two pianists they allow unlimited rehearsal before an orchestra is absolutely needed. They can also be used to train beginning conductors. Piano scores of operas do not include separate staves for the vocal parts, but they may add the sung text and stage directions above the music.*A ''vocal score'' (or, more properly, ''piano-vocal score'') is a reduction of the full score of a vocal work (e.g., opera, musical, oratorio, cantata, etc.) to show the vocal parts (solo and choral) on their staves and the orchestral parts in a piano reduction (usually for two hands) underneath the vocal parts; the purely orchestral sections of the score are also reduced for piano. If a portion of the work is ''a cappella'', a piano reduction of the vocal parts is often added to aid in rehearsal (this often is the case with ''a cappella'' religious sheet music). While not meant for performance, vocal scores serve as a convenient way for vocal soloists and choristers to learn the music and rehearse separately from the instrumental ensemble. The vocal score of a musical typically does not include the spoken dialogue, except for cues.**The related but less common ''choral score'' contains the choral parts with no accompaniment.**The comparable ''organ score'' exists as well, usually in association with church music for voices and orchestra, such as arrangements (by later hands) of Handel's ''Messiah''.

==Types==
Modern sheet music may come in different formats. If a piece is composed for just one instrument or voice (such as a piece for a solo instrument or for ''a cappella'' solo voice), the whole work may be written or printed as one piece of sheet music. If an instrumental piece is intended to be performed by more than one person, each performer will usually have a separate piece of sheet music, called a part, to play from. This is especially the case in the publication of works requiring more than four or so performers, though invariably a full ''score'' is published as well.

Sheet music can be issued as individual pieces or works (for example, a popular song or a Beethoven sonata), in collections (for example works by one or several composers), as pieces performed by a given artist, etc.
When the separate instrumental and vocal parts of a musical work are printed together, the resulting sheet music is called a ''score''. Conventionally, a score consists of musical notation with each instrumental or vocal part in vertical alignment (meaning that concurrent events in the notation for each part are orthographically arranged). The term ''score'' has also been used to refer to sheet music written for only one performer. The distinction between ''score'' and ''part'' applies when there is more than one part needed for performance.
Scores come in various formats, as follows:
*A ''full score'' is a large book showing the music of all instruments and voices in a composition lined up in a fixed order. It is large enough for a conductor to be able to read while directing rehearsals and performances.

*A ''vocal score'' (or, more properly, ''piano-vocal score'') is a reduction of the full score of a vocal work (e.g., opera, musical, oratorio, cantata, etc.) to show the vocal parts (solo and choral) on their staves and the orchestral parts in a piano reduction (usually for two hands) underneath the vocal parts; the purely orchestral sections of the score are also reduced for piano.

*A collection of songs from a given musical is usually printed under the label ''vocal selections''. This is different from the vocal score from the same show in that it does not present the complete music, and the piano accompaniment is usually simplified and includes the melody line.
*A ''short score'' is a reduction of a work for many instruments to just a few staves. Rather than composing directly in full score, many composers work out some type of short score while they are composing and later expand the complete orchestration. (An opera, for instance, may be written first in a short score, then in full score, then reduced to a vocal score for rehearsal.) Short scores are often not published; they may be more common for some performance venues (e.g., band) than in others.

It is also sometimes synonymous with full score (which may have more than one part per staff).
*Scores from the Baroque period (1600-1750) are very often in the form of a bass line with figured chords (figured bass) and one or more melody instruments and/or voices
*A ''lead sheet'' specifies only the melody, lyrics and harmony, using one staff with chord symbols placed above and lyrics below. It is commonly used in popular music to capture the essential elements of song without specifying how the song should be arranged or performed.
*A ''chord chart'' or "chart" contains little or no melodic information at all but provides detailed harmonic and rhythmic information.

''(Note: the term ''score'' can also refer to theatre music written for a play, musical, opera, ballet, television programme or film; for the last of these, see Film score.)''== Purpose and use ==Sheet music can be used as a record of, a guide to, or a means to perform, a piece of music. Although it does not take the place of the sound of a performed work, sheet music can be studied to create a performance and to elucidate aspects of the music that may not be obvious from mere listening. Authoritative musical information about a piece can be gained by studying the written sketches and early versions of compositions that the composer might have retained, as well as the final autograph score and personal markings on proofs and printed scores.Comprehending sheet music requires a special form of literacy: the ability to read music notation. Nevertheless, an ability to read or write music is not a requirement to compose music. Many composers have been capable of producing music in printed form without the capacity themselves to read or write in musical notation, as long as an amanuensis of some sort is available. Examples include the blind 18th-century composer John Stanley and the 20th-century songwriters Lionel Bart, Irving Berlin and Paul McCartney.The skill of sight reading is the ability of a musician to perform an unfamiliar work of music upon viewing the sheet music for the first time. Sight reading ability is expected of professional musicians and serious amateurs who play classical music and related forms. An even more refined skill is the ability to look at a new piece of music and hear most or all of the sounds (melodies, harmonies, timbres, etc.) in one's head without having to play the piece.With the exception of solo performances, where memorization is expected, classical musicians ordinarily have the sheet music at hand when performing. In jazz music, which is mostly improvised, sheet music – called a lead sheet in this context – is used to give basic indications of melodies, chord changes, and arrangements.Handwritten or printed music is less important in other traditions of musical practice, however. Although much popular music is published in notation of some sort, it is quite common for people to learn a piece by ear. This is also the case in most forms of western folk music, where songs and dances are passed down by oral – and aural – tradition. Music of other cultures, both folk and classical, is often transmitted orally, though some non-western cultures developed their own forms of musical notation and sheet music as well. Although sheet music is often thought of as being a platform for new music and an aid to composition (i.e., the composer ''writes'' the music down), it can also serve as a visual record of music that already exists. Scholars and others have made transcriptions to render western and non-western music in readable form for study, analysis and re-creative performance. This has been done not only with folk or traditional music (e.g., Bartók's volumes of Magyar and Romanian folk music), but also with sound recordings of improvisations by musicians (e.g., jazz piano) and performances that may only partially be based on notation. An exhaustive example of the latter in recent times is the collection ''The Beatles: Complete Scores'' (London: Wise Publications, 1993), which seeks to transcribe into staves and tablature all the songs as recorded by the Beatles in instrumental and vocal detail.==Types==Short score redirects directly here.-->Modern sheet music may come in different formats. If a piece is composed for just one instrument or voice (such as a piece for a solo instrument or for ''a cappella'' solo voice), the whole work may be written or printed as one piece of sheet music. If an instrumental piece is intended to be performed by more than one person, each performer will usually have a separate piece of sheet music, called a part, to play from. This is especially the case in the publication of works requiring more than four or so performers, though invariably a full ''score'' is published as well. The sung parts in a vocal work are not usually issued separately today, although this was historically the case, especially before music printing made sheet music widely available.Sheet music can be issued as individual pieces or works (for example, a popular song or a Beethoven sonata), in collections (for example works by one or several composers), as pieces performed by a given artist, etc.When the separate instrumental and vocal parts of a musical work are printed together, the resulting sheet music is called a ''score''. Conventionally, a score consists of musical notation with each instrumental or vocal part in vertical alignment (meaning that concurrent events in the notation for each part are orthographically arranged). The term ''score'' has also been used to refer to sheet music written for only one performer. The distinction between ''score'' and ''part'' applies when there is more than one part needed for performance.Scores come in various formats, as follows:*A ''full score'' is a large book showing the music of all instruments and voices in a composition lined up in a fixed order. It is large enough for a conductor to be able to read while directing rehearsals and performances.*A ''miniature score'' is like a full score but much reduced in size. It is too small for use in performance, but handy for studying a piece of music, whether it be for a large ensemble or a solo performer. A miniature score may contain some introductory remarks.*A ''study score'' is sometimes the same size as, and often indistinguishable from, a ''miniature score'', except in name. Some study scores are octavo size and are thus somewhere between full and miniature score sizes. A study score, especially when part of an anthology for academic study, may include extra comments about the music and markings for learning purposes.*A ''piano score'' (or ''piano reduction'') is a more or less literal transcription for piano of a piece intended for many performing parts, especially orchestral works; this can include purely instrumental sections within large vocal works (see ''vocal score'' immediately below). Such arrangements are made for either piano solo (two hands) or piano duet (one or two pianos, four hands). Extra small staves are sometimes added at certain points in piano scores for two hands to make the presentation more complete, though it is usually impractical or impossible to include them while playing. As with ''vocal score'' (immediately below), it takes considerable skill to reduce an orchestral score to such smaller forms because the reduction needs to be not only playable on the keyboard but also thorough enough in its presentation of the intended harmonies, textures, figurations, etc. Sometimes markings are included to show which instruments are playing at given points. While piano scores are usually not meant for performance outside of study and pleasure (Liszt's concert transcriptions of Beethoven's symphonies being one group of notable exceptions), ballets get the most practical benefit from piano scores because with one or two pianists they allow unlimited rehearsal before an orchestra is absolutely needed. They can also be used to train beginning conductors. Piano scores of operas do not include separate staves for the vocal parts, but they may add the sung text and stage directions above the music.*A ''vocal score'' (or, more properly, ''piano-vocal score'') is a reduction of the full score of a vocal work (e.g., opera, musical, oratorio, cantata, etc.) to show the vocal parts (solo and choral) on their staves and the orchestral parts in a piano reduction (usually for two hands) underneath the vocal parts; the purely orchestral sections of the score are also reduced for piano. If a portion of the work is ''a cappella'', a piano reduction of the vocal parts is often added to aid in rehearsal (this often is the case with ''a cappella'' religious sheet music). While not meant for performance, vocal scores serve as a convenient way for vocal soloists and choristers to learn the music and rehearse separately from the instrumental ensemble. The vocal score of a musical typically does not include the spoken dialogue, except for cues.**The related but less common ''choral score'' contains the choral parts with no accompaniment.**The comparable ''organ score'' exists as well, usually in association with church music for voices and orchestra, such as arrangements (by later hands) of Handel's ''Messiah''. It is like the piano-vocal score in that it includes staves for the vocal parts and reduces the orchestral parts to be performed by one person. Unlike the vocal score, the organ score is sometimes intended by the arranger to substitute for the orchestra in performance if necessary.**A collection of songs from a given musical is usually printed under the label ''vocal selections''. This is different from the vocal score from the same show in that it does not present the complete music, and the piano accompaniment is usually simplified and includes the melody line.*A ''short score'' is a reduction of a work for many instruments to just a few staves. Rather than composing directly in full score, many composers work out some type of short score while they are composing and later expand the complete orchestration. (An opera, for instance, may be written first in a short score, then in full score, then reduced to a vocal score for rehearsal.) Short scores are often not published; they may be more common for some performance venues (e.g., band) than in others.*An ''open score'' is a score of a polyphonic piece showing each voice on a separate staff. In Renaissance or Baroque keyboard pieces, open scores of four staves were sometimes used instead of the more modern convention of one staff per hand. It is also sometimes synonymous with full score (which may have more than one part per staff).*Scores from the Baroque period (1600-1750) are very often in the form of a bass line with figured chords (figured bass) and one or more melody instruments and/or voices*A ''lead sheet'' specifies only the melody, lyrics and harmony, using one staff with chord symbols placed above and lyrics below. It is commonly used in popular music to capture the essential elements of song without specifying how the song should be arranged or performed.*A ''chord chart'' or "chart" contains little or no melodic information at all but provides detailed harmonic and rhythmic information. This is the most common kind of written music used by professional session musicians playing jazz or other forms of popular music and is primarily intended for the rhythm section (usually containing piano, guitar, bass and drums).*A ''tablature'' is a special type of musical score – most typically for a solo instrument – which shows ''where'' to play the pitches on the given instrument rather than ''which'' pitches to produce, with rhythm indicated as well. This type of notation, which dates from the late Middle Ages, has been used for keyboard (e.g., organ) and for fretted string instruments (lute, guitar) and is still used for guitar pieces in the realm of popular music.">ウィキペディア(Wikipedia)

Like its analogs – books, pamphlets, etc. – the medium of sheet music typically is paper (or, in earlier times, parchment), although the access to musical notation in recent years also includes presentation on computer screens. Use of the term "sheet" is intended to differentiate written music from an audio presentation, as in a sound recording, broadcast or live performance, which may involve video as well. In everyday use, "sheet music" (or simply "music") can refer to the print publication of commercial music in conjunction with the release of a new film, show, record album, or other special or popular event which involves music. The first sheet of printed sheet music was made in 1473.'''Score''' is a common alternative (and more generic) term for sheet music, and there are several types of scores, as discussed below.

While not meant for performance, vocal scores serve as a convenient way for vocal soloists and choristers to learn the music and rehearse separately from the instrumental ensemble. The vocal score of a musical typically does not include the spoken dialogue, except for cues.**The related but less common ''choral score'' contains the choral parts with no accompaniment.**The comparable ''organ score'' exists as well, usually in association with church music for voices and orchestra, such as arrangements (by later hands) of Handel's ''Messiah''. It is like the piano-vocal score in that it includes staves for the vocal parts and reduces the orchestral parts to be performed by one person. Unlike the vocal score, the organ score is sometimes intended by the arranger to substitute for the orchestra in performance if necessary.**A collection of songs from a given musical is usually printed under the label ''vocal selections''. This is different from the vocal score from the same show in that it does not present the complete music, and the piano accompaniment is usually simplified and includes the melody line.*A ''short score'' is a reduction of a work for many instruments to just a few staves. Rather than composing directly in full score, many composers work out some type of short score while they are composing and later expand the complete orchestration. (An opera, for instance, may be written first in a short score, then in full score, then reduced to a vocal score for rehearsal.) Short scores are often not published; they may be more common for some performance venues (e.g., band) than in others.*An ''open score'' is a score of a polyphonic piece showing each voice on a separate staff. In Renaissance or Baroque keyboard pieces, open scores of four staves were sometimes used instead of the more modern convention of one staff per hand. It is also sometimes synonymous with full score (which may have more than one part per staff).*Scores from the Baroque period (1600-1750) are very often in the form of a bass line with figured chords (figured bass) and one or more melody instruments and/or voices*A ''lead sheet'' specifies only the melody, lyrics and harmony, using one staff with chord symbols placed above and lyrics below. It is commonly used in popular music to capture the essential elements of song without specifying how the song should be arranged or performed.*A ''chord chart'' or "chart" contains little or no melodic information at all but provides detailed harmonic and rhythmic information. This is the most common kind of written music used by professional session musicians playing jazz or other forms of popular music and is primarily intended for the rhythm section (usually containing piano, guitar, bass and drums).*A ''tablature'' is a special type of musical score – most typically for a solo instrument – which shows ''where'' to play the pitches on the given instrument rather than ''which'' pitches to produce, with rhythm indicated as well. This type of notation, which dates from the late Middle Ages, has been used for keyboard (e.g., organ) and for fretted string instruments (lute, guitar) and is still used for guitar pieces in the realm of popular music.">ウィキペディア(Wikipedia)』
Score
is a common alternative (and more generic) term for sheet music, and there are several types of scores, as discussed below. ''(Note: the term ''score'' can also refer to theatre music written for a play, musical, opera, ballet, television programme or film; for the last of these, see Film score.)''== Purpose and use ==Sheet music can be used as a record of, a guide to, or a means to perform, a piece of music. Although it does not take the place of the sound of a performed work, sheet music can be studied to create a performance and to elucidate aspects of the music that may not be obvious from mere listening. Authoritative musical information about a piece can be gained by studying the written sketches and early versions of compositions that the composer might have retained, as well as the final autograph score and personal markings on proofs and printed scores.Comprehending sheet music requires a special form of literacy: the ability to read music notation. Nevertheless, an ability to read or write music is not a requirement to compose music. Many composers have been capable of producing music in printed form without the capacity themselves to read or write in musical notation, as long as an amanuensis of some sort is available. Examples include the blind 18th-century composer John Stanley and the 20th-century songwriters Lionel Bart, Irving Berlin and Paul McCartney.The skill of sight reading is the ability of a musician to perform an unfamiliar work of music upon viewing the sheet music for the first time. Sight reading ability is expected of professional musicians and serious amateurs who play classical music and related forms. An even more refined skill is the ability to look at a new piece of music and hear most or all of the sounds (melodies, harmonies, timbres, etc.) in one's head without having to play the piece.With the exception of solo performances, where memorization is expected, classical musicians ordinarily have the sheet music at hand when performing. In jazz music, which is mostly improvised, sheet music – called a lead sheet in this context – is used to give basic indications of melodies, chord changes, and arrangements.Handwritten or printed music is less important in other traditions of musical practice, however. Although much popular music is published in notation of some sort, it is quite common for people to learn a piece by ear. This is also the case in most forms of western folk music, where songs and dances are passed down by oral – and aural – tradition. Music of other cultures, both folk and classical, is often transmitted orally, though some non-western cultures developed their own forms of musical notation and sheet music as well. Although sheet music is often thought of as being a platform for new music and an aid to composition (i.e., the composer ''writes'' the music down), it can also serve as a visual record of music that already exists. Scholars and others have made transcriptions to render western and non-western music in readable form for study, analysis and re-creative performance. This has been done not only with folk or traditional music (e.g., Bartók's volumes of Magyar and Romanian folk music), but also with sound recordings of improvisations by musicians (e.g., jazz piano) and performances that may only partially be based on notation. An exhaustive example of the latter in recent times is the collection ''The Beatles: Complete Scores'' (London: Wise Publications, 1993), which seeks to transcribe into staves and tablature all the songs as recorded by the Beatles in instrumental and vocal detail.==Types==Short score redirects directly here.-->Modern sheet music may come in different formats. If a piece is composed for just one instrument or voice (such as a piece for a solo instrument or for ''a cappella'' solo voice), the whole work may be written or printed as one piece of sheet music. If an instrumental piece is intended to be performed by more than one person, each performer will usually have a separate piece of sheet music, called a part, to play from. This is especially the case in the publication of works requiring more than four or so performers, though invariably a full ''score'' is published as well. The sung parts in a vocal work are not usually issued separately today, although this was historically the case, especially before music printing made sheet music widely available.Sheet music can be issued as individual pieces or works (for example, a popular song or a Beethoven sonata), in collections (for example works by one or several composers), as pieces performed by a given artist, etc.When the separate instrumental and vocal parts of a musical work are printed together, the resulting sheet music is called a ''score''. Conventionally, a score consists of musical notation with each instrumental or vocal part in vertical alignment (meaning that concurrent events in the notation for each part are orthographically arranged). The term ''score'' has also been used to refer to sheet music written for only one performer. The distinction between ''score'' and ''part'' applies when there is more than one part needed for performance.Scores come in various formats, as follows:*A ''full score'' is a large book showing the music of all instruments and voices in a composition lined up in a fixed order. It is large enough for a conductor to be able to read while directing rehearsals and performances.*A ''miniature score'' is like a full score but much reduced in size. It is too small for use in performance, but handy for studying a piece of music, whether it be for a large ensemble or a solo performer. A miniature score may contain some introductory remarks.*A ''study score'' is sometimes the same size as, and often indistinguishable from, a ''miniature score'', except in name. Some study scores are octavo size and are thus somewhere between full and miniature score sizes. A study score, especially when part of an anthology for academic study, may include extra comments about the music and markings for learning purposes.*A ''piano score'' (or ''piano reduction'') is a more or less literal transcription for piano of a piece intended for many performing parts, especially orchestral works; this can include purely instrumental sections within large vocal works (see ''vocal score'' immediately below). Such arrangements are made for either piano solo (two hands) or piano duet (one or two pianos, four hands). Extra small staves are sometimes added at certain points in piano scores for two hands to make the presentation more complete, though it is usually impractical or impossible to include them while playing. As with ''vocal score'' (immediately below), it takes considerable skill to reduce an orchestral score to such smaller forms because the reduction needs to be not only playable on the keyboard but also thorough enough in its presentation of the intended harmonies, textures, figurations, etc. Sometimes markings are included to show which instruments are playing at given points. While piano scores are usually not meant for performance outside of study and pleasure (Liszt's concert transcriptions of Beethoven's symphonies being one group of notable exceptions), ballets get the most practical benefit from piano scores because with one or two pianists they allow unlimited rehearsal before an orchestra is absolutely needed. They can also be used to train beginning conductors. Piano scores of operas do not include separate staves for the vocal parts, but they may add the sung text and stage directions above the music.*A ''vocal score'' (or, more properly, ''piano-vocal score'') is a reduction of the full score of a vocal work (e.g., opera, musical, oratorio, cantata, etc.) to show the vocal parts (solo and choral) on their staves and the orchestral parts in a piano reduction (usually for two hands) underneath the vocal parts; the purely orchestral sections of the score are also reduced for piano.

Use of the term "sheet" is intended to differentiate written music from an audio presentation, as in a sound recording, broadcast or live performance, which may involve video as well. In everyday use, "sheet music" (or simply "music") can refer to the print publication of commercial music in conjunction with the release of a new film, show, record album, or other special or popular event which involves music.

In everyday use, "sheet music" (or simply "music") can refer to the print publication of commercial music in conjunction with the release of a new film, show, record album, or other special or popular event which involves music. The first sheet of printed sheet music was made in 1473.Score is a common alternative (and more generic) term for sheet music, and there are several types of scores, as discussed below. ''(Note: the term ''score'' can also refer to theatre music written for a play, musical, opera, ballet, television programme or film; for the last of these, see Film score.)''== Purpose and use ==Sheet music can be used as a record of, a guide to, or a means to perform, a piece of music. Although it does not take the place of the sound of a performed work, sheet music can be studied to create a performance and to elucidate aspects of the music that may not be obvious from mere listening. Authoritative musical information about a piece can be gained by studying the written sketches and early versions of compositions that the composer might have retained, as well as the final autograph score and personal markings on proofs and printed scores.Comprehending sheet music requires a special form of literacy: the ability to read music notation. Nevertheless, an ability to read or write music is not a requirement to compose music. Many composers have been capable of producing music in printed form without the capacity themselves to read or write in musical notation, as long as an amanuensis of some sort is available. Examples include the blind 18th-century composer John Stanley and the 20th-century songwriters Lionel Bart, Irving Berlin and Paul McCartney.The skill of sight reading is the ability of a musician to perform an unfamiliar work of music upon viewing the sheet music for the first time. Sight reading ability is expected of professional musicians and serious amateurs who play classical music and related forms. An even more refined skill is the ability to look at a new piece of music and hear most or all of the sounds (melodies, harmonies, timbres, etc.) in one's head without having to play the piece.With the exception of solo performances, where memorization is expected, classical musicians ordinarily have the sheet music at hand when performing. In jazz music, which is mostly improvised, sheet music – called a lead sheet in this context – is used to give basic indications of melodies, chord changes, and arrangements.Handwritten or printed music is less important in other traditions of musical practice, however. Although much popular music is published in notation of some sort, it is quite common for people to learn a piece by ear. This is also the case in most forms of western folk music, where songs and dances are passed down by oral – and aural – tradition. Music of other cultures, both folk and classical, is often transmitted orally, though some non-western cultures developed their own forms of musical notation and sheet music as well. Although sheet music is often thought of as being a platform for new music and an aid to composition (i.e., the composer ''writes'' the music down), it can also serve as a visual record of music that already exists. Scholars and others have made transcriptions to render western and non-western music in readable form for study, analysis and re-creative performance. This has been done not only with folk or traditional music (e.g., Bartók's volumes of Magyar and Romanian folk music), but also with sound recordings of improvisations by musicians (e.g., jazz piano) and performances that may only partially be based on notation. An exhaustive example of the latter in recent times is the collection ''The Beatles: Complete Scores'' (London: Wise Publications, 1993), which seeks to transcribe into staves and tablature all the songs as recorded by the Beatles in instrumental and vocal detail.==Types==Short score redirects directly here.-->Modern sheet music may come in different formats. If a piece is composed for just one instrument or voice (such as a piece for a solo instrument or for ''a cappella'' solo voice), the whole work may be written or printed as one piece of sheet music. If an instrumental piece is intended to be performed by more than one person, each performer will usually have a separate piece of sheet music, called a part, to play from. This is especially the case in the publication of works requiring more than four or so performers, though invariably a full ''score'' is published as well. The sung parts in a vocal work are not usually issued separately today, although this was historically the case, especially before music printing made sheet music widely available.Sheet music can be issued as individual pieces or works (for example, a popular song or a Beethoven sonata), in collections (for example works by one or several composers), as pieces performed by a given artist, etc.When the separate instrumental and vocal parts of a musical work are printed together, the resulting sheet music is called a ''score''. Conventionally, a score consists of musical notation with each instrumental or vocal part in vertical alignment (meaning that concurrent events in the notation for each part are orthographically arranged). The term ''score'' has also been used to refer to sheet music written for only one performer. The distinction between ''score'' and ''part'' applies when there is more than one part needed for performance.Scores come in various formats, as follows:*A ''full score'' is a large book showing the music of all instruments and voices in a composition lined up in a fixed order. It is large enough for a conductor to be able to read while directing rehearsals and performances.*A ''miniature score'' is like a full score but much reduced in size. It is too small for use in performance, but handy for studying a piece of music, whether it be for a large ensemble or a solo performer. A miniature score may contain some introductory remarks.*A ''study score'' is sometimes the same size as, and often indistinguishable from, a ''miniature score'', except in name. Some study scores are octavo size and are thus somewhere between full and miniature score sizes. A study score, especially when part of an anthology for academic study, may include extra comments about the music and markings for learning purposes.*A ''piano score'' (or ''piano reduction'') is a more or less literal transcription for piano of a piece intended for many performing parts, especially orchestral works; this can include purely instrumental sections within large vocal works (see ''vocal score'' immediately below). Such arrangements are made for either piano solo (two hands) or piano duet (one or two pianos, four hands). Extra small staves are sometimes added at certain points in piano scores for two hands to make the presentation more complete, though it is usually impractical or impossible to include them while playing. As with ''vocal score'' (immediately below), it takes considerable skill to reduce an orchestral score to such smaller forms because the reduction needs to be not only playable on the keyboard but also thorough enough in its presentation of the intended harmonies, textures, figurations, etc. Sometimes markings are included to show which instruments are playing at given points. While piano scores are usually not meant for performance outside of study and pleasure (Liszt's concert transcriptions of Beethoven's symphonies being one group of notable exceptions), ballets get the most practical benefit from piano scores because with one or two pianists they allow unlimited rehearsal before an orchestra is absolutely needed. They can also be used to train beginning conductors. Piano scores of operas do not include separate staves for the vocal parts, but they may add the sung text and stage directions above the music.*A ''vocal score'' (or, more properly, ''piano-vocal score'') is a reduction of the full score of a vocal work (e.g., opera, musical, oratorio, cantata, etc.) to show the vocal parts (solo and choral) on their staves and the orchestral parts in a piano reduction (usually for two hands) underneath the vocal parts; the purely orchestral sections of the score are also reduced for piano. If a portion of the work is ''a cappella'', a piano reduction of the vocal parts is often added to aid in rehearsal (this often is the case with ''a cappella'' religious sheet music). While not meant for performance, vocal scores serve as a convenient way for vocal soloists and choristers to learn the music and rehearse separately from the instrumental ensemble. The vocal score of a musical typically does not include the spoken dialogue, except for cues.**The related but less common ''choral score'' contains the choral parts with no accompaniment.**The comparable ''organ score'' exists as well, usually in association with church music for voices and orchestra, such as arrangements (by later hands) of Handel's ''Messiah''. It is like the piano-vocal score in that it includes staves for the vocal parts and reduces the orchestral parts to be performed by one person. Unlike the vocal score, the organ score is sometimes intended by the arranger to substitute for the orchestra in performance if necessary.**A collection of songs from a given musical is usually printed under the label ''vocal selections''. This is different from the vocal score from the same show in that it does not present the complete music, and the piano accompaniment is usually simplified and includes the melody line.*A ''short score'' is a reduction of a work for many instruments to just a few staves. Rather than composing directly in full score, many composers work out some type of short score while they are composing and later expand the complete orchestration. (An opera, for instance, may be written first in a short score, then in full score, then reduced to a vocal score for rehearsal.) Short scores are often not published; they may be more common for some performance venues (e.g., band) than in others.*An ''open score'' is a score of a polyphonic piece showing each voice on a separate staff. In Renaissance or Baroque keyboard pieces, open scores of four staves were sometimes used instead of the more modern convention of one staff per hand. It is also sometimes synonymous with full score (which may have more than one part per staff).*Scores from the Baroque period (1600-1750) are very often in the form of a bass line with figured chords (figured bass) and one or more melody instruments and/or voices*A ''lead sheet'' specifies only the melody, lyrics and harmony, using one staff with chord symbols placed above and lyrics below. It is commonly used in popular music to capture the essential elements of song without specifying how the song should be arranged or performed.*A ''chord chart'' or "chart" contains little or no melodic information at all but provides detailed harmonic and rhythmic information. This is the most common kind of written music used by professional session musicians playing jazz or other forms of popular music and is primarily intended for the rhythm section (usually containing piano, guitar, bass and drums).*A ''tablature'' is a special type of musical score – most typically for a solo instrument – which shows ''where'' to play the pitches on the given instrument rather than ''which'' pitches to produce, with rhythm indicated as well. This type of notation, which dates from the late Middle Ages, has been used for keyboard (e.g., organ) and for fretted string instruments (lute, guitar) and is still used for guitar pieces in the realm of popular music.」の詳細全文を読む
