A-flat minor is a minor scale based on A-flat, consisting of the pitches , , , , , , and . For the harmonic minor, the G is raised to G. Its key signature has seven flats (''see below:'' Scales and keys). Its relative major is C-flat major (or, enharmonically, B major), and its parallel major is A-flat major. Its direct enharmonic equivalent is G-sharp minor. Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. Although A-flat minor occurs in modulation in works in other keys, it is only rarely used as the principal key of a piece of music. Some well-known uses of the key in classical and romantic piano music include: * The Funeral March in Ludwig van Beethoven's Piano Sonata No. 12, Op. 26. * An early section of the last movement of Beethoven's Piano Sonata No. 31, Op. 110 (although the key signature of this section uses only 6 flats, not 7). * The Adagio of Friedrich Kalkbrenner's Piano Concerto No. 4, Op. 127, although it is written with a four-flat key signature and uses accidentals to indicate the minor mode. * The first piece "Aime-moi" ("Love me") from Charles-Valentin Alkan's ''Trois morceaux dans le genre pathétique'' * Johannes Brahms's Fugue for organ (c. 1857). * Max Bruch's Concerto for Two Pianos and Orchestra, Op. 88a (although at least one two-piano transcription of this uses a 6-flat signature, similarly to the Op. 110 Beethoven example). * The Evocación from Book I of Isaac Albéniz's ''Iberia.'' * Leoš Janáček uses it for his Violin Sonata and the organ solo of his ''Glagolitic Mass.'' * The opening of Igor Stravinsky's ''The Firebird''. * Moritz Moszkowski used it for his piano etude, Op. 72 No. 13. * Franz Liszt's original version of "La campanella" from ''Grandes études de Paganini'', which was subsequently rewritten in G-sharp minor. * In Gustav Mahler's Ninth Symphony, there is a particularly aggressive restatement of the introduction of the third movement in A-flat minor.〔Mahler, Gustav. ''Symphony No. 9 in Full Score'', Dover, ISBN 0-486-27492-6 (1993), pp. 116-119.〕 It is also used in Frederick Loewe's score to the 1956 musical play ''My Fair Lady''; the Second Servants' Chorus is set in A-flat minor (the preceding and following choruses being a semitone lower and higher respectively). More often, pieces in a minor mode that have A-flat's pitch as tonic are notated in the enharmonic key, G-sharp minor, because of G-sharp's appreciably simpler key signature. As a result, only works expressly notated as such may reasonably be considered to be in A-flat minor. In some scores, the A minor key signature in the bass clef is written with the flat for the F on the second line from the top. ==Scales and keys== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「A-flat minor」の詳細全文を読む スポンサード リンク
