The alto flute is a type of Western concert flute, a musical instrument in the woodwind family. It is the next extension downward of the C flute after the flûte d'amour. It is characterized by its distinct, mellow tone in the lower portion of its range. It is a transposing instrument in G and, like the piccolo and bass flute, uses the same fingerings as the C flute. The tube of the alto flute is considerably thicker and longer than a C flute and requires more breath from the player.〔(Finding Your Flute (How to Choose, Rent, Buy a New or Used Flute) )〕 This gives it a greater dynamic presence in the bottom octave and a half of its range. It was the favourite flute variety of Theobald Boehm, who perfected its design, and is pitched in the key of G (sounding a perfect fourth lower than written). 〔 〕 Its range is from G3 (the G below middle C) to G6 (4 ledger lines above the treble clef staff) plus an altissimo register stretching to D7. The headjoint may be straight or curved. British music that uses this instrument often refers to it as a bass flute, which can be confusing since there is a distinct instrument known by that name.〔 This naming confusion originated in the fact that the modern flute in C is pitched in the same range as the Renaissance tenor flute, therefore a lower pitched instrument would be called a bass.〔 http://www.oldflutes.com/renai.htm 〕 ==Headjoint shape== Pictured above is the 'curved head' version, frequently preferred by smaller players because it requires less of a stretch for the arms, and makes the instrument feel lighter by moving the center of gravity nearer to the player. However, the straight version is more commonly used for better overall intonation.〔(Phyllis Louke - Article: Getting Started Playing Alto, Bass and Contrabass Flutes )〕 The embouchure for alto flute is similar to that for C flute, but in proportion to the size of the instrument. Hence the embouchure-hole sits lower on the lower lip, and the lip-aperture is wider. 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「alto flute」の詳細全文を読む スポンサード リンク
