Last week our woodwind shop did some pad work on a lesser seen member of the woodwind family: an alto flute. Alto flutes have a lower register than a “standard” flute, pitched a fourth below a “C” flute. This lower pitch is made possible by a wider bore (the “tube” that is the flute body is a larger diameter) and a longer overall body. The last four photos show the sections of the alto flute next to their corresponding sections of a standard “C” flute.
Alto flutes were largely standardized by the noted German woodwind designer Theobald Böhm (1794-1881) who introduced a more comfortable and compact key system to the instrument to make it more comfortable to play and increased the instrument’s popularity.
Many composers including Ravel, Prokofiev, Shostakovich, and Holst wrote for alto flute. A great listening example is in Holst’s “The Planets” where the instrument is featured in “Neptune, The Mystic”. Give it a listen!
