Alto flute multiphonic example by soundandmusic published on 2010-10-07T10:39:08Z Multiphonics: There is a wide range of available multiphonics on the flute, and the advent of the Kingma system flute, with its greater venting, has increased the possibilities exponentially, especially for alto and bass. Standard alto and bass flutes have close-holed key-work, so the multiphonic possibilities are greatly reduced in comparison with an open-holed C flute. The important thing to bear in mind when writing multiphonics is that they will generally only work within a small dynamic range. As a general rule, the closer together the two notes are in pitch, the quieter they will be, and conversely, the wider the intervallic range, the louder the dynamic. Some more stable multiphonics might work over a range of dynamics, but this very rarely covers the whole dynamic range of the instrument. A list of multiphonics can be found in the resources mentioned below. It should be noted that due to the increase in tube size, alto and bass flutes respond differently to certain fingerings than C flutes, and pitches may be altered or non-existent. This is particularly true of notes in the high register, since the bigger instruments have fewer high harmonics in the sound.
