CHAPTER 5 - Etudes & Exercises
Etude 4 contains multiphonics of three or more voices. In order to connect these in a legato fashion, the player must anticipate, through accurate aural and tactile memory, the changes in embouchure pressure, voicing, and finger motion. Some multiphonics need a tighter embouchure to coax all the voices to speak together (measure 9). Some of the multiphonic motion in this etude occurs among fingerings with the same left hand fingering (m.1; 2-3). Fulcrum exercises can help the player balance these sounds. Strive to balance the pitches of the multiphonics while maintaining the smoothest possible legato.

Other progressions involve slight left hand finger movements (m.5) – fulcrum studies also help here.
Exercise #58 (click on music for mp3)
Some multiphonics with greater resistance need to be isolated and practiced in order to attack all the pitches together (m.11 last beat; m.7 first beat).
Exercise #59 (click on music for mp3)
The progression in measures 13-7 also demonstrates the different resistance between conventional pitches and multiphonics that include these pitches. A looser embouchure, along with an attempt to match pitches will help the voices of the multiphonics to speak and sustain equally.
