Extended Voices, for voices with Moog Synthesizer and Buchla Associates Electronic Modular System

In Ichiyanagi's Extended Voices, singers use musical instruments, such as slide whistles, to extend the range of their voices. At the same time, electronic instruments transform the voices in terms of timbre, range, and dynamics. The written score consists mostly of sustained sounds and glissandos of varying lengths and speeds. The development of the material depends upon a cueing arrangement that instructs the singer to perform in relation to sounds he hears another performer make. Extended Voices also includes a pre-recorded tape, composed of purely electronically produced sounds, that functions as complementary or accompaniment material.
