Voix Instrumentalisée for Bass Clarinet (Solo) by Vinko Globokar. C.F. Peters, 1975, 5 pages. Vinko Globokar (1934-) is a French avant-garde composer and trombonist of Slovenian descent. His work is noted for its use of unconventional and extended techniques. In Voix Instrumentalisée, Globokar asks the bass clarinet player to learn a couple of new techniques to play the instrument. The mouthpiece is removed and not used at all. Instead, the performer has to sing, speak and blow into the bass clarinet while changing the fingering and adding special effects with the voice and the keyclick sounds. (C1954)
