Show 22 Another composer/performer who has also created an important catalog of extended techniques for the voice is the English composer Trevor Wishart (b. 1946). Wishart has taken the relationship between the voice and electronic music that was explored by pioneers such as Stockhausen and Berio, and delved deeper into the acoustical properties of the voice, allowing him greater flexibility in the electronic realm. Wishart writes primarily digital audio media with extensions of the voice serving as the main source material. He has several publications, including On Sonic Art (1996), where he demonstrates some of the philosophies and tools he uses in the creation of his digital audio media. On Sonic Art also includes a chapter called "The Human Repertoire" which catalogs all sounds human. In addition to vocal sounds, Wishart includes sounds that can be made with the hands when combined with the voice. His discussion starts with vocal oscillators and filters and then proceeds through various vocal effects. Wishart is methodical in his exploration of the sounds that a human, not just a human voice can make. On Sonic Art has an accompanying CD where the described vocal sounds are demonstrated. Unlike the Lexicon, Wishar: puts more focus on nonlaryngeal oscillators and includes a section on combining various vocal sounds. Wishart is interested in EVT's as they can be used in connection with electronic music, while the Lexicon is more of a tool for composition of purely vocal pieces. |
