. . . “soli” is expanding the presumed limits of an instrument with the help of a personal musical language is central to my approach to the instrument. The focal point is the playful method of improvising with this vocabulary. The performing techniques (circular breathing, simultaneous singing and playing, key tapping rhythms, extremely fast passages which evoke a quasi polyphony, enharmonic changes, multiphonics, double tonguing, overblowing…) permit the creation of acoustical phenomena which, as with an illusionist, suggest other levels…. This occurs here without the aid of electronic devices or overdubs.
