“Ever heard of an adapted viola? What about a chromalodeon? They’re all instruments invented by avante-garde composer Harry Partch. Partch was a California native who threw out traditional keys and patterns in favor of strange and complex 43+ note microtonal scales. Off-Ramp’s Kevin Ferguson headed to a rehearsal studio on Mount Washington to talk to John Schneider, a music professor and a member of Partch, a musical tribute to the late composer. In this video, John Schneider performs “The Letter” on a custom made harmonic canon.” Source: 89.3 KPCC, Southern California Public Radio.
