Aaron Rabushka queries: >What is the practical range of the flexatone? I know it has an elaborate >obbligato in the Khachaturian piano concerto, and I've also heard it in >some parts (probably less well defined) of works by Eaton and Penderecki. Also in Honegger somwhere, and nowadays (past it's 'popular novelty' phase) mostly in film music. Kinda like a musical saw. The range? I think it's essentially a monotonal instrument, complicated by the fact that most of what it does is make a weird, eerie vibrato-like noise. I don't know if they come in different pitches, but I don't think you can alter the pitch much beyond the vibrato. Or were you asking the range of the vibrato? Couldn't say. Bob K.
