My good friend and music teacher, Ken, passed on these links to Harry Partch websites. These are well worth looking at for more information on the composer and his music.
First we have Corporeal Meadows, the official website of the Harry Partch Foundation.
Then, the Harry Partch Information Center, maintained by Newband, an Artist Ensemble in Residence in the Department of Music, McEachern Music Building, Montclair State University, New Jersey.
Finally, a webpage on Harry Partch's instruments, from the American Public Media's "American Mavericks" series, maintained by the San Francisco Symphony Orchestra. This is especially fascinating as you can use this to sound out both the pitches and timbres from Partch's extraordinary collection of self-designed instruments. For example, here is a link to Partch's bass marimba. This one is a lot of fun!
