Composer, performer, guitarist, and educator Larry Polansky has written and arranged over 40 works for a variety of instrumentations. He is a core member of the Frog Peak Music composer's collective, and a widely published music theorist who co-wrote HSML, or Hierarchical Music Specification Language, with Phil Burk and David Rosenboom, as well as other computer software. He taught at Mills College for ten years, then went to Dartmouth, where he teaches electro-acoustic music, is department Chair, and co-director of its electronic music studio. Recordings of some of his compositions appear on the Artifact and Tellus labels; The Theory of Impossible Melody features the use of HMSL. ~ Joslyn Layne, Rovi
