Hierarchical Music Specification Language
HMSL

    (HMSL) A programming language for
   experimental music composition and performance.  It is a set
   of object-oriented extensions to Forth.  (Its near-total
   unintelligibility to people unfamiliar with Forth has led
   some to expand "HMSL" as "Her Majesty's Secret Language".)

   Phil Burk (who also later developed pForth), Larry Polansky,
   and David Rosenboom started developing HMSL in 1980 while
   working at the <Mills College Center for Contemporary Music>.  As of
   June 1998, development is ongoing.
