Ezra Sims

Ezra Sims (1928-2015) was an American composer, born in Birmingham, Alabama, and active in Boston, known for microtonal music. He wrote in asymmetrical modes of 18 pitches taken from a division of the octave into 72 notes, and the notation he devised for this tuning is used by other microtonal composers in Boston. Sims studied with Darius Milhaud, held a Guggenheim fellowship, and for several years made tape pieces for dancers. He co-founded the Dinosaur Annex Music Ensemble and was its president from 1977 to 1981.
