William Hibbard was a distinguished composer, conductor, violist and teacher. As a composer, he wrote more than forty works, including compositions for mixed chamber ensembles, voice, orchestra and solo instruments. His musical compositions employ strict serial techniques with virtuoso instrumental writing, contrapuntal complexity and unique orchestration. His composition Ménage (1974) for soprano, trumpet and violin was selected by the U.S. jury as one of five American works to be submitted for the 1977 ISCM Festival in Bonn, Germany. In 1988 he was honored with the Distinguished Alumnus Award from the New England Conservatory.

William Hibbard died of an AIDS related illness in San Francisco at the age of 49 on April 5, 1989. [link]
