American avant-garde composer associated with John Cage (Cage, John).

Feldman studied composition with Wallingford Riegger (Riegger, Wallingford) and Stefan Wolpe. In the 1950s, much more influenced by Abstract Expressionist painters than by other composers, he began using a method of graphic notation that included such devices as indicating the length of a note by a horizontal line drawn in the score, or specifying the number of notes to be played in a segment by a number. Pitch and rhythm were indicated in very general terms, the main interest being in the manipulation of contrasting densities and timbres, usually played very softly. After further experiments in the 1960s, he returned to conventional notation in his compositions. Feldman's music was typically minimalist in its simplicity, austerity, and meditative quality. He explored original timbres by means of slowly paced repetitions of unrelated, soft sounds, creating a hushed and ethereal mood with them.
