Earle Brown (December 26, 1926 – July 2, 2002) was an American composer who established his own formal and notational systems. Brown was the creator of open form, a style of musical construction that has influenced many composers since—notably the downtown New York scene of the 1980s and generations of younger composers.

Among his most famous works are December 1952, an entirely graphic score, and the open form pieces Available Forms I & II, Centering, and Cross Sections and Color Fields.
