This article presents a complete list of compositions by American composer Morton Feldman, organized by instrumentation. There are about 184 compositions in total.[clarification needed] Within each category, the works are arranged chronologically by year of composition. Note that works for piano solo (or, for example, cello solo) are in the solo instrumental category, however, works for 2 or more pianos (2 or more cellos, etc.) are in the chamber category.
Many pieces by Feldman are titled after the instruments used: for example, Two Pieces for Clarinet and String Quartet is scored precisely for clarinet and string quartet. In cases like this, instrumentation is not given separately. Works with titles in square brackets are unpublished works, left untitled by the composer; these are commonly referred to using the generic title "Composition" (with the exception of a few early works).
