Felix Salzer (June 13, 1904 – August 12, 1986) was an Austrian-American music theorist, musicologist and pedagogue.
He studied musicology with Guido Adler at the University of Vienna, finishing his Ph.D. in 1926 with a dissertation on sonata form in the works of Franz Schubert.
While teaching at Mannes, Salzer and Schacter went on to co-author the seminal music theory book: "Counterpoint in Composition."
Some of the specific refinements Salzer made to Schenkerian theory involve aspects of voice leading, and the differentiation of chords into structural versus contrapuntal categories.
Salzer's works include Structural Hearing (1952 and 1962), Counterpoint in Composition: The Study of Voice Leading (with Carl Schachter, 1969), and the periodical The Music Forum (initiated 1967).
