Alfred Whitford (Fred) Lerdahl (born March 10, 1943) is an American music theorist and composer.

Lerdahl's students include composers Christopher Buchenholz, Zosha Di Castri, R.

Young; and music theorists Elizabeth Margulis and David Temperley.

[3] Lerdahl's influences include the German classics, Sibelius, Schoenberg, Bartók, Stravinsky, Carter, Messiaen, and Ligeti.

[4] In Fanfare, Robert Carl wrote: "Lerdahl is a profoundly musical composer, engaged in all his work in a rigorous and respectful dialogue with tradition, eager to imbue his pieces with the maximum of both information and clarity.

Unlike Debussy's La mer, whose deep-sea swells it recalls only fleetingly, it has no moments of repose.
