After attending Mills College for a year, she moved to New York, where she studied privately with composers Frank La Forge and Clarence Dickinson, both of whom were known for their art songs.

[1] In demand as both a pianist and a composer, she was a soloist twice with the Los Angeles Philharmonic and made several recordings as a collaborator with various singers.

Warren spent most of her composition career in Los Angeles, which was considered an unusual choice at the time, given that New York was thought to be the center of new American music.

Remick Warren's intermission chimes, commissioned by Dorothy Chandler for the Los Angeles Music Center which opened in 1964, have been heard there ever since.

[2] Her composition instructors included Olga Steeb, Paolo Gallico, Frank La Forge, Clarence Dickinson, and Nadia Boulanger.
