Upon her 1993 recital debut, Marilyn Nonken was heralded as "a determined protector of important music" (New York Times). Since then, she has been recognized as "one of the greatest interpreters of new music" (American Record Guide). Writes Fanfare: “Her voicings are exquisite, her pedaling throughout is a model to be studied, and, when necessary, her virtuosity is equaled only by the insight and passion with which every piece is imbued.” (2015) Since 2006, she has been Director of Piano Studies at NYU's Steinhardt School, where she is Professor of Music.

A student of David Burge at the Eastman School, Marilyn Nonken received a Ph.D. in musicology from Columbia University. Her monograph The Spectral Piano (Cambridge University Press, 2015) was received as “a screaming success …. Few books can boast as much, and it is gratifying to encounter an international concert performer who can make so engaging a discourse around her core repertoire." (Bob Gilmore, Tempo). Identity and Diversity in New Music: The New Complexities (Routledge) was published in 2019. She has written chapters for Perspectives on the Performance of French Piano Music, Messiaen Perspectives, Messiaen in Context and Oxford Handbook of Spectral Music; served as a guest editor for Contemporary Music Review; and contributed articles to numerous journals.
A Steinway artist, Marilyn Nonken has recorded for New World, Mode, Lovely Music, Albany, Metier, Divine Art, Hanging Bell, Harrison House, Innova, CRI, BMOP Sound, New Focus, Kairos, Tzadik, and Bridge.
