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.” (Marc Medwin, 2015)

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) has been 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). She has contributed chapters to Perspectives on the Performance of French Piano Music and Messiaen Perspectives (both Ashgate). She guest edited the issue of Contemporary Music Review “Performers on Performance” and has contributed articles to the Journal of the Institute for Studies in American Music, Journal of Hand Therapy, Perspectives of New Music, Current Musicology, Ecological Psychology, and Music and Medicine.
