During her career, DeGaetani appeared with most of the major English and American orchestras, usually in works by contemporary composers. Her regular appearances with the Contemporary Chamber Ensemble evoked many fine performances, including Schoenberg's Pierrot Lunaire. She also appeared with the Chamber Music Society of Lincoln Center and with Speculum Musicae.
Always an intelligent performer, DeGaetani had a voice with great expressive range; she was one of the rare singers of contemporary music to garner not only critical praise, but also popularity with the general public. In 1973, she was appointed a professor of voice at the Eastman School of Music in Rochester, NY, where she remained on the faculty until her death. Among her students, the most outstanding is the soprano Dawn Upshaw. During the summers, she also taught at the Aspen Music Festival. She often gave master classes in conjunction with her recital tours in order to pass her love of contemporary music on to the next generation. ~ Richard LeSueur, Rovi
