As a music librarian for Yale, Perlis worked with The
Charles Ives Papers. In 1968, she had an opportunity to interview the elderly
Julian Myrick, Ives’ insurance business partner. Recognizing the profound usefulness of recorded memories such as these, Perlis began collecting interviews with other acquaintances of
Charles Ives. These amounted to sixty-two tapes and transcripts. In 1975, the book won the
American Musicological Society's Otto Kinkeldey Award, their most prestigious book award. Perlis was the first female recipient, and this was the first time the award was given for an American musical subject. The book was also honored with the Connecticut Book Publishers Award. While conducting her Ives research, Perlis recognized the value of oral history to document musical figures, and she founded the
Oral History of American Music (formerly Oral History, American Music) in 1969. Perlis and composer
Aaron Copland first became friends while working on the Ives project. Copland later wrote the preface for her book,
Charles Ives Remembered. As the Ives project finished, Perlis focused on Copland as her new subject. From 1975-’76, she conducted many hours of interviews with Copland and those closest to him. Finally in 1984 and 1989, their efforts culminated in the autobiographies,
Copland: 1900 through 1942 and
Copland: Since 1943, co-authored by Perlis.
Oral History of American Music (OHAM) holds over 2,200 interviews and transcripts and is a special collection within
Yale University’s Irving S. Gilmore Music Library. The core unit, Major Figures in American Music, includes interviews with composers, classical performers, and jazz musicians. OHAM also holds projects on Ives,
Paul Hindemith,
Steinway & Sons, and
Duke Ellington, video interviews with Yale graduate composers, and acquisitions. In 2005, Perlis released a new book,
Composers’ Voices From Ives to Ellington, which was co-written with
Libby Van Cleve. The book celebrates 20th century composers and includes two CDs of interview material. Perlis announced her retirement from
Oral History of American Music in 2010. She died at her home in
Weston, Connecticut, on July 4, 2019, at the age of 91, following an illness. ==Media production==
