Renowned Brooklyn-born composer (1900–1990) who, more than any other figure, was instrumental in defining the “sound” of American classical music in the first half of the 20th century and in helping American composers to attain a new level of worldwide respectability. Vintage dyeline facsimile of the first page of Copland’s manuscript for the ballet Appalachian Spring, on a 12.5 x 18.75 sheet of imitation vellum, signed later in black felt tip “Aaron Copland, May 12, 1984.” A few marginal creases, wrinkles, and small tears (tape repairs to reverse), otherwise fine condition. Unusual and handsome for display! R&R COA.
