Aaron Copland is one of the most celebrated composers of the 20th century. While his work reflects great diversity—including 12-tone and other serial pieces—he is perhaps best known as a composer of “American” music. Pieces such as Appalachian Spring, Rodeo, and Billy the Kid, are striking harmonic tapestries woven with rhythms and melodies rooted in American folk songs. Copland was also a student of the incomparable Nadia Boulanger.
A further Blackwing 602 connection is that he composed the score for Of Mice and Men, written by another famous Blackwing user, John Steinbeck.
