Aaron Copland, American composer, used cowboy songs to highlight
the frontier themes in his ballets “Billy the Kid” and “Rodeo”. Since Copland’s
most important ballets are based on American folk material (Billy the Kid
(1938), Rodeo (1942), and Appalachian Spring (1944)), he used cowboy songs and
American folk songs to contribute to the main themes.
They made music out of nature and the sounds of tree wood banging on another stick of tree wood. Thats how they did music in the past now its digitally.
