A 'Tone Poem' is a story told by musical instruments and could also be called 'sound pictures' - describing things, places, persons and events. The most well known tone poems of the American West are the 'Grand Canyon Suite' (1931) by Ferde Grofe and Aaron Copland's 'Billy the Kid' (1938) and 'Rodeo' (1942). Grofe lived near the Grand Canyon for a period of time and was inspired by its magnificence, and Copland was fascinated with the story of the western character - Billy the Kid.
