it is unusual for a great musician to begin studying music properly at the age of 18. however, he was old enough to realize that he had a lot to learn. he studied counterpoint and was influenced by the way classical composers had shaped their music. beethoven especially was an inspiration for him. one of his best-known works is the "concerto for double string orchestra" (1938-1939). it shows his love of folk music as well as interest in english music of the renaissance. this music is exciting because of its beats, which keep changing, and its dance-like character.
