A composer who combined jazz and classical music into a new sound in the 1920s was George Gershwin (1989-1937). He was american pianist and composer. He studied classical music, but later he got interested in popular music genres, and used to compose operas, film music, concerts and symphonies. Gershwin strongly influenced many musicians, and he is considered to be a first exponent of the symphonic jazz genre. His most famous works are orchestral compositions Rhapsody in blue (1924) and American in Paris (1928), as well as opera Porgy and Bess (1935).</span>
