Paul Hindemith was a German composer of the Twentieth century. He became a primary advocate of the Neue Sachlichkeit form of music. The musical experience of Hindemith had been very complicated. He was most notable for his work as a musician, but early in his work as a performer, he eventually used his chamber musical skills for publicity and public relations in the Donaueschingen Festival. However, he still made sure he had tome to compose. A great deal of his music was composed during his performances between 1917 and 1924. He also started teaching at the University of Music in Berlin while still working for the Festival.
