No composer has ever achieved the amazing progression that Haydn has. He invented the string quartet as we know it today, became "the Father of the Symphony," and founded the greatest school in the history of music. His life was one of ceaseless experimentation and invention, of problems surmounted and challenges met. In this book, No. 6 in the Amadeus Press Unlocking the Masters series, David Hurwitz acquaints readers with Haydn's innovative melodic creativity, his revolutionary use of musical form, and important characteristics of his personal style, including his genius for writing in minor keys and creating comedy in his music. In addition to Haydn's principal instrumental works, Hurwitz explores Haydn's vocal music and instrumental masterpieces that fall outside the mainstream. Four appendixes list all of his symphonies, string quartets, piano sonatas, and piano trios. Two Universal Records CDs provide over two and a half hours of music keyed to pieces described in the book.
