Book excerpt: Franz Joseph Haydn (1732 1809) has been called the father of the symphony and the string quartet. A friend of Mozart and a teacher of Beethoven, "Papa" Haydn composed an amazing variety of music -- symphonies, string quartets, concerti, masses, operas, oratorios, keyboard works -- and his prolific output celebrates both the heights and depths of life. In this fascinating book Calvin Stapert combines his skills as a biographer and a musicologist to recount Haydn's steady rise from humble origins to true musical greatness. Unlike other biographers, Stapert argues that Haydn's work was a product of his devout Catholic faith, even though he worked mainly as a court musician and the bulk of his output was in popular genres. In addition to telling Haydn's life story, Stapert includes accessible listening guides to The Creation and portions of other well-known works to help Haydn listeners more fully appreciate the brilliance behind his music.
