Lucid and deeply erudite, David Schroeder's fine study of Joseph Haydn's symphonic writing reveals the gradual evolution of the composer's musical thought processes. Haydn claimed that through working in isolation from mainstream musical influences he was forced to be original, but the truth is shown to be slightly different. He possessed a substantial library, knew the music of his contemporaries, was well read and keenly aware of contemporary philosophical and social developments. In common with many musicians of his time he regarded vocal music as the most important genre, instrumental music taking a second place, but one of Haydn's most significant achievements was to develop in the symphony an instrumental form that was to become the vehicle for some of the most profound music ever written. He believed music to have value as a moral force that could be communicated to his audiences and be of benefit in their lives. In this he is shown to be a truly great figure of the Enlightenment. An excellent book, highly recommended.
