In his lifetime Joseph Haydn enjoyed huge popularity throughout Europe. As a composer of symphonies, quartets, masses, and oratorios he was readily acknowledged by Mozart, Beethoven, and others as a commanding figure. He is one of the founding fathers of classical music, yet only in the last 50 years have his works become available in reliable editions, and much biographical detail has come to light at the same time. Meanwhile, his music is more popular today than it has been atany time since his death. This detailed, scholarly, and lively Companion draws together a wealth of biographical detail and expert analysis for the the first time in an accessible, engaging format. It covers Haydn's life and times, and his music, including its performance and reception.The Companion focuses on the period of Haydn's life (1732-1809), but extends forward to the end of the 20th century, to cover Haydn's reputation in the 19th century, attempts at complete editions, and modern scholarship.
