Johann Joseph Fux (pronounced ) (1660 – February 13, 1741) was an Austrian composer, music theorist and pedagogue of the late Baroque era. He is most famous as the author of Gradus ad Parnassum, a treatise on counterpoint, which has become the single most influential book on the Palestrina style of Renaissance polyphony. Almost all modern courses on Renaissance counterpoint, a mainstay of college music curricula, are indebted in some degree to this work by Fux. Life Fux was born to a peasant family in Hirtenfeld in Styria. Relatively little is known about his early life, but likely he went to nearby Graz for music lessons. In 1680 he was accepted at the Jesuit university there, where his musical talent became apparent; and he was organist at St Moritz until 1688. Sometime during this period he must have made a trip to Italy, as evidenced by the strong influence of Corelli and Bolognese composers on his work of the time.
