(b Pistoia, 22 Oct. 1737; d St Petersburg, 16 Aug. 1799). Italian theorist and composer. After studying with G. A. Perti in Bologna he went to Moscow in 1758, later becoming court maestro di cappella at St Petersburg. In 1762 he was also appointed maestro to the Italian opera company there. He returned to Bologna with a pension in 1769, Galuppi having taken over much of his work in Russia, but was invited back to St Petersburg in 1798. His compositions, which include a Requiem for the Russian Empress Elizabeth, are less important than his sometimes controversial theoretical writings on keyboard accompaniment and the teaching of singing.
