Italian musical composer, chapel-master at Pistoia, born at Pisa. The time of his death is unknown. He was the most celebrated pupil of Colonna, chapel-master of S. Petronio, at Bologna. He became maestro di cappella at Pistoia about 1712, at Bologna in 1720, and at Pisa in 1736. The works by which Clari distinguished himself preeminently are his vocal duets and trios, with a basso continuo, published between 1740 and 1747. These compositions, which combine graceful melody with contrapuntal learning, were much admired by Cherubini. They appear to have been admired by Handel also, since he did not hesitate to make appropriations from them. Clari composed one opera, Il Savio delirante, produced at Bologna in 1695, and a large quantity of church music, several specimens of which were printed in Novello’s Fitzwilliam Music.
