Born in Vienna. Italian priest, violinist and composer who, for many years, taught music in a girls' orphanage in Venice. He wrote operas, church music, symphonies and concertos for strings, or strings and wind, mostly in a light and brilliant style.

His string concertos exploit the technical possibilities of instruments with great skill and imagination, and are much performed today.  He is especially important for concertos, of which he wrote nearly four hundred, and many important vocal works.
