Tomaso Giovanni Albinoni ( 1671-1751) was a Venetian Baroque composer. While famous in his day as an opera composer, he is mainly remembered today for his instrumental music, such as the concertos, some of which are regularly recorded. Born in Venice, he studied violin and singing. Relatively little is known about his life, especially considering his contemporary stature as a composer, and the comparatively well-documented period in which he lived. In 1694 he dedicated his Opus 1 to the fellow-Venetian, Cardinal Pietro Ottoboni (grand-nephew of Pope Alexander VIII); Ottoboni was an important patron in Rome of other composers, such as Arcangelo Corelli. Albinoni was possibly employed in 1700 as a violinist to Charles IV, Duke of Mantua, to whom he dedicated his Opus 2 collection of instrumental pieces. In 1701 he wrote his hugely popular suites Opus 3, and dedicated that collection to Cosimo III de' Medici, Grand Duke of Tuscany.
