Vivaldi is known mainly for composing instrumental concertos, especially for the violin, as well as sacred choral works and over 40 operas. His best known work is a series of violin concertos known as The Four Seasons. Many of his compositions were written for the female music ensemble of the Ospedale della Pietà, a home for abandoned children where Vivaldi worked from 1703 to 1715 and from 1723 to 1740. Vivaldi also had some success with stagings of his operas in Venice, Mantua and Vienna. After meeting the Emperor Charles VI, Vivaldi moved to Vienna hoping for preferment. The Emperor died soon after Vivaldi's arrival, and the composer died a pauper, without a steady source of income.
