One of the most prominent Italian musicians of the 17th Century, Giovanni Legrenzi was the teacher of Vivaldi and Caldara, among others. Legrenzi’s sonatas are considered the foundation of the modern sonata format. Legrenzi’s cantatas were extremely important and made enormous influence on A. Scarlatti’s compositions. Legrenzi wrote works for virtually every instrument and voice, he composed operas, cantatas and instrumental music. In 1685, Legrenzi was appointed maestro di cappella at San Marco and paid most of his attention to sacred music.
