Studying In Vienna

He did not immediately set out to establish himself as a composer, but rather devoted himself to study and performance. Working under Haydn's direction, he sought to master counterpoint. He also studied violin under Ignaz Schuppanzigh. Early in this period, he also began receiving occasional instruction from Antonio Salieri, primarily in Italian vocal composition style; this relationship persisted until at least 1802, and possibly as late as 1809.
