Violin Sonatas, K. 6–9 (Mozart)

Wolfgang Amadeus Mozart's first four sonatas for keyboard and violin, K. 6–9 are among his earliest works, composed between 1762 and 1764. They encompass several of Mozart's firsts as a composer: for example, his first works incorporating the violin, his first works with more than a single instrument, his first works in more than one movement and his first works in sonata form. In fact, previous to this, all his works had been short solo-pieces for the harpsichord.
