i. Allegro di molto
ii. Andante grazioso 

Sonata in A was inspired by Joseph Schuster’s piano and violin duets, which Mozart first played whilst looking for jobs in Mannheim, Germany. The sonata is made of 2 movements. The first is in sonata form, which follows the structure of introducing a musical idea or ideas, exploring it and then returning to the main themes at the end. It is one of Mozart’s most joyous melodies of all his violin sonatas. The second movement is a theme–and–variation form and completely contrasts with the tone of the first. It has a slower tempo and a much more subdued melody and is followed by six variations on the main theme. Typical of theme-and-variation pieces of the time, the penultimate variation is very stark, and in a minor mode. The set ends with an up-tempo dance and is the only piece of the lot that is in triple metre instead of duple.
