The score of Sonata III in B flat is set out on three staves marked Violino; Hautbois; Basson. However, figures appear below the bassoon stave towards the end of the first movement, and also at the opening bars of the final movement – an indication that an instrument capable of playing chords was also required for this work. This is the only sonata in the set to include the violin as a soloist. Sonata III, comprising four contrasting movements, opens with an Adagio followed by a three-voiced fugal Allegro. The third movement is a Siciliano to be played in a broad style (Largo), while the conclusion is an extended dance-like movement.
