The work consists of three movements:
Largo – Allegro
Andante
Allegretto
The sonata opens with an exceptionally slow introduction, in which emphasis is put on the equality of the two instruments, kept throughout the entire work. The second movement has a melodic feeling of adagio, which was the tempo written down by Mozart at first, but then crossed out and marked Andante. In the development section there are bold chromatic modulations. The final movement returns to the playful mood of the first, but even so happens to be a very sophisticated Rondo.
