These quartets represent a considerable advance on the Milanese Quartets from less than a year before. Each contains four movements, including minuets and trios. Mozart had been exposed to recently published quartets by Joseph Haydn (Opp. 9, 17 and 20) and was incorporating many of their elements.
The slow movement in F minor is a triple-meter canon on the familiar theme also used in the finale of Haydn's Op. 20 quartet in the same key. The finale is a fugue which is also similar to one of the finales of Op. 20, this time the A major quartet.
The opening movement is a theme and variations with a theme that resembles the variation theme used in Haydn's Quartet Op. 9, No. 5 in B flat. The second phrase of the slow movement contains the opening theme of Haydn's Op. 9 No. 4 in D minor.
