Beethoven’s String Trios are masterly in form and content and, with Mozart’s only string trio, the Divertimento K. 563, are among the most significant works in the entire genre. Beethoven’s first, Op. 3, is an ambitious six-movement work probably modelled on Mozart’s work and ending, as does Mozart’s, with a brilliant Rondo in opera buffa style. His second, the Serenade in D major, Op. 8, shows Beethoven experimenting with form, and employing greater contrasts of colour and texture.
