Sketches of the first version of the slow movement of Beethoven's String Quartet in G, Opus 18 Number 2, have been reconstructed by the Manchester music professor Barry Cooper.

The original sketches were thought lost, but rediscovered in 1977.

According to Professor Cooper: "This movement is of particular importance as it stands out as the last substantial work that Beethoven composed in full and apparently had performed in 1799 before it was discarded and lost."
