Время создания: 1800-17 (?)
Only the first movement and the first 43 measures of the second movement are extant. It is unclear whether any more than this much was ever written out by Beethoven. The addition of piano gives the trio a depth that is lacking in the string version--in particular the long crescendos on pounding eighth notes have a much greater effect here than in the original. However, the piano part is rather simplistic and little is added to make it more interesting. As in the original, Beethoven humorously injects several false conclusions to unsettle the listeners.
