There is a widespread belief that this movement is an affectionate parody of the metronome, which had only recently been invented (or more accurately, merely improved) by Beethoven's friend, Johann Maelzel. Specifically the belief was that the movement was based on a canon called "Ta ta ta... Lieber Maelzel," WoO 162, said to have been improvised at a dinner party in Maelzel's honor in 1812. However, there is no evidence corroborating this story and it is likely that WoO 162 was not written by Beethoven but was constructed after-the-fact by Anton Schindler. A more likely inspiration was the similar rhythmic parody of Joseph Haydn's "Clock" Symphony.
