"In 1787, Mozart wrote the measures and instructions for a musical composition dice game. The idea is to cut and paste pre-written measures of music together to create a Minuet.

This site is an implementation of such a game. The music and table of rules for this game appear to have been published anonymously in 1787, and interestingly, the table of rules for this Minuet is identical to Mozart's. However, it is not clear who the composer of these measures is."
