Mozart’s Musikalisches Würfelspiel: Difference between revisions

Mozart's [https://en.wikipedia.org/wiki/Musikalisches_W%C3%BCrfelspiel Musikalisches Würfelspiel] (score [https://imslp.org/wiki/Musikalisches_W%C3%BCrfelspiel,_K.516f_(Mozart,_Wolfgang_Amadeus) available on IMSLP]) is a system to create a waltz by choosing each measure from a list of possibilities, with 759,499,667,166,482 possible waltzes in total. This is an implementation of the Würfelspiel using a bit of Scheme code to select the measures at random, producing a different waltz at each compilation. The code is an instructive example of creating music functions and manipulating music in Scheme.
