Sonic Pi and Mozart’s Dice Game to produce a Waltz

I have just completed a program on Sonic Pi which plays the waltzes produced by Mozart’s dice throwing game, which chooses the bars in the waltz from the scores of a pair of dice. I first visited this in August 2013, when I worked with python and the music engraving program lilypond to produce midi-files of the waltzes, and the associated contredanses.
In this new article, the sounds are produce by Sonic Pi, but you can also copy and paste the dice scores into a text file, from which lilypond will produce a manuscript of the music.

Full details, including downloads of all the programs required, and a video of the system in operation are contained in the new article which is here

  1. Robin, for the last couple of weeks (this year?) I’ve been receiving each eantry in your blog twice on my RSS feed. Have you any idea why this should be? It’s only yours that is so generous – other wordpress blogs are fine.
