If you like procedurally based music - you should definitely check out CPU Bach, a program written by Sid Meier (the Civ series designer) for the 3DO console back in the 90s. It doesn't use markov chains (to my knowledge) but can generate some pretty impressive sounding Bach-like preludes / fugues using a weighted rule based approach across notes and melodic phrases. https://www.youtube.com/watch?v=IbGO0a5P0M8 https://www.youtube.com/watch?v=IbGO0a5P0M8
