Press start.
This is supposed to be using a first order Markov Chain, however I think that the chain data I am using is not accurate, rather just the results of this experiment by Prathusha Boppana and Jie Zhang: Using Markov Chain to Compose Music Pieces, https://www.math.utah.edu/~gustafso/s2018/2270/projects-2016/zhang-bopanna/zhangJie-bopannaPrathusha-MarkovChainMusicComposition.pdf They said they used data from Bach and other composers, so it might sound classical, that's up to you to judge! I might come back to this and use better data. Perhaps I can get my own data from specific songs. Yeah it kinda sucks, but it only took me 3 hours or so, so with the right probability matrix it might sound better.
