Music Composition using Probabilistic Analysis

[pranavashok]

Hey!

I'm a computer science student (with almost zero knowledge about music) and I was working on music composition using computers for my project. It takes MIDI files as input, analyses it and creates a prediction suffix tree (maximum 3 notes in a node). Then it creates an automaton out of it where the transition probabilities are the probabilities of producing certain notes from any given state.

Here are two results it produced when I gave vathapi ganapathim as input:

Hopefully the result is in the hamsadhwani raaga itself.

Please do comment after listening and give your suggestions. I was also hoping if anyone had a collection of carnatic/hindustani MIDI files.

Thanks!

I would like to feed in a Bhairavi or a Kambhoji to your system and see the outputs. when gamaka comes in.

It would fail to capture the essense of gamakas, because in a midi file, gamakas are stored as simple notes with a pitch bend attribute. As of now, I haven't dealt with that. If you could provide a training sequence (MIDI file(s)) for Bhairavi or Kambhoji, I can post the result here.
