Model jazz trained on jazz standard midi data.
Training data
All the training data comes from my corpus of jazz midi files that I've collected from the web. I picked some from the start of the alphabet, taking a few midis for each song.
The model's trained on 12 midi files, each truncated to 50 half-bars.
