What do you mean when you say "MozartBot reimagines Beethoven's Moonlight Sonata 1st Mvt"? That MozartBot somehow got to something that resembles Moonlight Sonata? Or that you somehow fed Moonlight Sonata into it and asked for a variation?

Ok, the answer is in there: you fed in the chord progression.

Actually these were the best results, not the original compositions, but even those are great for game soundtracks.

I'm impressed, very impressed.

RagtimeBot is probably the most consistent and produces the best results. Because its dataset is simpler?

Thank you sir. I agree that RagtimeBot is the best, and its dataset is indeed simpler in the sense that the rhythms and note structures are very similar among all data points. I.e. The left hand usually plays low bass note on beats 1 and 3, and higher chord on beats 2 and 4. The right hand is usually monophonic, with a syncopated rhythm.

The Beethoven dataset had the largest "note vocabulary" and thus had a harder time generating nice sounding music.

should add a dataset for the emotions
