The notes for this were transcribed by a neural net in the Python library, piano_transcription_inference.
Let me know if you want other piano pieces to be transcribed.
It's a bit fiddly to setup, and only works well for pure piano audio -- otherwise it throws in lots of junk. Also, if a sustain pedal is held over many notes (like this piece!), the result will need manual editing.
But I can explain if you are interested.
