Johann Sebastian Bach Chorales Dataset

Source

This dataset contains 382 chorales by Johann Sebastian Bach (in the public domain), where each chorale is composed of 100 to 640 chords with a temporal resolution of 1/16th. Each chord is composed of 4 integers, each indicating the index of a note on a piano, except for the value 0 which means "no note played".

This dataset is based on czhuang's JSB-Chorales-dataset (Jsb16thSeparated.npz) which used the train, validation, test split from Boulanger-Lewandowski (2012).

Motivation: I thought it would be nice to have a version of this dataset in CSV format.
