A Humdrum Edition of the Bach Chorales is available at http://kern.ccarh.org/browse?l=371chorales

The data files can be downloaded using the humcat and humsplit commands:

    mkdir chorales
    cd chorales
    humcat -s h://370chorales | humsplit

This should create 370 files in the format chor001.krn, chor002.krn, chor003.krn, etc.

Convert a particular chorale into a MIDI file with this command:

    hum2mid chor001.krn -o chor001.mid

Each chorale is hand-labeled with a musical key. To generate a histogram of key designations in the chorales:

  extract -f 1 *.krn | grep '\*.*:' | sort | uniq -c | sort
