All good-sounding, choral 13th chords

Here is a PDF of all good-sounding choral 13th chords (excluding transpositions) along with a MIDI. It contains 203 chords in an extreme choral range: F2 to A5, sorted in an order useful for music composition purposes.

This list also contains about fifteen chords which don't sound as good. However, I didn't detect a pattern I could use, in order to remove them automatically.

I removed all chords containing:

• Minor seconds;
• Minor ninths;
• Tritones;
• Two consecutive major seconds;
• More than two major seconds;
• Major seconds starting lower than F3 or higher than F4;
• Gaps greater than an octave which resume higher than F4.
