Bessie is a practice tool for chromatic movement built around the concept of the tesseract. Play any chord of a relevant quality (diminished, 7, M7, M6, m6, M7#5, 7b5, or minMaj7), in any inversion, and bessie will tell you what chord you played + suggest another chord a mere half-step away.
If you play a chord and it doesn’t seem like bessie got it right, press K2 to clear the cache.
Bessie ignores repeated notes, so you can duplicate notes in your voicings and bessie’ll still work pretty good.

I know that it would be very easy to build an expanded version that includes a wider variety of movement or chord types, but it’s really important for me right now to sit with this particular harmonic concept and let its many sounds sink in. This is a spike for a larger project, tentatively titled 6DIM, which will offer many axes of sequencing manipulation (like colorwheel’s dissonant brother). Bessie outlines one such axis.
