Low E string on the left, high e on the right. Each column climbs the neck, position by position; the open-position voicing is fixed to this key. Some voicings are extremely difficult or impossible — attempt at your own risk.

Tensions Over Every Bass Note

What each note in C-Db-Gb-Bb becomes when you slide the bass underneath it, chromatically through all twelve — plus the normal chord symbol, wherever the resulting stack has one. Click any chord symbol to hear it played over that bass note, or click a bass note itself to drone it while you try voicings above.
