Chords — Upright Bass
Pick a root. Every quality, drawn for this chair and read against the keys a circle calls.
The chord reference for this chair. Pick a root, then any of 54 qualities, and get the shapes plus the thing a chord chart never tells you: which of the keys a caller actually calls contain it, and as what number.
The bass chair owns the root and fifth on the downbeats. Almost none of a chord is playable down here and almost none of it is wanted: the room hears whichever note you put at the bottom as the chord, so the choice is which one, and when.
The diagrams below mark stopping points on the EADG fingerboard, not frets — there are none. Treat each dot as a place your finger has to find by ear, and use the playback to check that it did.
