Chords — Guitar
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 62 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 guitar chair owns the boom-chuck floor: the bass note on 1 and 3, the strum on 2 and 4, and the chord shape is what decides which bass notes are even available to walk between.
Every shape below is drawn for EADGBE, 6 strings, with the open shapes first and the movable ones up the neck after them, and each one plays back so you can hear it before the circle does.
