Chords — Mandolin
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 mandolin chair owns the chop on the backbeat, and a chop is a chord with the ring taken out of it — closed shapes only, four courses damped the instant they sound, landing where a snare drum would.
Every shape below is drawn for GDAE, 4 courses, 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.
