Trichordo (D-A-D) and tetrachordo (C-F-A-D)
These shapes are for the three-course trichordo. A tetrachordo’s A and D courses are tuned the same, so the top two notes stay put and the low-D bass note moves two frets up the C course. The first shape, 9-9-7 on trichordo, becomes C 11, A 9, D 7 on tetrachordo, with the F course left out.
