In the dromoi
None of the dromoi on this site lists Gdim7 among its chords, so it is shown here as a shape reference.
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, 5-4-2 on trichordo, becomes C 7, A 4, D 2 on tetrachordo, with the F course left out.
