In the dromoi
On D, the trichordo’s home note, Bdim belongs to these dromoi:
- Souzinak: core chord (Bdim)
The same roles on other roots:
- Hitzaz on C: passing chord (C♯dim → Bdim)
- Niavent (Nihavent) on C: passing chord (C♯dim → Bdim)
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, 9-8-12 on trichordo, becomes C 11, A 8, D 12 on tetrachordo, with the F course left out.
