by misfretting a 220202 Bm7/F# and moving it up the fretboard:
Bm9/F# = 22022x C9/G = 33033x Am+11 = 55055x Bm+11 = 77077x
I'm picturing some melody like | c#3 B/2 c#/3 | d3 f# | over a nice, slow two-bar | Bm9/F# | C9/G | pattern. Mmmm.
I swear, this instrument is, like, optimized for happy harmonic accidents.
