Very simple song reharmonization
Hallo folks, I have a question considering one weird song "my" three singer ladies would sing and that is nothing but a to an fro between the chords: f# and g.....
Since that is quite reduced, the only thing I could imagine is, that f# would either be a tritone substitution of the dominant C, and G just the tonic, or the other way round that G would be some substitution, like TT sub for subdominant or something. But when I try to play neither of them would jive.
Any suggestions to get out of the simple f#-g corset?
Thanks for sir patience
