Thanks for the thread JB! and thanks to shanty! I've been befuddled by the same question many times.
Is there something comparable for banjo? I "know" of ten or so tunings but since I love to use 'full' chords in the "brush" part of frailing I felt limited not knowing what made what chord.
I always felt that if I knew music theory I could figure it all out but MT just doesn't register in my brain.
good stuff guys!
