There is usually some confusion concerning the correct key for group performance when there is a mandolin player in the specific group. Fretmentor sometimes has written the music (breaks) for specific instruments in different keys. That's not abnormal and should be considered a music sanity check. My general advice to the guitar and banjo players is --- when in doubt -- ask the mandolin player. Guitar and banjo players can easily capo to the correct key, but with the mandolin (there are mandolin capos!)if you have to capo up the fingering gets difficult since the fret distance starts getting microscopic.
Based on Fretmentor mando breaks, I put together and handed out a "cheat sheet" of keys for the Bluegrass class songs for mando players. That way, mando players can confirm the key for a performance group Unfortunately, I can't seem to find my copy, but one song indicates the incorrect key. My challenge to mando players is -- which song is it?
and I believe you gave me your copy!
