I'm working on "Orange Blossom Special" on my fiddle and to do the beginning...(train sound, horn etc.) I have to go really fast with the bow....and one of the "tricks" is to flex the wrist back and forth....Well....when I then pick up the mandolin, it seems that I'm doing the same thing....which according to FM is a "NO NO"...AGHHHHHHHH!!!!! Drives me crazy....(not FM, but the not being able to keep the "tricks" with the right instrument.)
Guess with practice and experience everything will fall in place (I hope ) but right now it's driving me nuts!!!!
