Re: What to do with a rogue left hand?
Wow, my teacher was right when he said this forum has lots of participation. Should have mentioned I'm using matched grip. I'm going to copy all your suggestions into a crib sheet and set it next to my practice spot. Also, I'm going to pick some songs I like that have good left hand work, and try the old play-along method. If I mix that with ordinary exercises, it could help reduce the punishment aspect. The music I'm pursuing is alt-rock, generally mid tempo with a bit of creativity in the percussion to support the song structure. (The only thing unusual I want to learn is African polyrhythms; I'll deal with that in other posts.)
I believe my digital camera can make short videos, so I may be able to offer those next time around! Thanks all.
A good groove shows accuracy and emotion.
