I've always had trouble with my right hand...
Somewhere I got into the tendency of, say when I'm playing an arpeggio, alternate picking as I move up and down the strings, rather than... sweeping the pick down for lack of a better term. It seemed less lazy to do it that way at the time, so that's how I decided to do it.
I still trip up more than I'd like to. What's the "correct" thing to do? sweep, or alternate? Am I making this way harder than it needs to be, or is this just something I need practice with?
It's too ingrained in me to do anything but alternate now, so it would take serious practice for me to find out if sweeping was indeed easier, and if I found out it wasn't I would just have messed up my perfectly good (developing) technique
