Alternate Picking FAQ
Question: "When you alternate picking the string, do you rest the side of your palm on the bridge, or do you just pick the notes freely, without the right hand touching anything?"
Answers:
"When I play the lower strings my hand is over the body or just in the "air" (actually the forearm is over the body resting). And when I play the higher strings the hand could be over the lower strings muting them."
"For low strings I rest my right hand on the birdge, and avoid letting it touch the strings. For high strings I just palm mute every string below."
"Quite simply I roll my palm over the strings I'm not playing."
It is a matter of personal preference, try both ways, and see what is right for you."
