Apparently birds in flight perform odd rolls & turns, even to the extent of flying upside down, in order to shake the air/wind off their wings before coming in to land.
I wonder if guitarists do the same sort of thing? I find myself flicking my left hand down quickly in between certain phrases, probably as a reflex action to release the muscles (?) & in most videos on the net, one can see professional guitarists doing the same sort of thing, I think.
Is there an actual technique involved, or it is just a reflex action? Silly question, but it bugs me!
