so, im working on george lynches solo from tooth and nail

heres a video:


and the very first part of the solo goes


on the high e

the hammer from 9 to 14 is a bit of a stretch and is played a bit like a trill. iv been working on this with a metronome for the last couple of days and all seems good except my fingers on my left hand (freting hand) always feel a bit stiff afterwards, making it a tad harder to go onto playing something else.

i cant loosen back up just by playing some scales for a bit, but i can go on like this. so, any tips?
