this is a guitar file you can use to train for alternate picking and to prepare your self to play technical difficulties
this is for more than a beginner , but if you are willing to try - go for it. I will say this , each measure should start with a down stroke and after that be carefull that every pick is perfect alternate( meaning up-dow-up-down)
the reason I believe this will help is that not only are you playing with a metronome( don't forget to turn the metronome on) but you are following note for note
Slow the tempo down so you can play it perfectly and no I can not play it as fast as paul gilbert , but this has really been helping my practice
