Ok, I usually not into playing this type of stuff, but I need your advice. While learning "ode to joy" I`ve decided to open a random song in guitar pro, and ended with metallica`s master of puppets. The thing is, I can`t play it. It`s too fast for me to play it clearly. My question is - will playing it 200 times at 50% or 75% (I can play it at that speed now) help me evolve necessay precision? Or should I leave it and come back next year? I know that learning slow is usefull when song is difficult due to hand coordination, etc. - I do that all the time - but when it comes to plucking speed, speed and speed alone?
