Hello everyone,
i tried to learn eguitar years ago, but to be honest there was not much time i invested in it and dropped it. Also when i think back i lost a lot of motivation because i learned songs that dont really interested me. So years later now i want to give it a try once more because i have songs in my head that i really would love to play along. So basically i would consider myself a beginner with a bit of knowledge but yea i would say my hand and finger coordination is quite slow and not there for the song i would love to play. The song i want to learn is The Hell Song from Sum 41. I love the riff so much but man im not even close to hit it. So i wonder if its really dumb just to try it everyday and let time take over, or are there maybe excersizes to help me to get there. Right now my left hand has a bit of a struggle to stretch from fret 2 to 4 with my middle finger and pinky finger. Also right hand is not so confident to hit the single strings i want. So yea basically quite beginner lvl i would say. I know it will take time so im not delusional to hit this song in a few days or so on. But what would you guys recommend if you start new?
Thanks a lot :)
