Hi!, just one day before having a NGD, i got extremly lucky and broke my left thumb , the guitar can wait but I don't want to get too rusty in the month the doctor told me to wait, I will be practicing string skipping and downpicking, but it would be cool if you know some riffs that could be played with the right hand.
The only ones I'm aware of are a portion of battery and intro of nothing else matters
I don't care about genre btw
Stuff some tissue under your strings to mute them and then practice all you need. I did that to practice my tremolo picking on the classical guitar.
You could always tune the strings to suit a riff? Or tune it to an open chord tuning, and play slide guitar.
