I'm fairly new to the electric guitar and currently learning about string muting (as in noise reduction) while soloing. The usual advice is to mute the lower strings with your right hand and the higher strings with your left index finger.
However, I saw a video of Petrucci where he talked about muting all strings with the right hand by forming a little notch where the pinky meets the palm. In there, one string can ring while the others are muted (by pinky and palm). I guess the idea is to always move this notch along while picking. I tried this today, and it seems like I can get this to work if I put enough effort into it.
Now before I do that, I wanted to ask if you guys think this is a feasible muting technique to get used to for a beginner. I'm not experiened enough to tell whether this technique is to be applied to normal melody playing or only for certain situations. I guess there's a reason why this isn't the gold standard of muting.
So I just wanted to get more professional judgement on this. Thank you!
