I’ve been playing guitar for a couple years. Just recently got into metal core. Been playing in drop C. When i play that type of music my arm gives out kinda. Like doing really fast palm muting and alternate guitar picking. Am i doing it wrong? Because the muscles in my arm start to hurt after a couple of minutes of playing a song. Just recently had this problem. Is there a way i can play fast without straining my muscles? I never have pain in my wrists hand or forearm. Just upper arm.
youre tensing the muscles in your arm too much, sit down, and wear the strap for complete support, and try and loosen it, it will involve changing the way you play slightly: or just get the muscles in your arm more built up: thats what i did
I tune my guitar B-F#-B-E-F#-B, so my strings are even looser. it does make things slightly harder
