This is not strictly about “Playing Technique” so apologies if this topic is in the wrong category, but it is related to how I play. Recently I’ve been practicing a lot, could be 1 to 2 hours a day broken into many small chunks of 15-20 minutes. I play sitting down and standing up, and when I sit down I consciously try to sit up straight. Recently I’ve been having a lot of muscle tightness on my right shoulder and around the base of my neck and very upper back. I wonder if this is because I spend a lot of time looking down and to the left towards the fretboard? Does anyone have any advise on this?
Thank you very much
