I always used to practise a lot more sitting down than standing up and I'm trying to shift that now towards playing more standing up, but I have some issues with my fretting hand when I play standing up. I find it very hard to stretch across more than two frets using my index finger and pinky. My pinky wants to curve inward towards my index finger and it's very hard to move it in the other direction. If I force it out it ends up flattening out and putting my wrist in a very unnatural angle that doesn't feel good at all. Say that I'm playing a riff that goes something like this: -----5-----5----- 2-2---2-2---2-2- If I'm playing that I will kind of move the whole position of my my hand very quickly between the notes kind of like I was playing this (I play power chords with index and pinky): 4-4-5-4-4-5-4-4- 2-2-3-2-2-3-2-2- I guess I have pretty small hands but, is this like, normal? It seems to me like 3 frets shouldn't be that hard to stretch, and I can do it okay sitting down. So I wonder what everyone elses experience is with this kind of thing and if anyone got tips for me?
