@ggreene66 , I’ve found that difficulty creating a certain reach can be caused by a variety of factors. Off the top of my head:
- position of the guitar relative to the player’s body/the player’s body relative to the guitar; there isn’t one perfect position but depending on the player, the guitar, and the particular challenge, there can often be tweaks to make reaches easier.
- position of the left hand thumb on the back of the neck - again no perfect ‘position’, it’s all relative to the big picture
- fingertip placement - ‘sides’ vs tips , or degree of slant towards/away from nut
- amount of ‘curl’ in finger joints
probably lots of other things too, obviously the first bullet point there would have a dozen little subcategories
I think that posting a vid of you trying to do the thing that is tripping you up could be helpful. With fretting hand stuff for rock, if you post on forums you might see some people saying “angle the guitar neck up, keep your thumb low on the back of the neck, use a footstool and/or put the guitar on your left leg” or see people argue against that and say you’ll get back problems and be sticking your wrist out, but I’ve found it’s often problematic/counterproductive to isolate little “parts” of fretting hand technique without checking out what’s happening in the big picture. Similarly, can be tricky to discuss things in a theoretical framework without seeing the’reality’ of the player’s current orientation
As a small example of that, I teach guitar classes and often am on students’ cases about what they’re doing with their legs and even feet…
