My teacher, back when I was having classes, told me I should use the fingers 1, 2 and 4 when fretting, when there’s a whole tone of distance between the frets, like on low E and A strings when you’re playing the major scale on 3 notes per string. When I started doing that I had hard time stretching fingers 1 and 2 apart, but it got easier, EXCEPT higher up the neck around the 12th fret, at lower strings despite having my thumb really low behind the neck.
Fret 5, big frets, easy to stretch
Fret 12, much smaller frets, but way harder to stretch?!
This makes doing legato and chords in these regions very difficult. It even hurts sometimes because of the amount of effort to keep my index still and not have it slowly slide up, closer to the others. Doing stretching exercises up there feels awkward, I don’t feel the good “burning” pain I usually get when doing stretches, so maybe it’s not even a stretching issue?
Should I just give up and use my ring finger instead? This is an easy solution but it still bothers me to have to give up like this, and I’d like to know first if this is normal and if there’s a better way to work on this.
Thanks!
