My left hand fingers are not straight on the fretboard, indeed the calluses on the index and on the pinky are not in the centre of the fingertips, but I have them on the side of the fingertip, next to the nail. I tried to put my fingers perfectly straight on the fretboard but its a lot of efford. Is it so wrong if I cant press the frets with the very point of my fingers, and shall I correct this? Or it is irrelevant?
It's not irrelevant if playing super fast and clean is in your future, but if you're doing everything you want to be able to do and you're not in any pain, it's cool.
