Just curious if this is one of the things that develops over time without any intentional effort (does this ability sneak in through the back door while you are learning other things) or if fretboard awareness is something people work on. If I'm not moving my hands, I don't have a problem playing open chords and mostly fingering them accurately, but I'm a bit amazed when I see experienced players playing involved solo's, or even just bar chords where they're on the 3rd fret, for instance, and then jump up to the 10th fret and keep playing accurately. I'm also just curious what the cues, if any, are. Is it an unconscious perception of neck diameter, or just motor memory as to how far up and down you need to move your hand to get to the right spot? Are players uncounsciously counting frets as they slide their hand up the fretboard? Should I do any exercises to become more proficient at this? Thanks.
