what happens when my hand can suddenly execute with ease a finger movement and stretching sequence on the guitar which I found physically impossible a few days back?

Question

Does my brain adjust? Do my fingers stretch more? Do my hand muscles build up?

Answer 1

Brain adjustment. If you’re carefully concentrating on something and practicing it, your brain doesn’t stop when you put the guitar down. It keeps thinking about those moves, and it can create new neural connections to help execute it next time.

Often that’s good, and the task suddenly goes better the next time you attempt it. It is possible for your brain to form bad connections, and you pick up a screwy new habit that you have to un-learn, but in general you get ‘bonus learning’. This happens more if your practice sessions aren’t too long, and if you stop before you feel burnt out.
