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

It’s all of the above but mostly your brain. There are very old and frail people and children who can learn the guitar so it’s not really a strength problem. It’s the hand-eye coordination that takes years to develop. Your brain literally creates more neural links in the areas that are being used and trained, which is why a task that seems almost impossible at first can become effortless overtime.
