Today I picked up Piano for the first time. I already play some violin, and I have practiced kendo a while ago, so these may become confounders. As I was learning fingering for the C scale and I managed to do the exercise slow and correctly after an hour, I tried rushing the tempo and did the exercise as fast as I could for as long as my arm went tired, without care that I went out of beat or made many mistakes. I noticed that when I played slow again, I got exponentially more better at the exercise. I tried to do the same with the other hand and the results were similar, I became proficient in very little time.

This made me think, perhaps motor skills are quicker to learn if you make a strong stimulus to myelinate the required nerves before developing fine control. I remembered that the bone does a similar thing when after a fracture, it develops a lot of callus and afterwards it gets remodelled and finely sculpted.

Have you had similar experiences learning motor skills or do you know existing learning techniques using this phenomenon? Could something similar work for other kinds of learning?
