Practice is great! But practice alone won’t make you Yo Yo Ma.
I agree with this article but the reason I agree differs from the researcher’s findings. As a music student, I was addicted to practicing. I could practice better than anyone else. The problem was that there is a difference between practicing and doing. If you’re just practicing, you will only become so good. As a music student and as a music teacher, I heard students say “but I did it perfectly in the practice room!” In my experience, it comes down to how you spend your 10,000 hours. It needs to be a balance between the practice room and the stage. You need to stay focused but distracted.
