This is astounding video reminds us of the capacity for children to learn music. I am guessing, with great confidence, that those children did not learn how to do that without an incredibly dedicated parent at their side and hours upon hours of daily practice.
Those of us who don’t have or don’t want to spend hours every day practicing with a child can still be encouraged that our smaller but persistent efforts will also pay off, because it’s simply a proven principle: “That which we persist in doing becomes easier for us to do, not that the nature of the thing itself is changed, but that our power to do is increased.” (Ralph Waldo Emerson)
