Reminds me of a piece I heard on Radio 3 before my ears gave out. Can't remember the title as it was Japanese, nor the composer, Japanese again, but it was about learning to play the recorder.
It starts off with seemingly aimless toots, as a kid might make, but all in the score. It then progresses to a basic tune that the player appears to struggle with - and when they finally get it right, you feel a sense of relief. Then from the basic tune, you get more embellishments until frankly, you hear something that is very hard to play and a work of virtuosity. It's an astonishing work, but not something that most listeners would appreciate.
The recorder is something that most folk have heard played by a schoolchild, but few have heard played really well.
