This video from the 2004 TED Conference is extraordinary for a few reasons. First, the prepared performances by then-14-year-old composer and pianist Jennifer Lin are lovely and technically very accomplished. And — wow — the improvisation she creates on the spot (16:45) is really something.
But, I also wanted to draw your attention to her thoughts on creativity and flow — discussing how she tries to beat distraction and gain focus in both drawing and composition. Her discussion starts around 13:31, but do stick around after for her improv based upon randomly chosen notes.
