Ask HN: How to keep my daughter busy while tickling her curiosity
There has never been a better time to be a self-guided music learner. When I was 11 I would have flipped right out over the possibilities available in tools like Max, an interactive visual programming environment for making audio, visual, and music programs and installations. And combining it with Arduinos is also amazing for kids (ok, for anyone!). You can try max out for a very low monthly subscription now ($10 or something similar) and there are tons and tons of wonderful online resources for learning it.
