Next week, I'll bring my harmonicas and show them to the older ones. It's important to me that they see and hear as many instruments as possible. I'm also working on a set of music theory flashcards for them, but this is turning out to be more work than I thought it would be (it is ever thus). I'm doing them in colorful inks, which I hope will make the rote learning a bit more fun. I've been doing some music theory with the big one and she soaks everything up like a sponge. I want her to be able to play from chord symbols and would quite like to get her started on the guitar (guitar is my main instrument).
