I’ve been trying to play some more teaching games with Anya. Today’s activity was building our own guitar-like instrument. A small box with a hole cut in it would work well, but we used a couple of her board books. Stretch a few rubber bands around the book (I’m a little uptight, so I put them in a specific tonal order … hers are a haphazard arrangement), then insert something under the bands along the book to raise the bands up a little bit from the book. A wooden block, a marker, and a glowstick all worked well. If you put the object toward the center of the rubber bands, then you get two different notes per band.
