Some might see my disabled music students as full of unpredictable challenges. I prefer to think of them as quirky.
My students are definitely quirky:
One of my students who has autism pretty much speaks only as Dora the Explorer.
Another autistic student uses swear words to get my attention. (I bite my lip to keep from laughing when they do that. Ignoring it is the best tactic I've found.)
I have a few students with ADHD who keep me on my toes. Sometimes jumping jacks are the only way to get some of their ya-yas out.
The other day I was teaching a young student my little trick to memorize the B and D around Middle C. I credit my mother for teaching me this trick long ago: If the staves are fences, the B (Bird) is at the top of the fence and the D (Dog) is at the bottom of the fence.
I drew bass B and treble D whole notes, and then I asked him to turn the B into a bird. So he put on a smiley face and added curvy lines for wings. He drew a speech balloon and asked me to write "chirp" in it.
