Today in the elementary school where I teach music one day a week:
Me: What's this?
Student: A half-note.
Me: Good. What's this?
Another student: A polka-dotted half note.
Me: Er, no. Just a dotted half note.
Of course, once she said it, it stuck in the kids' heads, and at least one other student called it that during class!
The same class featured a game of Is It A Composer or a Pasta? (From the brilliant mind of Ashi Day.) The only two they got wrong were Donizetti and farfalle.
