Dragonfall, chapter 13

At first, they're just creepily silent; then they begin creepily humming in unison. I feel that sense of unease again, and it only becomes all the worse as their humming transitions into a surprisingly upbeat and jaunty tune. The foals bounce in place as they follow along with us. Worry transitions into sheer dread, and I finally let out a pained groan when the air suddenly fills with the sound of musical instruments from an unknown source, matching their tune. It's exactly as I feared. They're starting a heartsong.

I'm terrible at heartsongs.
