Black Hole
D5 on the major comb. Its drum rings at 558.1 Hz.
A black hole is a place where gravity is so strong that nothing that crosses its edge, the event horizon, can get out again, not even light.

Its note
Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 558.1 Hz, 88 cents flat of D5, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

About it
A black hole is a place where gravity is so strong that nothing that crosses its edge, the event horizon, can get out again, not even light. Gas that falls toward it swirls into a flat disk and gets hot enough to glow.
Tap it to feed it a star: the star spirals in faster and faster, is stretched into a streak and plunges in, and the disk flares. In 2019 astronomers showed the first picture of a black hole's shadow, at the heart of the galaxy M87, made with radio telescopes spread across the Earth.
