Real Alarm Clock
F4 on the minor comb. Its drum rings at 349.3 Hz.
An old wind-up alarm clock runs on a spring: winding the key tightens the spring, and as it slowly unwinds it turns the gears and the hands.

Its note
Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 349.3 Hz, right on F4. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

About it
An old wind-up alarm clock runs on a spring: winding the key tightens the spring, and as it slowly unwinds it turns the gears and the hands. Two metal bells sit on top, and when the alarm goes off a little hammer rattles back and forth between them.
Its hands show the real time on this device, in its local time zone, and the red second hand ticks once a second. Tap it and the twin bells ring while the clock rattles across the table. Before alarm clocks were common, some people paid a "knocker-up" to tap on windows with a long pole and wake people for work.
