The Fatal Fall of the Metronome

Tick tock, tick tock, tick tock, tick tock.
My poor old 'nome, my spouse does knock.

Over it falls, loud crash I hear.
Say I, it survives, I do not fear.

For twenty years of falls, it misses not a beat.
What's one more fall of just a few feet?

But now it quietly goes tick tick.
Fainter, fainter, it goes click click.

Alas, I cannot hear my metronome.
It must go to its final resting home.
