What’s a Metronome?

I love a metronome!

It acts like a little drum when we’re making music and it helps us keep time.

But, what is it and how does it work?

I don’t know why this person has put wings on a metronome, but it’s pretty and we get to see how the mechanics work.

Although, you won’t find any wings on my metronome, you will understand a bit more about what’s going on inside.
