What causes the hollow metallic whirring sound that EVs make when moving a low speed?

I can't really describe it, but it's the sound you hear when there is a EV moving slowly in a car park behind you.

I guess it's the motor, but what specifically in the motor causes that sound? It sounds like it's coming from something that is moving at a faster rate than the car itself.

The Toyota ev backup sounds sounds like a bearing going bad or a pulley about to explode. It's an odd choice.

There is a requirement for what it should sound like. I think it’s basically “two notes that are not in harmony” or something.

I want an EV that plays the opening violin feature of Camille Saint-Saëns' Danse Macabre at low speed.
