It's rotational, in no order A/C clutch, pulley/tensioner, Water pump or alternator

 

try turning on the AC and see if it quietens down

Thx. Can it be timing chain?

Model (petrol, diesel, hybrid), mileage, service history and how long have you owned it?

try putting a screwdriver on alternator bearing housing and your ear to screwdriver handle.

It may help you to eliminate the altinator.

Make sure you dont slip off and anto the belt!.

2017 Toyota Yaris 1.5l 4dr hatchback 72k miles. about 3 years. Did only oil changes 0w20 Mobil and pads and rotors nothing else. Runs like new. Just that noise

Water pump very likely or as been mentioned alternator bearings, or AC compressor.. These are first checks and use the same method with screw driver to check them. Be careful though. Can watch some YouTube video how to test water pump before you start checking.

To me it sounds a bit like a separated crank pulley. These are often 'harmonically dampened' and consists of an inner hub and an outer ring connected by rubber. The rubber can sometimes let go and the out ring loosen from the hub. It will still work but you get a clinking sound similar to what you have. 

That said, the speed sounds higher than the crank. So it would be likely something driven by the engine.

In any case, loosen the tension on the belt(s) and feel all pulleys for play or lateral movement.

I think it is water pump. I took belt and water pump makes sound also has some movement.
