Hot potato for music. You don't have to play much at once, but you can make something collectively.
Preparation
Depending on a chosen form, you might need instruments that are able to produce very short sounds.
Setup
For this game it's best to stay in the circle.
Gameplay instructions
Basic version of this game lets each player make just one sound per turn in even rhythm. The tempo should slowly speed up so that mistakes are after some time inevitable. Falling off the beat, results in removed from the game until the end (drop-out).
As it's a free-form, you can go with it in many ways, let everyone play the same sound or stay on the scale. Mix things up with changing direction or playing not one by one but every two or every three people in the circle. More examples will be added here, but it's always a good idea to come up with some variants of your own!
Game End
It ends when everything falls apart. Sooner or later it does.

This is an example of a rich family of (often untied) "passing games" placed in a natural spot between many children circle games and musical arrangements like trading, chaining, drum circles and circlesongs. The family is in need of an article, but examples include "Drum Talk", "Orbit" and Melody-go-round.
Video inspiration
This game may sound busy, rushed and sharp in a basic form, but the same premise when dropping the speeding-up mechanic can have nice and sweet results. Here is a piece by The Orchestra of Crafty Guitarists:
