Various warm-up games where players stand in a circle and pass a signal — usually a clap — according to a fixed pattern or randomly.
Basic version: Pass a clap to your neighbor as quickly as possible around the circle. Try to make the clap travel seamlessly, as if it were one continuous sound.
Variant: A clap to the right passes clockwise. A double-clap reverses direction. A clap with eye contact across the circle sends it to that person.
