Setup

Collectively, choose one of the pieces [A-K, see above].

You may practise contents first if you need to.

Gameplay instructions

One player indicates by hand-sign a number between 1 and 5. Everybody then plays according to the instructions belonging to that number, until someone else indicates a new number. Sections with a new indication can may follow each other fast or slow as you like.

No pre-arranged sequences neither of elements nor of musicians indicating numbers.

Game end

The piece ends when there is no playing and no one takes a new initiative.
