For any ensemble of roughly equal numbers of each sex
All players should sit in a circle and look around the room.
Upon catching the eyes of any other player, take a deep breath and release it, playing a single note for the time it takes to release your breath.
If the person who catches your eye is female, the note you play should be a major third higher than the last note you played. If the person who catches your eye is male, it should be a perfect fifth higher.
Feel free to change octave whenever you please.
At the beginning of the piece, your hypothetical 'previous note' is a low C. If the rules dictate that your next note should be C, stop playing.When everyone has stopped playing, the piece ends.
