Create two series of simple instructions written with a marker pen on sheets of paper and read instantly by the group. One could be of concrete instructions, like “looong tones”, “melodies”, “very individual dynamics”, etc. The other could be of a more suggesting kind, even also absurd or paradoxical, like “bubbling”, “like the sun”, “something you don’t like”, “boring”, etc. I recommend having the sheets ready in a numbered sequence in separate stacks, and to have one index sheet for the teacher showing all the instructions. Then you will be free to choose from section to section and to find the desired sheet quickly. I also recommend bringing a marker pen and some empty sheets — who knows whether you will be inspired to some new idea…
Instruct participants that at each section, they are shown (by finger signs) the number of people that are to play. Within 10 seconds, one should decide whether to participate this time or not — this should be possible with some care given to look and hear around. Sections last as long as the teacher thinks they should — and terminate when a sign is given, followed by a new hand-sign for the number of players and a new sheet.

The main place on our wiki for this type of activities is in the library under Event Lists Game Template, but the task of adjusting the number of players on the fly is unique.
