The group exercises, in their first draft will involve just 3 people.
I have produced 3 different keys : one for solo movements, one for movements in pairs, one for movements in the full trio. All three keys being available ensures that each participant can be moving at all points. These keys provide the 2D sign alongside their full, in motion, description.
I have also written the notation for 5 individual routines which are based completely on the keys. This notation depends on these keys for their understanding, but information can still be inferred from these diagrams alone.
