I don't know if this helps people to make a quick distinction, as it is certainly a simplification :-) Nevertheless, one could say:
- the choreography is the 'what' - the orchestration is the 'how' It is very important to not confuse the what from the how. I don't know what composition is, other than that two whats always make another what, and two hows may make another how if sensibly combined.
