Some people use the terms Choreography and Orchestration as synonyms, some claim they describe different concepts. A few days ago, I heard a very convincing reasoning. I’m not sure where it comes from:
In orchestration, there’s someone — the conductor — who tells everybody in the orchestra what to do and makes sure they all play in sync.
In choreography, every dancer follows a pre-defined plan — everyone independently of the others.
You may question the result. But the explanation is great :-)
