To bring many players into one music — coordination that serves the whole without silencing any part.
Built on Greek ὀρχήστρα (orkhēstra, the space where the chorus danced), from ὀρχεῖσθαι (orkheisthai, to dance); to orchestrate is to give many parts one shared floor to move on.
The bringing of many separate acts into one coordinated whole, in a way that serves all of them without silencing any one.
