> Choreography brings the idea of dancers in sync without the need of a central conductor.
Try that and let me know how it works.
In reality, the dancers are of course synced by the music, dependent on the same conductor as the orchestra.
And on top of that, orchestration isn't the conductor's job. It's the composer's (or arranger's) job, putting it exactly parallel to choreography. The orchestrator, like the choreographer, determines who does what and when they do it, and he does it in advance. Most typically, years or centuries in advance. The conductor determines how fast the clock runs.
