The Science of an Orchestra

YOU DID NOT HEAR MUSIC. YOU WITNESSED COORDINATION.
An orchestra is not a group of people playing music together.
That description is comforting and wrong.
An orchestra is a temporary agreement between dozens-sometimes hundreds-of highly trained individuals to surrender personal agency in exchange for coherence. It is a real-time systems experiment involving physics, biology, psychology, authority, memory, air pressure, wood that is slowly failing, metal that is always lying, and a shared commitment to not proving who is smartest in the room.
When it works, we call it beautiful.
When it fails, we call it rehearsal.
