Being an Architect is like being a conductor1 in an orchestra. You’re not playing all the instruments, but your job is to make sure everyone is in concert [pun intended] and that the result is harmonious.
I once saw Simon Rattle conducting 6 Berlin school orchestras playing Edvard Grieg’s Peer Gynt Suite. As a matter of fact, they never worked nor rehearsed together before. Their first play was awful and cacophonic, but after multiple corrections and rehearsals, Rattle transformed the final performance into a beautiful and majestical piece.
