In an orchestra, the "first chair" is the best player in their instrument section. The first chair violinist is known as the concert master/mistress.

"The concertmaster (from the German Konzertmeister), first chair (U.S.) or leader (U.K.) is the principal first violin player in an orchestra (or clarinet in a concert band). After the conductor, the concertmaster is the second-most significant leader in an orchestra, symphonic band or other musical ensemble."
