The first chair of a section sits at the front of the section, but not necessarily in the front row of the orchestra. The seating arrangement of an orchestra is typically determined by the conductor and can vary depending on the piece being performed and the size of the orchestra. In general, the first chair of each section sits at the front of their respective section, followed by the second chair, and so on. The front row of the orchestra is usually reserved for the concertmaster (who is the first chair of the violin section) and the principal players of other sections, such as the principal oboe, clarinet, bassoon, and trumpet.
