Understanding Orchestras

Section Imbalance

Orchestras often have a noticeable imbalance in the number of instruments across different sections. For example, the Berlin Philharmonic has 81 string instruments but only 19 woodwinds, 15 brass, and 5 percussionists. This imbalance is due to the volume each instrument produces; louder instruments require fewer players and are positioned at the back of the orchestra 1.

The loudest instruments are the ones that require the fewest people.

String instruments, especially violins, produce less sound and thus need more players and are placed closer to the conductor and audience 1.

   

Instrument Roles

Each instrument in an orchestra has a specific role and significance. The principal or first chair of each section leads and performs solos, with the principal first violinist, known as the concert master or concert mistress, ensuring everyone is in tune before a concert starts 1.

An orchestra is organized in a couple different ways. Each section will usually have a principal or first chair.

Orchestras may also bring in soloists for certain performances, often for ticket sales, although any rostered musician could perform solo parts if needed 1.
