String section
The string section is the largest body of the standard Classical orchestra. It normally consists of the first violins, the second violins, the violas, the cellos, and the double basses (or basses). In discussions of the instrumentation of a musical work, the phrase "the strings" or "and strings" is used to indicate a string section as just defined. An orchestra consisting solely of a string section is called a string orchestra. Smaller string sections are used in jazz, pop and rock music arrangements.
Seating arrangement and roles
The most common seating arrangement is with first violins, second violins, violas and cello sections arrayed clockwise around the conductor, with basses behind the cellos on the right. The first violins are led by the concertmaster; each of the other string sections also has a principal player (principal second violin, principal viola, principal cello and principal bass) who play the orchestral solos for the section, lead entrances and, in some cases, determine the bowings for the section (the concertmaster may set the bowings for all strings, or just for the upper strings). The principal string players sit at the front of their section, closest to the conductor and on the row of performers which is closest to the audience.
