String quintet String quintet A string quintet is a musical composition for five string players. As an extension to the string quartet (two violins, a viola, and a cello), a string quintet includes a fifth string instrument, usually a second viola (a so-called "viola quintet") or a second cello (a "cello quintet"), or occasionally a double bass. Notable examples of classic "viola quintets", in four movement form include those of Wolfgang Amadeus Mozart. Other examples were written by composers including Johannes Brahms and Felix Mendelssohn. A famous "cello quintet" is Franz Schubert's Quintet in C major. Antonín Dvořák's Quintet Op. 77 uses
String section String section The string section is composed of bowed instruments belonging to the violin family. It normally consists of first and second violins, violas, cellos, and double basses (or basses). It is the most numerous group in the typical Classical orchestra. 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 sometimes used in jazz, pop and rock music and in the pit orchestras of musical theatre.
