Clarinet ensemble (often called a clarinet choir when it includes the full family) is a chamber/wind format built entirely from clarinets across the instrument’s range—typically E♭ (piccolo), B♭/A soprano, basset horn or alto clarinet, bass clarinet, and contrabass clarinet.
Its signature sound is a warm, vocal, organ-like blend with exceptional agility and homogeneous timbre. Repertoire spans arrangements of orchestral and operatic music, wind-band literature refashioned for clarinets, jazz-tinged originals, and a growing body of contemporary works written specifically for clarinet quartet/choir.
Beyond concert stages, clarinet ensembles serve as pedagogical laboratories in universities and festivals, sharpening players’ blend, intonation, articulation alignment, and low-register support while showcasing the clarinet’s full coloristic spectrum.

The clarinet ensemble coalesced in the early 20th century as clarinetists and educators explored stacked voicings of the clarinet family. The format drew on the long-established European classical and chamber traditions, but its consolidation into choirs/quartets was catalyzed by pedagogues and band programs—especially in the United States—who recognized how well the family’s matched timbres could emulate choral/organ textures.
After World War II, university studios, military bands, and civic groups formalized clarinet choirs and quartets. Composers began contributing original works and educational suites, while arrangers adapted symphonic and operatic staples. By mid-century, the clarinet quartet/choir was a staple at conservatories and music festivals, with parts spanning E♭ to contrabass to create SATB-like voicings.
In the late 20th and 21st centuries, the format spread worldwide. Professional quartets and large choirs commissioned new music ranging from neoclassical and minimalist idioms to jazz-inflected concert pieces. Contemporary composers exploit extended techniques (slap tongue, flutter tongue, multiphonics) and bass/contrabass clarinets for cinematic depth, while educational ensembles keep the tradition vibrant through arrangements that introduce players to blend, balance, and ensemble discipline.
Today, clarinet ensembles appear in concert halls, universities, festivals, and community settings. Their repertoire spans Baroque transcriptions, Romantic overtures, wind-band classics reimagined, and brand-new works, cementing the ensemble as both a pedagogical cornerstone and a distinctive concert genre.
