What kind of vocal ensemble performs repertoire of musical theater?

A vocal ensemble that performs repertoire of musical theater is typically a show choir. Show choirs are known for their energetic performances that combine singing, dancing, and often theatrical elements. They focus on popular music, particularly from theatrical productions, which allows them to engage with the narrative and emotional aspects of the songs. The emphasis on choreography and visual presentation makes show choirs distinct from other types of choral groups.

Chamber choirs consist of smaller groups that focus on a wide range of choral music, often with an emphasis on more traditional or classical repertoire. Concert choirs perform a variety of genres but usually do not emphasize the theatrical aspects found in musical theater. Jazz choirs specifically focus on jazz music and often feature improvisation, which is different from the scripted and choreographed performances typical of musical theater. Hence, a show choir is uniquely suited for this type of repertoire.
