Other forms: ensembles
An ensemble is a group of musicians, dancers, or actors who perform together, like an ensemble which has been playing music together for several years.
Ensemble comes from the Middle French word ensemblée, which means "together, at the same time." Groups of people who perform at the same time are ensembles, so are things that are put together. A collection of short stories or artwork can be an ensemble, but you don't have to be a writer or artist to be complimented on your ensemble — the outfit you are wearing.
