In classical music a chorus is any substantial group of performers in a play, revue, musical or opera who act more or less as one. It can also mean a work, or section of a work, performed by a chorus. Today, it is most usually used as a synonym for choir to mean a group of singers who all sing together or a piece sung by such a group, but it can also mean a group of dancers, and in Greek drama it meant a group of actors (see also: Greek chorus).

In popular music, chorus is used to mean the refrain of a song, which often sharply constrasts the verse melodically, rhythmically, and harmonically, and assumes a higher level of dynamics and activity, often with added instrumentation. Chorus form, or strophic form, is a sectional and/or additive way of structuring a piece of music based on the repetition of one formal section or block played repeatedly.
