Plural of chorus; multiple groups of singers or the repeated sections in songs where the main melody is sung together.
Regular English plural using '-es' on 'chorus' (from Greek 'choros' meaning a group of dancers and singers). The word retained its plural complexity from the original Greek formation.
The structure of modern pop songs inherits directly from ancient Greek theater—the chorus was the part that repeated and united the audience, which is exactly why catchy choruses in songs today are designed to be memorable and singable by everyone, not just the lead vocalist.
