A chorus is a group of singers who perform together, often in harmony, to enhance a song or piece of music. In many styles, such as pop, rock, or musical theater, the chorus provides a catchy and memorable part that listeners can easily sing along to. It usually repeats throughout the song, creating a sense of familiarity and excitement. In addition to music, the term "chorus" can also refer to a section of a poem or play where multiple characters speak or sing together. This technique adds depth and emotion, allowing the audience to feel the collective voice of the characters, much like a musical chorus does for a song.
