What does the word chorus mean in a song?

The chorus of a song is the part that is repeated throughout the song, usually after each verse. It is typically the most memorable part of the song and contains the main message or theme. The chorus often consists of a catchy melody and lyrics that are easy to sing along to. It is often used as a way to build up the energy of the song and create a sense of excitement and anticipation. Choruses can also serve to provide a sense of continuity and structure to a song, helping to tie the verses together and create a cohesive whole.
