A refrain is a repeated line or group of lines in a song or poem, often serving as a thematic anchor for the piece. It creates a sense of familiarity and unity, reinforcing the emotional or narrative core of the work. In compositions like the simple rondo form, the refrain is typically associated with the recurring 'A' section, allowing composers to establish a recognizable motif that contrasts with the varying sections that follow.
