The word "coda" refers to a concluding section or phase of a piece of work, especially in music or literature. It serves to wrap up the narrative or musical themes presented earlier, providing closure or a final resolution. In broader terms, it can also refer to any concluding part of an argument or discussion.
The word "coda" originates from the Italian word "coda," which means "tail." It was adopted into music terminology in the mid-18th century to denote the concluding passage of a musical composition.
