Which term signifies the end of a piece in music?

The term that signifies the end of a piece in music is "fine." This Italian word translates to "end," and it is commonly used in scores to indicate where the music concludes. Typically, "fine" is seen at the ending section of a piece after repeating or thematic material, serving as a clear directive for performers.

Although "coda" also indicates an ending, it refers to a specific concluding passage that is usually distinct from the main themes of the music. "Al fine" means to go to the point marked "fine," suggesting a return to where the conclusion lies, which emphasizes that it directs performers to reach the ending rather than serving as the term for the end itself. "Tacet," on the other hand, instructs a performer not to play during a section, which does not relate to marking the conclusion of a piece. Therefore, "fine" is the most straightforward and accurate term for denoting the end of a piece of music.
