* Finale: This is the most common term, especially for concerts, musicals, and plays. It refers to the final part of the performance, often featuring a grand finale song or scene.
* Encore: This refers to a performance beyond the planned program, often requested by the audience. It's usually a single song or a brief performance.
* Outro: This is a more general term for the closing part of a performance or piece of music. It can be a specific section or a gradual fade-out.
* Last Act: This is simply the final act of a multi-act performance, like a play or opera.
It's worth noting that in some cases, the "closing act" might not refer to a specific act but rather the entire final performance of a tour or event.
