the.com/postlude

means A concluding piece of music or action that comes after the main event is over, often played to organ recitals, worship services, or stories as a closing flourish.

from Built in the 19th century by slapping the Latin prefix 'post-' (after) onto the back end of 'prelude,' which itself traces to Latin 'praeludere' — to play beforehand, a warm-up. Once 'prelude' existed as the thing before, 'postlude' was coined as its mirror-image opposite: tidy, symmetrical, and a little bit of an afterthought by design.
