Click

A click in film music is a metronomic tempo that has been specifically calibrated to match the number of frames, and eighth of frames, between beats (or beats per minute). It is by matching the precise tempo of a click track to the number of seconds and frames between hits that a composer is able to sync a piece of music to multiple edited cues and actions in a film.

In the past, composers used click books, large compendiums of timing tables, to manually calculate every cue of a score to match the movie for which it was written. These days, precise timing is achieved through the use of computers and software such as the Auricle program.
