A click track
is used for maintaining a precise tempo
. In animation
, the click track is used by the musical conductor
during a recording session
so the music
is timed perfectly with the image
s. For musicians recording an album
in a studio
, it is used (normally by the drummer
) to maintain proper timing during the song. Most drummers vary their timing slightly, and the click track is used to help alleviate tempo shift
ing. An example of this can be heard on early REM
albums. The drum
mer has timing problems, and later he learned to use a click track to keep the proper pace for later albums. The original drummer for Marilyn Manson
was replaced because he could not play to a click track.
The clicks are generated by an electronic device or a metronome. Some drummers use a flashing light-emitting diode (LED) instead of an audible click track.
