A written click track is a method of writing bars of music in consistent time values (i.e. 4 beats in :02⅔ seconds) to establish a constant tempo in lieu of a metronome value (e.g. 88 Bpm). A composer would use a written click if they planned to conduct live performers. When using other methods such as a metronome, the conductor has a perfectly spaced click playing in his ear to which he conducts. This can yield stiff and lifeless performances in slower more expressive cues. One can convert a standard BPM value to a written click where X represents the number of beats per bar, and W represents time in seconds, by using the following equation:
