To provide a display control device that allows a user to easily keep the beats.SOLUTION: A display control device comprises a control unit that controls a light source unit. The control unit set one tempo from among a plurality of tempos, and changes, according to the timing of a first beat of the set tempo, a display form of light emitted from the light source unit and cast on a display unit from a third display form to a first display form. A first period during which the display form of the cast light changes between the third display form and the first display form has a constant length irrespective of the set tempo. The constant length is a length less than one beat of the fastest tempo of the tempos that can be set.SELECTED DRAWING: Figure 5

An in-ear monitor system has earpieces with haptic metronome actuators. Synchronized metronome vibration pulses, which pose no audible interference to audio monitoring, stimulate the user's ear and or ear canal. A sound engineer or technician from a control console selects or programs the synchronized metronome timing sequence and the sequence is multicast to one or more receiver body packs worn by the performer in the group. The timing sequence can alternatively be selected in response to audio commands spoken by a user wearing the in-ear monitor, or can be based on a beat sensor.
