Abstract

A tempo trainer includes a plurality of lights displayed on a front display surface of a housing in the form of at least one of a line or a circle and including a center light. A beat can be set for an electronic metronome. An attack from a musical instrument can be compared with the beat using a phase comparator. The difference in phase between the beat and the attack can be determined by the phase comparator. The difference in phase (time-difference) between a beat of an electronic metronome and an attack of a musical instrument can be displayed by the plurality of lights. The plurality of lights can visually display the difference with at least one or a portion of the plurality of lights becoming lit either ahead of, at, or after a center light to indicate whether a musician operating the musical instrument is playing ahead of, at, or after the beat of the electronic metronone.
