A circuit splitter is in operative communication with the metronome for multiplying the light signals. A plurality of individual light emitting components are in operative communication with the circuit splitter, the light emitting components being mounted to individual components associated with the drum kit to simultaneously display the flashing pattern corresponding to the multiplied light output signals at locations visible to a user of the drum kit. A plurality of cables extend between the circuit splitter and respective light emitting components. The light emitting components can each further include a different color in order to provide enhanced visibility in various stage lighting situations. A power supply communicates the metronome, including any of a battery or a 9V power outlet plug. ## Claims ### Claim 1 A visual metronome for use with a drum kit, comprising: a metronome generating a first audio input signal indicative of a series of audio clicks at a predetermined frequency and duration;
