Abstract
An electronic metronome with an oscillator for producing a signal of predetermined frequency and a variable divider connected to the oscillator for variably dividing the signal to a signal of lower frequency equal to that of a tempo sound to be obtained. A tempo sound generator is connected to the variable divider and is responsive thereto for generating the tempo sound to be obtained. Apparatus is provided for audibly and/or optically displaying the thusly obtained tempo sound. The electronic metronome is capable of effecting audible and visual display of a down-beat sound and medial-beat sound or any combination thereof besides the tempo sound.
