An electronic metronome has a casing including a display portion for displaying a numerical value of a tempo, a sound emitting device for emitting a sound representing the tempo, a vibration device for generating a vibration representing the tempo, and a vibration level adjusting device for adjusting the stregth of the vibratrion. The vibration is used for notifying a tempo to a user, whereby the user can master a good sense of tempo efficiently without being affected by the surrounding environment. The electronic metronome prevents the phenomenon that if a user performs a musical piece specified with a slow tempo immediately after performing a musical piece specified with a fast tempo, the user may perform the piece at a faster tempo than the originally intended slow tempo.
