Abstract
Abstract An electronic musical instrument capable of reporting a sound level and a tempo to be set. When a particular sound level or a particular tempo is selected and set, a click having a particular pitch matching the sound level or the tempo is generated to allow the user to recognize the sound level or the tempo on the basis of the pitch of the click. The instrument has a right and a left loudspeaker and, when the sound level is high or the tempo is fast, produces louder sound from one of the loudspeakers while, when the sound level is low or the tempo is slow, producing louder sound from the other loudspeaker.
