PROBLEM TO BE SOLVED: To provide an inexpensive metronome provided with a baton display function. SOLUTION: An inexpensive baton display instrument comprises: a downbeat notice line which displays movement of a baton upon the notice of the downbeat and in which a prescribed number of display elements are arranged at intervals so as to be shifted from dense at its upper end to sparse at its lower end on one line vertically extended on an indication plane; a first upbeat notice line which displays the movement of the baton upon the notice of upbeat, which is branched from shared display elements that are positioned at a lower end of the downbeat notice line, and in which display elements fewer than the prescribed number are arranged at intervals so as to be shifted from dense at its upper end to sparse at its lower end in one row; and a second upbeat notice line which displays the movement of the baton upon the notice of upbeat and which is constituted of the same number of display elements as the first upbeat notice line on the downbeat notice line.
