A music box comprising a blower unit and a flute unit. Each flute in the flute unit includes a mouth and a wind inlet hole for feeding air to the mouth and the wind inlet holes for feeding air to the flute are selectively opened/closed to produce a desired melody. Further, an air outflow hole is provided in a wind trunk of the blower unit and a disk having holes for cyclically opening/closing the hole is rotatably provided. Thus the pressure of wind fed to each flute changes at a predetermined interval of time. As a member for recording a melody, the following two methods are available. One method is a disk having protrusions for pressing the key members of the flute unit and another method is a film member which opens/closes the air inlet hole of the flute unit.
