PURPOSE: A device for playing a keyboard of a fan flute is provided to easily and accurately make sounds by jetting air to a target of a tube of a fan flute through an air jetting hole. CONSTITUTION: A key flute(100) comprises a keyboard(110), an air injecting unit(120), an air controlling unit, an air jetting unit(140), and a fan flute unit(150). The keyboard makes sounds when an operator pushes or releases keys. The air injecting unit holds air in an air storing chamber by blowing the air through a mouse piece and supplies the air to a corresponding air controlling chamber when the operator pushes the keys. The air controlling unit is connected to the keyboard and the air injecting unit and opens and closes an air controlling door in the inside of the air controlling chamber according to pushing and releasing operations of the keys, thereby controlling an air flow. The air jetting unit is connected to the air controlling unit and makes the air has flown flow along an air flowing passage and jets the air on a target of a fan flute tube through the air jetting hole set at specific jetting angle and width according to properties of the fan flute tube. The fan flute comprises semitone tubes. The semitone tubes are arranged to be touched to the air jetting unit, thereby making set sounds with the air jet through the air jetting hole. |
