PROBLEM TO BE SOLVED: To provide a keyboard harmonica capable of adjusting a tone, without complicating the structure.SOLUTION: The opening ratio of a valve packing 40 of a keyboard harmonica 1 for a middle sound range SA2 and a high sound range SA3 is smaller than 1. By this, in a whistle room 10 corresponding to the middle sound range SA2 and the high sound range SA3, since the air flow hits the bulb packing 40 and an air flow route R is changed, the tones of the sounds of the middle sound range SA2 and the high sound range SA3 are adjusted to be mellow. Further, since the shape of an opening 41 of the bulb packing 40 is changed, the tone can be adjusted without complicating the structure.SELECTED DRAWING: Figure 3
