PROBLEM TO BE SOLVED: To provide a sound hole of a woodwind instrument capable of reducing generation of noise while setting a bore diameter of the sound hole in a small dimension.SOLUTION: A woodwind instrument which is a Boehm B-flat clarinet comprises a main tube including an upper tube and a lower tube, and a correction sound hole 20 being used only in musical interval correction is formed in the lower tube. A rectification member 33 is provided inside the correction sound hole 20. The rectification member 33 is formed in an M-shape by folding a film member at a plurality of points. The rectification member 33 can rectify an air flow turbulence in the correction sound hole 20 during performance, thereby noise generated by the correction sound hole 20 can be reduced.SELECTED DRAWING: Figure 2 |
