<P>PROBLEM TO BE SOLVED: To provide a woodwind instrument and a rectification member capable of reducing generation of noise while setting a bore diameter of a sound hole in a small dimension, reducing the number of components and manufacturing cost, and preventing musical performance from becoming difficult. <P>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 thereof at multiple points. The rectification member 33 can rectify an air flow turbulence in the correction sound hole 20 during playing music, thereby reducing noise generated by the correction sound hole 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
