Abstract
A woodwind instrument such as a clarinet includes a main tube including an upper tube and a lower tube and a correcting tone hole used solely for interval correction is formed in the lower tube. An airflow adjuster is installed in the correcting tone hole. The airflow adjuster is formed in an M shape by bending a film member at three positions. The airflow adjuster can properly arrange a turbulent airflow in the correction tone hole during performance and can reduce undesired sound generated from the correcting tone hole.
