<p>PROBLEM TO BE SOLVED: To easily facilitate a countermeasure even to the selection of a basic pitch or the condition of a performance environment without being affected by the variation of various conditions at the time of manufacturing by providing a supporting body to be inserted so as to be attachable and detachable into the f-shaped hole of a violin instrument and an adhered body supported by the supporting body for covering one part of the f-shaped hole. SOLUTION: A wolf tone remover 1 is provided with a supporting body 2 to be inserted so as to be attachable and detachable into an f-shaped hole H and an adhered ring 3 supported by the supporting body 2 for covering one part of the f-shaped hole H. The adhered ring 3 is decided so that a surface plate in the surrounding of a circular hole H1 can be interposed with a protruding part 40 of a leg part 4. This wolf tone remover 1 is mounted on the f-shaped hole of a violin instrument so that one part of the f-shape hole H can be covered, and the open area can be reduced, and Helmholtz resonance frequencies can be changed. Therefore, it is possible to prevent the wolf tone remover from being affected by the variation of various conditions at the time of manufacturing the instrument, and it is possible to easily facilitate a countermeasure to the selection of a basic pitch or the condition of a performance environment.</p> |
