Abstract: The present disclosure relates to a keypad structure for woodwind instrument tone holes, and more particularly, to a keypad structure for woodwind tones which improves the adhesion of a keypad connected to a tone hole tube in which the tone hole is formed in the woodwind instrument, prevents the sound from being exposed to the outside through the tone hole tube and the pad, and can generate excellent resonance so that the resonance of a desired sound can be constantly generated through the closed keypad.

Abstract: Disclosed herein is a method of manufacturing a mouthpiece for a wind instrument. The method of manufacturing a mouthpiece for a wind instrument includes the steps of: pulverizing a first material made of a synthetic resin material and a second material made of a mineral material; mixing the first and second materials at a predetermined ratio; melting the mixed materials and continuously extruding a primarily shaped product having a uniform sectional shape; cutting the extruded primarily shaped product into cut primarily shaped products at predetermined intervals; and forming secondarily shaped products by machining the cut primarily shaped products into mouthpiece shapes.
