Definitions

  • the present invention relates to a sound quality improvement unit or sound quality improvement body for a mouthpiece for a woodwind instrument, and more specifically, to a sound quality improvement unit or sound quality improvement body for a mouthpiece for a woodwind instrument that allows even an inexperienced player to easily manipulate the sound while improving the richness of the sound, enabling highly musical performances, and also improving the design of the woodwind instrument.
  • woodwind instruments such as saxophones and clarinets have been widely used not only in classical music performances, but also in jazz, pop and enka performances.
  • Such woodwind instruments are usually played by fastening the reed to the mouthpiece with a ligature, and the sound of the reed's vibrations is amplified by the instrument.
  • the mouthpiece has a table surface which abuts and fixes one end of the underside of the reed, and a facing which extends at an angle from the table surface towards the tip, and a tip opening is formed between the other end of the underside of the reed on the gripping side, allowing the reed to vibrate up and down like a cantilever beam to produce sound.
  • saxophone mouthpieces are made from a variety of materials, including metal, rubber, wood, and ceramic, and are used differently depending on the musical genre, such as classical or jazz.
  • Saxophone mouthpieces in particular, use ligatures made of silver-plated brass or pure silver, which are used because they produce a unique tone compared to ligatures that are not made of pure silver.
  • silver-plated or pure silver ligatures have the following problems or areas requiring improvement.
  • the ligature is weak due to its thin structure. Since it is made of pure silver, it is easily deformed, and repeated removal and tightening of the ligature from the mouthpiece makes it difficult to achieve a tight fit to the mouthpiece. If the ligature is tightened too much, it may break.
  • the object of the present invention is to provide a sound quality improvement unit or body for a mouthpiece for a woodwind instrument that allows even an inexperienced player to easily manipulate the sound while improving the richness of the sound, enabling highly musical performances, and also improving the design of the woodwind instrument.
  • the sound quality improving portion or sound quality improving body for a mouthpiece for a woodwind instrument of the present invention is A sound quality improving part or sound quality improving body for a woodwind instrument mouthpiece, which has a table surface that abuts and fixes one end side of the back surface of the reed, and a facing that extends obliquely from the table surface toward the tip, and which is provided in an annular shape around the longitudinal direction of the outer peripheral side of the mouthpiece for a woodwind instrument mouthpiece, the mouthpiece having a tip opening formed between the table surface and the other end of the back surface at the gripping portion side, thereby allowing the reed to vibrate up and down like a cantilever beam to produce sound,
  • An irregular pattern consisting of multiple facets, each of which is flat or curved, is formed in a ring shape on the outer peripheral side surface, and adjacent multiple facets are arranged in an uneven manner so as not to be contained within the same cylindrical surface concentric with the mouthpiece.
  • an irregular pattern is formed on the outer peripheral side of the mouthpiece, each of which is made up of a multi-faceted portion having a flat or curved surface, forming a concave-convex shape that is not concentric with the cylindrical portion of the mouthpiece. Therefore, when air is blown into the mouthpiece through the tip opening to produce sound, it is possible to smoothly and continuously go from a silent state to a sounding state.
  • the sound does not resonate with a specific frequency of the reed and only that sound is emphasized, but rather the sound of the inner peripheral surface of the resonance box of the Japanese drum is emphasized.
  • the uneven shape responds to various vibration frequencies in a dispersed manner, resulting in a rich sound that includes multiple harmonics, as well as excellent resonance and sustain. It is also possible to fade out from a sound state to a silent state smoothly and continuously. In general, even inexperienced players who have not yet established an embouchure, which is important for controlling the sound, can easily manipulate the sound, allowing for highly musical performances.
  • the irregularly shaped multifaceted surface reflects the light of the light in various directions, particularly in a dark indoor environment, improving the design of the woodwind instrument on which the mouthpiece is attached.
  • the irregular pattern may also be a hammered pattern. Furthermore, the irregular pattern may be a matte pattern. Furthermore, it is preferable that the difference in height between the projections and recesses is set to 0.1 mm or more.
  • each of the polyhedral portions preferably forms a polygon on the curved surface, and adjacent polyhedral portions preferably share a side of the polygon.
  • the sound quality improving portion may also be an uneven surface on the outer periphery of a metal or rubber saxophone mouthpiece, and may be formed by grinding.
  • the sound quality improving body may be a tightening-type pure silver ligature, with opposing screw holes at each end and a metal screw-in portion that can be screwed into the opposing screw holes, and the multi-faceted portion that forms an irregular pattern may be formed by forging a pure silver plate with a thickness of 1 to 3 mm, and then bending the pure silver plate into a ring shape.
  • the width of the pure silver ligature be set to 80% or more of the lateral width of the reed.
  • the thickness of the pure silver ligature is set according to the width of the reed and is preferably set to 3 mm or less.
  • the multi-faceted portion forming the irregular pattern of the pure silver ligature may be formed as a single line in the width direction and connected in horizontal stripes in the circumferential direction.
  • the sound quality improving body may be a pure silver shank ring, in which a multi-sided portion is formed by forging a pure silver plate having a thickness of 0.5 mm to 1.5 mm, the pure silver plate is bent into a ring shape, and then the ring is press-fitted into the end opposite the tip opening of the mouthpiece.
  • the mouthpiece may be a metal or rubber mouthpiece for a soprano, alto, tenor, or baritone saxophone.
  • the entire surface of the pure silver ligature may be gold plated, and the entire surface of the pure silver shank ring may be gold plated.
  • the mouthpiece 10 has a table surface 26 that abuts and fixes one end A of the back surface of the reed R, and a facing 22 that extends obliquely from the table surface 26 toward the tip 20, and a tip opening O is formed between the other end B of the back surface on the side of the mouthpiece 10, so that the reed R can be vibrated up and down like a cantilever to produce sound.
  • the sound quality improving portion or sound quality improving body of the present invention is provided in an annular shape around the longitudinal direction of the mouthpiece 10 with respect to the outer peripheral side surface 16 of the mouthpiece 10.
  • the mouthpiece 10 is a metal or rubber mouthpiece 10 for soprano saxophone, alto saxophone, tenor saxophone, or baritone saxophone.
  • An irregular pattern consisting of polyhedral portions 13 each having a flat or curved surface is formed in an annular shape on the outer peripheral side surface 16, and adjacent polyhedral portions 13 are provided in an irregular shape so as not to be contained within the same cylindrical surface concentric with the mouthpiece 10.
  • the difference in height of the irregularities is set to 0.1 mm or more. If it is less than 0.1 mm, it is difficult to obtain the sound quality improvement effect of the present invention through the mouthpiece 10 due to the increase in the surface area of the outer peripheral side surface 16.
  • the irregular pattern may be a hammered pattern or a matte pattern.
  • Each of the polyhedral portions 13 may form a polygon on the curved surface, and adjacent polyhedral portions 13 may share a side 17 of the polygon. In the polyhedral portions 13, the sizes and shapes of the polygons are different, forming an irregular pattern.
  • the sound quality improver is a tightening type pure silver ligature 100, which has opposing screw holes 109 at each of both ends 105, 107, and a metal screw-in portion 108 that can be screwed into the opposing screw holes 109.
  • a polyhedral portion 13 having an irregular pattern is formed by forging a pure silver flat plate having a thickness of 1 to 3 mm, and the pure silver flat plate is bent into a ring shape.
  • the thin pure silver structure has a weak strength which is a drawback that it is weaker, and as a result of the forging, a hammered pattern made up of multiple facets is obtained, with each facet having an irregular shape and size.
  • the width w of the pure silver ligature 100 is set to be 80% or more of the width W of the reed R. If it is less than 80%, it is difficult to obtain a sound quality effect through the mouthpiece 10.
  • the thickness t of the pure silver ligature 100 is set according to the width W of the reed R, and is set to 3 mm or less.
  • the size of the polygon in the multi-faceted portion 13 may be increased to reduce the density of the irregular pattern, and it is preferable to make the thickness t as thin as possible within the range in which the strength of the ligature can be secured.
  • a thick booster 114 with a tapered hole 116 is provided on one end of the metal screw-in part 108, and is configured to be screwed in by pinching its outer periphery with fingers, and is designed to increase the resistance when sounding compared to a normal screw-in part, contributing to improving sound quality.
  • This is an application of the thick booster applied to the screw-in part used to attach the neck part to the body of a saxophone to a ligature.
  • the multi-faceted portion 13 forming the irregular pattern of the pure silver ligature 100 may be formed as a single stripe in the width direction and connected in horizontal stripes in the circumferential direction.
  • the sound quality improver is a pure silver shank ring 200, in which a multi-faceted portion 13 is formed by forging a pure silver plate 0.5 to 1.5 mm thick, which is then bent into a ring shape and tightly fitted into the end opposite the tip opening O of the mouthpiece 10.
  • the pure silver shank ring 200 also has an irregular, uneven pattern on its outer surface, which responds in a dispersed manner to various vibration frequencies, resulting in a rich sound that includes multiple overtones, as well as an excellent resonance or sense of extension.
  • the sound quality improving portion may be formed by grinding the outer peripheral side surface 16 of the metal or rubber saxophone mouthpiece 10, as long as the irregular pattern formed on the outer peripheral side surface of the mouthpiece is annular and composed of multiple facets, each of which is flat or curved, and is not concentric with the cylindrical portion of the mouthpiece.
  • the entire surface of such a pure silver ligature 100 and/or pure silver shank ring 200 may be gold plated, thereby bringing out the complex, warm tone characteristic of gold.
  • the pure silver ligature 100 and pure silver shank ring 200 as sound quality improvers by using pure silver as the material in particular, the effect of accentuating the unevenness caused by the irregular pattern formed by the multi-faceted portion on the outer surface is achieved, since silver does not have a specific natural frequency compared to gold and copper.
