Description

The present invention relates to a ligature for a single reed woodwind instrument, and more specifically, the present invention relates to a ligature for a single reed woodwind instrument, and more specifically, it has a simple and well-designed structure that ensures excellent sound quality, is easy to install, and can suppress misalignment during performance. This invention relates to a ligature for single reed woodwind instruments that is easy to disassemble and maintain.

Traditionally, woodwind instruments such as saxophones and clarinets have been widely used not only in classical performances, but also in jazz, pop, and enka performances.
Such woodwind instruments are usually played by tightening and fixing the reed to the mouthpiece using a ligature, and amplifying the vibration sound of the reed with the instrument.
More specifically, the mouthpiece 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 on the gripper side, By forming a tip opening between the reed and the other end of the back surface, by blowing into the tip opening, the reed can vibrate up and down in a cantilever shape to generate sound.

Among woodwind instruments, mouthpieces for saxophones are made of a variety of materials such as metal, rubber, wood, and ceramics, and ligatures are also made of a variety of materials and structures, and are used depending on the musical genre such as classical or jazz. It is being
As a ligature for such a single-reed woodwind instrument, there is a type disclosed in Patent Document 1, for example.

This ligature is a ligature for tightening the reed and mouthpiece so that the reed does not move, and is made of a thin plate made of metal, such as brass, for winding the reed and mouthpiece, and the mouthpiece. A tightening part that tightens both ends of the thin plate part at a position opposite to the lead across the lead, a protrusion part that protrudes from the lead and contacts the lead at its tip, and a reinforcement part that strengthens the bending strength of the thin plate part near the protrusion part. In order to avoid contact between the reed and the thin plate part, the protruding part is provided on the surface opposite to the surface of the thin plate part on which the protruding part is provided, and from the outermost end of the protruding part in the lateral direction when viewed from the mouth side. The reinforcing material is added around the hole provided on the lead side surface of the thin plate part, and the surface of the thin plate part to which the reinforcing material is attached is formed into a substantially flat surface. The tightening section tightens both ends of the thin plate section using the screw hole, the cylindrical section, and the screw at a position facing the reed with the mouthpiece in between.
It is stated that even if the ligature is tightly tightened, the ligature does not touch the edge of the reed and can produce the desired sound. Surface contact is made in the longitudinal direction of the ligature over the entire width direction of the ligature, intentionally eliminating point contact.

However, as described in Patent Document 2 and Patent Document 3, from the viewpoint of sound quality rather than volume when playing a musical instrument, the smaller the contact area of the ligature with the reed, the better. Line contact or point contact is better.
In this regard, Patent Document 4 discloses another ligature.

This ligature includes a base part that straddles the width direction of the reed provided along the table surface of the mouthpiece and is fixed to the mouthpiece, and a pressing plate part that presses the reed against the table surface of the mouthpiece. The pressing plate part has a screw hole portion through which the screw screw portion passes through in the thickness direction, and a pair of screw holes extending in opposite directions across the hole portion. The base part has a screw hole into which the tightening screw part can be screwed, and the pressing plate part is provided in the space between the lead and the base part, and the pressing plate part is provided in the space between the lead and the base part. It is provided so that it is in surface contact with the curved front surface in the extending direction of the table surface, and when the tightening screw part is tightened against the screw hole part, the pressing plate part presses the reed against the mouthpiece. It is now possible.

In the case of this ligature, it is possible to reduce the contact area with the reed with the press plate, but since the press plate is provided in the space between the base part and the reed, that is, below the base part, the overall structure The ligature is large, bulky, and heavy, and it is inconvenient to wear it with the reed against the mouthpiece.When you want to adjust the depth of insertion of the mouthpiece into the instrument while playing, you have to hold the ligature with your fingers to insert the mouthpiece into the instrument. If the ligature is rotated in the longitudinal direction, the position at which the ligature is fixed to the reed may shift, causing problems in playing.

Furthermore, because the pressure plate is provided in a narrow space between the ligature and the reed, and the structure is complicated, the internal thread is brazed to the ligature body, making it difficult to disassemble the ligature itself. Maintenance such as disassembly and cleaning is inconvenient, and the ligature body becomes soft due to the heat generated by brazing, which can have an adverse effect on sound quality.

More specifically, the pressing plate portion 14 is provided with a hole portion 18 and has a central portion 26 that is longer than the width w1 of the base portion 12, and each of the pair of pressing portions 20 has a corresponding central portion 26. A pressing surface 24 is provided at the lower end of the leg portion 30 .
The pressing surface 24 has an arch shape in the width direction of the lead R so as to follow the curved surface of the skin portion SR of the lead R.

Regarding the pressing surface 24, the tightening screw portion 1 is adjusted according to the degree of curvature of the front surface of the skin portion SR of the lead R.
The contact area of the pressing surface 24 with respect to the front surface of the skin portion SR can be adjusted by the pressing force of the pressing plate portion 14 against the lead R due to the tightening in step 6.
More specifically, the cross section of the lead R of the pressing surface 24 in the longitudinal direction has a shape that slopes downward from the center portion 26 side to the tip portion in the longitudinal direction. More specifically, among the pair of pressing plate portions 14, the pressing surface 24 provided from the central portion 26 to the tip side has a shape that slopes downward from the central portion 26 side to the tip end portion in the longitudinal direction. The pressing surface 24 provided from the section 26 toward the musical instrument side has a shape that slopes downward from the central section 26 side toward the distal end toward the instrument side in the longitudinal direction.
In both cases, the leg portions 30 are arranged so that the longitudinal tip portion first contacts the front surface of the skin portion SR of the lead R, and as the pressing force increases, the contact portion increases from the longitudinal tip portion toward the center portion. Set the rigidity, especially the thickness.

On the other hand, the cross section of the pressing surface 24 in the width direction of the lead R has a curved shape from the center in the width direction to the tip end in the width direction. More specifically, in each of the pair of pressing plate portions 14, the pressing surface 24 of one leg portion 30 is curved from the widthwise center of the lead R to the widthwise tip portion, and The pressing surface 24 has a curved shape extending from the center in the width direction of the lead R to the tip end facing in the opposite direction in the width direction. In this case, the tip in the width direction first comes into contact with the front surface of the skin part SR of the lead R, and as the pressing force increases, the contact area increases from the tip in the width direction toward the center of the width direction of the lead R. The rigidity, especially the thickness, of the leg portion 30 is set in advance, and the curved shape of the front surface of the skin portion SR of the lead R varies depending on the type of the lead R. By adjusting the pressing force,
The contact area can be adjusted by increasing or decreasing the number of contact parts in the longitudinal and width directions, and versatility can be ensured for different types of lead R.
As described above, as shown in FIG. 16, the present ligature 10 for a single-reed woodwind instrument has a structure in which the ligature itself is has a low center of gravity, and the pressing surface 24 contacts the front surface of the skin portion SR of the lead R at two positions spaced apart in the longitudinal direction of the lead R. At each position, Each pressing surface 24 is in line contact with the front surface of the skin part SR, and the line contact area can be adjusted through the pressing force depending on the degree of tightening of the tightening screw part 16, so it is simple. Although it has a simple structure, the sound quality can be improved and adjusted.

The blank hole portion 18 is an elliptical opening whose long axis is located in the longitudinal direction of the central portion 26, and is set to a size that allows a male screw portion 54 of the tightening screw portion 16, which will be described later, to pass through.
The pair of leg portions 30 extend obliquely downward within the width direction of the lead R so as to move away from each other in the width direction of the lead R.
The base part 12 and/or the pressure plate part 14 may be lacquered on the front side, thereby making it possible to improve the sound quality, as well as the instrument itself.
The distance D in the longitudinal direction between the pair of pressing portions 20 is preferably one-third to one-half of the length of the skin portion SR on the front surface of the lead R.
The width of the central portion 26 of the pressing plate portion 14 is preferably one-third to one-half of the width of the mouthpiece MP, and the height of the U-shape, that is, the height h2 of the central portion 26 with respect to the pressing portion 20. By screwing the tightening screw portion 16 into the screw hole portion 22 of the convex portion 41, which will be explained later, the pressing surfaces 24 of each of the pair of pressing portions 20 press and fix the reed R against the table surface T of the mouthpiece MP. It may be determined according to the arch height of the base portion 12 as much as possible, but from the viewpoint of lowering the center of gravity of the entire woodwind instrument ligature 10 for single reeds and contributing to improving sound quality, it is preferable to set it as low as possible. Preferably, the length is preferably within 5 mm, and the material is preferably metal, such as brass, particularly silver.

As shown in FIG. 16, the pressing plate part 14 has a concave part 36 with an elliptical cross section on the back surface concentrically with the hole part 18, and a convex part 40 (described later) fixed to the base part 12 has a concave part. 36, the pressing plate portion 14 is fixed relative to the base portion 12 so as not to rotate relative to the base portion 12. More specifically, the upper surface of the convex portion 40 comes into contact with the annular bottom surface 37 of the concave portion 36, thereby determining the relative height of the mouthpiece MP of the pressing plate portion 14 with respect to the table surface T, and the convex portion 40 of the pressing plate portion 14, In this way, relative rotation with respect to the base portion 12 is disabled.
The relative height of the pressing plate portion 14 with respect to the table surface T of the mouthpiece MP is determined by the front surface of the skin portion SR of the reed R set on the table surface T of the mouthpiece MP by screwing with the tightening screw portion 16. It is only necessary to set it so that it can be pressed and fixed.

As a modified example, the pressing plate part 14 is provided with a blank hole part 18, and the width w1 of the base part 12 is
The pair of pressing portions 20 each have a sloped portion (not shown) extending downwardly from the entire corresponding end 28 of the central portion 26, and each of the pair of pressing portions 20 has a longer central portion 26. may extend from the entire lower end of the inclined portion, and a pressing surface 24 may be provided on the lower surface.
In this case, the pressing surface 24 has a pair of protrusions (not shown) that are spaced from each other in the width direction of the pressing plate part 14, and each of the pair of protrusions is pressed against the skin part SR of the lead R. It is also possible to form a curved surface that protrudes downward as long as the front surface does not become concave, and make point contact with the lead R via the curved surface.

As shown in FIG. 5, the tightening screw portion 16 includes a male screw portion 54 and a head portion 56 that is provided concentrically at the tip of the male screw portion 54 and can be rotated by pinching with fingers.
By tightening with the tightening screw part 16, the pressing plate part 14 between the tightening screw part 16 and the base part 12 fixed to the mouthpiece MP is attached to the base part 12 side, that is, the front surface of the reed R. The reed R is fixed against the table surface T of the mouthpiece MP. The pressing force of the pressing plate portion 14 against the lead R can be adjusted by the degree of tightening by the tightening screw portion 16.
From the viewpoint of lightweight, it is preferable that the head portion 56 is not solid but consists of an upper plate and an annular plate extending downward from the periphery of the upper plate. Therefore, it is preferable to make it easy to rotate around the longitudinal direction of the male threaded portion 54.
As shown in FIG. 8, the length l2 of the male threaded portion 54 is such that the length l2 of the male threaded portion 54 is determined until the lower surface 64 of the shank portion 62 of the male threaded portion 54 touches the upper surface of the annular protrusion 31 of the pressing plate portion 14. When tightening, it is preferable to set the lower end of the male threaded portion 54 so as not to protrude from the lower surface of the convex portion 40 as much as possible.
Further, a shank portion 62 is provided at the root of the male threaded portion 54 concentrically with the male threaded portion 54. In this case, since the sound quality changes depending on the mass of the shank portion 62, the diameter of the shank portion 62 is and/or it is better to adjust the length l1.
With the annular bottom surface 37 of the recess 36 on the lower surface of the pressing plate section 14 in contact with the upper surface of the protrusion 43 of the protrusion 40, the shank section 62 of the male thread section 54 is tightened by tightening the tightening screw section 16. The lower surface 64 of the press plate portion 14 can press and fix the reed R against the table surface T of the mouthpiece MP by contacting the upper surface of the annular protrusion 31 of the press plate portion 14.

As shown in FIG. 6, a convex portion 40 is provided to be inserted into the hole 28 of the base portion 12 from below. The protrusion 40 has a protrusion 43 having an elliptical cross section and a female screw hole 22 , and an overhang flange 41 provided at the bottom of the protrusion 43 . Pass the convex portion 40 through the hole 28 from below the base portion 12 until it touches the circumferential surface, the upper surface of the protruding portion 43 protrudes from the outer circumferential surface of the base portion 12, and insert the concave portion 36 on the lower surface of the pressing plate portion 14 into the protruding portion 43. In the fitted state, the screw holes 22 are vertically aligned with the blank holes 18 of the pressing plate part 14, and screwed into the screw holes 22 through the blank holes 18 with the tightening screws 16 from above. It makes it possible. The concave portion 36 and the convex portion 40 have an elliptical shape with the long axis facing in the width direction of the mouthpiece MP, and by fitting the convex portion 40 into the concave portion 36, the pressing plate portion 14 is moved relative to the base portion 12. It is made to not rotate.
In this case, as shown in FIG. 1, the convex part 40 having an elliptical cross section is passed through the elliptical opening 22 from below the annular base part 12 until the overhanging flange part 41 contacts the inner peripheral surface of the annular base part 12, and the annular upper surface By projecting from the outer circumferential surface of the annular base portion 12, the convex portion 40 can be set to be non-rotatable relative to the annular base portion 12. By fitting the concave portion 36 on the lower surface of the pressing plate portion 14 into the protruding portion 43, it is possible to similarly set the pressing plate portion 14 so that it cannot rotate relative to the annular base portion 12, and the lead R can be set to the position of the mouse. With the piece MP positioned on the table surface T, by screwing the male threaded portion 54 of the tightening screw portion 16 into the screw hole portion 22 of the convex portion 40, the lead R is directed toward the table surface T by the pressing surface 24. It is possible to press and fix.
As described above, in the case of the annular base portion 12, even if the annular base portion 12 itself does not have a screw hole portion in the thickness direction, the convex portion 40 having the screw hole portion can be attached to the annular base portion by brazing as in the conventional method. 12, and the adverse effect on sound quality caused by heating during brazing can be avoided.
Note that when the overhanging flange portion 41 of the convex portion 40 contacts the inner circumferential surface of the annular base portion 12, it is preferable that the overhanging flange portion 41 not protrude from the inner circumferential surface and be flush with the inner circumferential surface. In relation to this, if it is permissible, a recess having a shape complementary to the overhanging flange portion 41 may be provided on the inner circumferential surface of the annular base portion 12 by the thickness of the overhanging flange portion 41.

As shown in FIG. 7, an elastic ring 17 is interposed between the pressing plate part 14 and the tightening screw part 16. More specifically, the elastic ring 17 is annular with a circular opening 19, and is pressed against the pressing plate part 14 by passing the male screw part 54 through the circular opening 19 and tightening the tightening screw part 16. By collapsing in the direction, the pressing force of the pressing plate part 14 is reinforced by the repulsive force. It is possible to change the sound quality by selecting the rigidity of the elastic ring 17. For example, if it is made of rubber with low rigidity, it will have a soft tone, and if it is made of a spring washer with high rigidity, it will have a bright edge but a slightly thinner sound. Become. Note that the elastic ring 17 is an option, and in that case, the lower surface 64 of the shank portion 62 of the male threaded portion 54 directly contacts the upper surface of the annular protrusion 31 of the pressing plate portion 14.
Note that when the convex portion 41 is passed through the hollow hole 28 of the annular ring 12 by tightening the tightening screw portion 16, and when the concave portion 36 of the pressing plate portion 14 is fitted into the protrusion 43 of the convex portion 41, both , some lateral play is allowed.

As shown in FIG. 13, as a modified example of the annular base portion 12, it is made of pure silver, and an irregular pattern PN consisting of multifaceted portions 46 each having a flat or curved surface is formed in an annular shape on the outer circumferential side surface 38. The multifaceted portions 46 adjacent to each other may be provided in an uneven shape so as not to be included within the same cylindrical surface concentric with the mouthpiece MP. The difference in height of the unevenness 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 MP due to the increase in the surface area of the outer peripheral side surface 16. The irregular pattern PN may be a hammered pattern or a satin pattern.
Each of the polygonal parts 46 forms a polygon on a curved surface, and the polygonal parts 46 adjacent to each other may share the sides 17 of the polygon. In the multifaceted portion 46, the polygons have different sizes and shapes to form an irregular pattern PN.

Such an annular base portion 12 is preferably formed by forging a pure silver flat plate with a thickness of 1 mm to 3 mm to form a multifaceted portion 46 forming an irregular pattern PN, and then bending the pure silver flat plate into an annular shape.

As a result, the weak strength due to the thin structure of pure silver is reinforced by forging, and as a result of forging, a hammered pattern is formed from the multifaceted parts 46, and the shape and size of each multifaceted part 46 are non-uniform. A certain irregular pattern is obtained, which is similar to the unevenness formed on the inner circumferential surface of a Japanese drum's resonance box, producing an acoustic effect, and furthermore, the irregular pattern is created by the light of a light, especially in a dark room. The multifaceted portion 46 of the PN reflects glitteringly in various directions, making it possible to improve the design of the woodwind instrument to which the mouthpiece MP is attached.
The width w1 of the pure silver annular base portion 12 is set to 80% or more of the width W of the lead R. 80%
Below, it is difficult to obtain the sound quality effect through the mouthpiece MP.
The thickness t1 of the pure silver annular base portion 12 is set according to the width W of the lead R, and is set to 3 mm or less. If it is 3 mm or more, it is difficult to obtain the sound quality improvement effect of the present invention through the mouthpiece MP.
When securing the width w1 and the thickness t1 of the sterling silver annular base portion 12, the size of the polygons may be increased in the multifaceted portion 46 to lower the density of the irregular pattern PN. It is preferable to make the thickness t1 as thin as possible within a range where the strength of the ligature 10 can be ensured.

As a further modification, the multifaceted portion 46 forming the irregular pattern PN of the pure silver annular base portion 12 may be formed in one strip in the width direction and in a row in a horizontal stripe shape in the circumferential direction.

The sound quality improving portion is an unevenness on the outer circumferential side surface 16 of the metal or rubber mouthpiece MP for saxophone, and is constituted by an annular multifaceted portion 46 each consisting of a flat or curved surface on the outer circumferential side surface of the mouthpiece MP. As the irregular pattern PN, it is preferable to form an uneven pattern that is not concentric with the cylindrical portion of the mouthpiece MP, and this may be formed by grinding. The entire surface of such an annular base portion 12 made of pure silver may be plated with gold, thereby making it possible to bring out the complex warm tone characteristic of gold material.
In addition, in the sterling silver annular base part 12 as such a sound quality improving body, by making the material particularly sterling silver, since silver does not have a specific natural frequency compared to gold and copper, This has the effect of making the effect of concavities and convexities conspicuous due to the irregular pattern PN formed by the multifaceted portions 46 provided on the outer surface.

As a further modification, as shown in FIG. 14, the present invention may be applied to a mouthpiece MP equipped with a sound quality improving body called a pure silver shank ring. More specifically, the sound quality improving body is a sterling silver shank ring, the multifaceted part 46 is formed by forging a sterling silver flat plate with a thickness of 0.5 mm to 1.5 mm, and the sterling silver flat plate is bent into an annular shape to form a mouthpiece. The sterling silver shank ring is tightly fitted to the end 60 on the opposite side of the tip opening O, and the sterling silver shank ring also has an uneven pattern PN on its outer circumferential surface to prevent various vibrations. Since it responds dispersively to the number, it has the effect of richness of the sound including multiple overtones, as well as the resonance and extension of the sound.By using both the sterling silver base part and the sterling silver shank ring, this effect is achieved. The improvements in design are even more noticeable.

As described above, using the annular base part 12 made of pure silver with an uneven surface, the lead R is adjusted against the mouthpiece MP.
When the cylindrical portion of the mouthpiece MP is tightened and fixed, the irregular pattern PN formed by the multifaceted portions 46, each of which is a flat or curved surface, is formed on the outer circumferential surface of the mouthpiece MP in an annular manner. is formed, so when you blow into the mouthpiece MP through the tip opening to produce a sound, it is possible to smoothly and continuously change from a silent state to a sound state. Due to the increased surface area of the side surface and the irregular pattern PN, the specific frequency of the reed R does not resonate and only that sound is emphasized. Since it responds to various vibration frequencies in a dispersive manner, the sound is rich, including multiple overtones, and has excellent resonance and extension, and even when it fades out from a sound state, it produces a smooth and continuous sound. It is possible to create a silent state, and even inexperienced performers who have not established the embouchure, which is important for controlling the sound, can easily manipulate the sound, allowing them to perform with high musicality. Not only is this possible, but it is also possible to improve the design of the woodwind instrument to which the mouthpiece MP is attached, since the multifaceted portions 46 of the irregular pattern PN reflect light in various directions, especially in a dark room. It is possible.
In addition, in the case of the sterling silver annular base part 12 having such an irregular pattern PN, when attaching the reed R to the table surface T of the mouthpiece MP using the single reed woodwind instrument ligature 10, the sterling silver annular base part 12 The inner circumferential surface of the mouthpiece MP contacts the mouthpiece MP at a position diametrically opposite to the table surface T of the mouthpiece MP, but in addition, the inner circumferential surface of the sterling silver annular base portion 12 is positioned on the table surface T of the mouthpiece MP. By directly hitting the upper corners of both edge portions E in the width direction of the reed R, it is possible to further enhance this sound quality improvement effect.

According to the single-reed woodwind instrument ligature 10 having the above configuration, the base portion 12 that is fixed to the mouthpiece MP straddles the width direction of the reed R provided along the table surface T of the mouthpiece MP. On the other hand, the pressing plate part 14 is positioned above the base part 12, the tightening screw part 16 is passed through the blank hole part 18 of the pressing plate part 14, and the screw part 14 is tightened to the screw hole part 22 of the base part 12. Therefore, the pressing plate portion 14 can press the reed R against the mouthpiece MP via the pair of pressing portions 20, and the pair of pressing portions 20 can press the reed R against the mouthpiece MP.
By extending in opposite directions with 8 in between, it is possible to press the reed R from directly above the table surface T of the mouthpiece MP at two locations spaced apart in the longitudinal direction of the table surface T. Therefore, excellent sound quality can be ensured, and the pressing plate part 14 is located above the base part 12 so as to straddle the width w1 of the base part 12 from above along the extending direction of the table surface T. Because it is provided, it has a simple and well-designed structure, and it is easy to attach the ligature 10 to the mouthpiece MP.For example, it is useful for adjusting the insertion depth of the mouthpiece MP into the instrument body during performance. , when holding the ligature 10 for a single-reed woodwind instrument with one hand and rotating the mouthpiece MP relative to the instrument body around the longitudinal direction, it is possible to suppress the displacement of the reed R relative to the mouthpiece MP during performance. To provide a ligature 10 in which a base part 12, a pressing plate part 14, and a tightening screw part 16 can be disassembled separately by simply loosening the tightening screw part 16, and which has excellent disassembly and maintainability. is possible.
