Abstract

PROBLEM TO BE SOLVED: To improve the configuration of a bottleneck bar to be used for playing the guitar.SOLUTION: The cylindrical shape is modified into a triangular cylinder, with sides of its circumference being made into gentle curves, and a glass bar, a metal bar and a bar made of beef bones are attached on the triangular cylinder so as to be used as projections touching chords. In parallel with each of those projections, a sound deadening projection is attached at a spacing. When playing, a player inserts his index finger into a cavity and makes the two projections touch a chord at the same time. The player does not need to use his index finger to mute disturbing noise. Furthermore, he can play in a better way than ever by using his fingers other than the index finger to press chords. The player can achieve an accurate pitch because he can visually recognize the projections. Three different tones can be achieved by attaching bars of different materials on the three sides of the triangular cylinder of the main body. Due to a triangular cylindrical shape and the bars used as projections, the bottleneck does not roll even when it is placed sideways.

Description

The present invention relates to a shape of a bottleneck bar used for playing a guitar.

The shape of a bottleneck bar used for playing a conventional guitar is as shown in FIG. 2, with a glass tube or a metal tube placed on one of the fingers other than the thumb and forefinger of the hand pushing the guitar string. Attached and used by lightly pressing and fixing with other fingers.

In addition to metal and glass, plastics such as acrylic, cow bones, lead pipes, and even small medicine bottles are all used by inserting a finger into a cylindrical inner cavity. Because different materials have different timbres, performers use them according to their preferences, composition of music, and ease of handling.

Both of them realize a playing method with a unique pitch that is different from the exact pitch obtained by pressing a finger. While the finger string presses the string against the fixed fret to determine the pitch, the bottleneck bar does not rely on the fixed fret by letting the arc on the outer circumference of the bar lightly touch the string. Realize a free pitch.

In addition, by sliding the bottleneck bar, the pitch can be continuously raised and lowered like a portamento performance by a stringed instrument such as a violin, and vibrato is easy.

In the prior art, one point on the outer periphery of the cylindrical shape is in contact with the string to determine the pitch. Therefore, the outer surface is required to be a curved surface without unevenness. In addition, because it rubs against a steel steel string, printing, stickers and stickers cannot be applied to the bottleneck bar.

However, according to the above technique, in addition to the finger that usually wears the bottleneck bar, the finger that is lighter than the pitch that the bottleneck bar touches the string lightly touches the string and makes noise. Must be muted. The reason is that the vibration of the string stretched to the left and right is physically generated on both sides of the bottleneck bar, and the vibration on the left side of the bottleneck bar becomes noise.

This problem occurs mainly in acoustic guitars. The occurrence of vibrations on both the left and right sides is unavoidable because they are physically and naturally generated by striking. In general, when a right-handed guitarist performs, the sound of the right vibration among the left and right vibrations of the string that the bottleneck bar contacts is a sound that is required for performance. The sound generated by the left vibration on the opposite side becomes unpleasant noise. Since acoustic guitar amplifies string vibration by both the guitar body and neck, it must always be muted during performance.

When the bottleneck bar is used with an electric guitar, the left and right vibrations occur in the same way, but the microphone of the electric guitar is always located on the right side of the bottleneck bar, and only the right side vibration of the left and right vibrations is applied as a magnetic field. Since it is converted into an electric signal by the principle of modulation, the microphone does not react to the left vibration and does not generate noise. However, in an acoustic guitar, the vibrations of the strings are amplified by the entire guitar body and neck instrument, which makes it difficult to hear without mute. When sound is collected by a microphone for electrical amplification, for example, when a small sound collecting microphone is attached to the front plate, sound is collected up to this noise.

Therefore, if the performer is right-handed, the bottleneck bar should be attached to the middle finger, ring finger, or little finger of the left hand, and if the performance is to be performed with the middle finger of the left hand being played, Must be performed.

The movement of the index finger for mute requires a delicate touch and requires advanced techniques. The performer has to practice a lot in order to learn this technique. The same applies when the sound is muted with a finger other than the index finger.

The reason why the bottleneck bar of the prior art is not attached to the index finger is that the sound cannot be silenced. The bottleneck bar is not attached to the thumb. The finger to which the bottleneck bar is attached varies depending on the player's preference and the composition of the music, but most are attached to the ring finger or little finger. Also, the index finger is often used to mute the sound.

This means that two fingers must be used to hold and mute the bottleneck bar in the performance. In the performance using the bottleneck bar, the sound obtained by simultaneously pressing between the frets with the finger is used. It becomes a restriction when trying to use and perform. Actually, it is extremely difficult to exchange performances by pushing strings between frets. Obtaining these two different sounds simultaneously requires sophisticated performance techniques.

As an example, in order to add a bass fret to the sound of a bottle neck bar, the neck is turned around with the thumb and the 6th string is pressed to make a bass sound. However, on the contrary, it is impossible to add a sound higher than the sound at the position of the bottleneck bar if the bottleneck bar is attached to the little finger.

If you put it on the ring finger or middle finger, you may be able to push the string with one little finger or two with the ring finger and little finger, but in reality, the finger with the bottleneck bar must be straightened by its shape Because of this, the ring finger and little finger cannot move well. Training the movement of the ring finger and little finger to solve this problem is unrealistic because of the heavy burden on the finger muscles and tendons.

Also, since it is impossible to attach and detach the cylindrical bottleneck bar instantaneously during performance, it is difficult to switch to a performance method that does not rely on the bottleneck bar during performance. For example, playing with a bottleneck bar in the theme part of a musical piece, and not using a bottleneck bar in an interlude part, and performing by pressing a normal fret has a great performance restriction. The reason for this is that, among the four fingers normally used for pushing strings, one finger other than the index finger has a bottleneck bar, so that the number of fingers that can be pushed is three.

Actually, if the bottleneck bar is attached to the ring finger, the remaining fingers become the index finger, middle finger, and little finger, and the string finger is stretched so that the bottleneck bar does not touch the string, and the string is pushed with three fingers. Even with a simple and simple melody, it is extremely difficult to make a movement to play it.

In order to achieve this performance, some performers wear a bottleneck bar on the little finger. However, in this case, it is impossible to obtain the two different sounds at the same time. In any case, it requires very advanced performance skills and is difficult to learn. Because it puts a heavy burden on the finger muscles and tendons for practice, it is considered dangerous.

In the prior art, many cylindrical bottleneck bars are put on fingers and operated. For this reason, the part that determines the pitch in contact with the string is one point of the lowest part of the cylindrical outer periphery. This part is directly under the ring finger or pinky finger to be operated. In the prior art, this point cannot be visually recognized from the viewpoint of the performer. The reason is that one point at the lowest part is hidden on the outer periphery of the cylindrical shape.

This is one of the causes of difficulty in learning the bottleneck performance technique. In a normal finger-pressing technique, what is pressed with a finger to determine the pitch is the fingerboard portion between the fret and not directly above the fret. It is the fret that determines the pitch in the guitar, and the movement of the finger that presses the string is performed to strongly press the string against the fret. In other words, the pitch of the guitar is not determined by the fingers but by the frets.

However, in the bottleneck playing method of the prior art, this fret is replaced by one point at the bottom of the aforementioned cylindrical outer peripheral portion. And in order to obtain the correct pitch, one point of this lowest part has to be located right above the fret.

This requires the performer to learn a technique different from the feeling of playing a string with a normal finger. In other words, the position of the finger inserted into the cylindrical bottleneck bar of the prior art is also at the lowest part of the inner periphery of the cylindrical bottleneck bar, and the lowest part of this inner periphery with the thickness of the cylindrical bottleneck bar interposed therebetween. One point must be located directly above the fret.

The player must spend a great deal of time practicing to master this sense of position, which is different from playing with a normal finger-pressed string.

The bottleneck playing method is characterized by unstable pitches, vibrato, portamento, etc. However, as long as it is a musical performance, it is intentional and unstable only after obtaining an accurate pitch like a song. I think that a technique such as a simple pitch is effective. There is a need for a technique for obtaining an accurate pitch that is difficult to learn with conventional techniques.

In the prior art, glass, metal, plastic, bovine bone (the bone marrow is removed and the outer peripheral surface is polished), lead pipe and other cylindrical materials are used.

Of these, glass and metal are commonly used. In recordings of performers who were active in the United States before World War II, there were those who used cow bones, and even today, this material is still popular among lovers. However, at present, the above-described cylindrical cow bone is generally difficult to obtain, and it takes time to polish the surface.

Since a general bottleneck bar is cylindrical, if it is placed on a table or the like when not in use, it may roll and fall to the floor and crack. Or when carrying it, it breaks in the cage and the performer who tries to take it out may injure his finger with broken pieces. Not only is it dangerous, but hurting your fingers means that you can't play. In order to prevent this from happening, a cylindrical shape is placed upright, especially on a table. However, in reality, it is not stable and often falls and rolls with a slight vibration. Shapes that can lead to breakage are also a problem.

In the prior art, the pitch is determined by the tangent of any one of the cylindrical outer peripheral surfaces. Therefore, the cylindrical outer peripheral surface must be a curved surface with no unevenness over the entire surface so that sound can be produced regardless of where the string is struck. This means that engraving or printing with irregularities on the outer peripheral surface is impossible. In fact, the fashionability of the conventional technology is nothing. At best, you can wear some color on a glass bottleneck bar. However, guitar players are often illuminated during stage performances, and the performer's hand is often captured up when recording. Also, performers place emphasis on decoration and fashion to differentiate themselves from other performers and to assert themselves. The challenge is to enable colorful decorations and work with unique designs.

Therefore, the issues are as follows: 1 Put a bottleneck bar on your finger and automatically mute it.
2 It shall be possible to perform string pressing with a finger that has less burden on movement with a finger other than the finger with the bottleneck bar.
3. A shape that allows the performer to easily recognize one point on the outer periphery to obtain an accurate pitch.
4 Attaching multiple bars of different materials, such as glass, metal, and cow bones, to one bottleneck bar, and using different sounds.
5. Make it a shape that does not roll even when placed on a table or the like.
6. Make sure that the main body incorporates fashionable designs and ingenuity to enhance the stage effect, such as engraving, affixing, printing, etc., and light emission by charging small batteries and LEDs.

In order to solve the above-mentioned problems, the first invention is to perform noise reduction by providing a protrusion on the outer periphery of the bottleneck bar of the prior art and a space of several millimeters from the protrusion on the outer periphery of the string. Are provided with two points of protrusions that contact the string.

In the second invention, since these two points are always in contact with the string, the shape of the bottle neck bar is not a cylindrical shape but a triangular cylindrical shape, a gentle curve is provided on the outer peripheral side, and the distance between the two protrusions is provided in the cylindrical shape. Is larger than At the same time, with the triangular tube shape, the pitch is adjusted by positioning the protrusion that touches the string from the lowest part of the bottleneck bar to the corner of the triangle tube, the player side at the bottom of the bottleneck bar when viewed from the player. This makes it easy to visually recognize one point of tangent to be determined.

In the third aspect of the invention, in order to use different timbres properly, metal, glass, or other materials are separately bonded to each side of the outer periphery of the triangle for each purpose. At the same time, by providing two protrusions on each side of the triangular cylinder, it is shaped so that it does not roll even when placed horizontally and is stable even with some vibration.

According to a fourth aspect of the present invention, the projection is provided, so that it can be rolled and damaged even when placed sideways when not in use. In addition, the body uses aluminum, acrylic, and other materials to reduce the risk of injury due to breakage.

According to a fifth aspect of the present invention, by providing the protrusions, the main body can be engraved with other decorations, or can be provided with a light-emitting device that enhances the stage effect, thereby enabling a fashionable appearance.

According to the first invention, by using the index finger in the past, there are provided a projection at the portion in contact with the string and a projection in contact with the projection to provide a space several millimeters apart from the projection. The mute operation is unnecessary. As a result, the conventional technique cannot use only two fingers for performance, but the use of the present invention results in three.

If the invention is attached to the index finger, these three are the middle finger, ring finger, and little finger. Especially, the little finger can be moved easily without being affected by the extended index finger. The range of performance is widened by attaching a string and a second bottleneck bar.

Even when the invention product is used with the ring finger or little finger in the same manner as in the prior art, the same effect can be obtained because it is not necessary to use other fingers for silencing.

According to the second aspect of the present invention, when operating to a position for obtaining an accurate pitch in the prior art, one point of the lowest part that was hidden behind the bottleneck bar body and could not be seen is It is located just below the right of the finger with the invention. Thereby, the position of the tangent which could not be visually recognized conventionally can be easily visually recognized.

Furthermore, the position of the finger wearing the invention at this time is located slightly to the left of the fret that determines the correct pitch. This position is almost the same position as the performance sensation performed by normal string pressing with a finger. In the prior art, it is necessary to practice that a finger is operated on a fret different from a normal performance and the pitch is searched in a state where the finger cannot be visually recognized. If the invention is used, this practice is not necessary, and an accurate pitch can be obtained by an operation of movement close to a normal sense, and this can always be visually confirmed.

Further, according to the second invention, in order to stably contact the chord with the two points of projections attached to the outer periphery of the invention, the cylindrical body shape of the prior art is a triangular cylinder, A gentle curve was given to the side. By using this shape, it is possible to make a space between two points wider than attaching protrusions on the circumference, thereby making it possible to perform stable tangling.

According to the third aspect of the present invention, three different timbres can be obtained by using the triangular tube shape and attaching the protrusions of different materials and the muffling protrusions to the three sides having a gentle curve on the outer periphery. Can do. The performer uses a hollow bottleneck bar that is slightly larger than the size of the finger, so if necessary, the player can easily rotate the main body and switch to the side where the favorite material is pasted.

This means that only one player needs a bottleneck bar made of three materials of the prior art, which reduces the cost required for product purchase and makes it easier to store and carry.

According to the fourth aspect of the present invention, when not in use, by placing the two protruding portions of the tangent and the silencer down, it is possible to maintain a stable state without rolling.

Further, according to the fourth invention, since the main body part other than the two projecting parts of the tangent and the muffling need not be in contact with the string, even when the sound from the glass bottleneck bar of the prior art is obtained, the whole is made of glass. There is no need to be. This can reduce the risk of injury due to breakage.

Further, when a glass protrusion is attached to the main body, only the portion of the protrusion is in contact with the string, so that the main body does not need to be made of glass unlike the prior art. Light metals such as aluminum and materials that are resistant to impact such as acrylic materials can be used.

According to the fifth aspect of the invention, since the main body part other than the two projecting parts of the tangent and the mute need not be in contact with the string, various decorations that have been impossible in the past can be applied to the main body. It is possible to incorporate light-emitting devices with fashion work, printing, and stage effects. In the case of a cylindrical main body, various decorations can be applied to an area of about three quarters of the outer periphery of the main body.

One embodiment of the present invention is shown in FIG. The acrylic triangular tube of the main unit-1 is gently curved on the outer periphery, and a bar made of different materials made of glass, metal and cow bone and a bar made of a material for silencing are attached to the three sides. A projection that touches the string is formed.

The performer performs the performance by inserting the left index finger into the cavity and touching the two protrusions at right angles to the string.
"Effect of the embodiment"

In the prior art, when performing using a bottleneck bar, a great deal of practice was required to mute with the index finger. However, if the mute is performed automatically, such trouble is not necessary.

In addition, it is possible to exchange the sound of pushing the string between the frets with three fingers other than the index finger operating the product. The number of fingers that can be pushed more than that of the prior art is increased, and by using the invention product on the index finger, it is possible to add up to three sounds by pushing the middle finger, ring finger, and little finger.

Moreover, it becomes easy to obtain the melody with the other three fingers at the same time as obtaining the sound according to the invention. Alternatively, a performance technique that has been impossible until now can be achieved by attaching the inventive product to the index finger and simultaneously attaching the bottleneck bar of the prior art to another finger, for example, the little finger. This not only expands the range of performance styles, but may also lead to music that has never existed in composition and arrangement.

Even when the invention is attached to the index finger and the index finger is extended, the movement of the middle finger of the other fingers is affected by the index finger, but the movement of the middle and little fingers is relatively burdensome. Less is. In particular, the little finger can be moved easily.

This is probably because the ring finger and little finger, especially the little finger, are far away from the index finger due to the medical organization of the finger, and thus the movement of the index finger muscles and tendons is less affected by such movements. To do.

Also, when playing guitar, there is a position called Valley on the left hand position. This is a technique in which the index finger is extended for a long time and the strings 1 to 6 are simultaneously pressed with an arbitrary fret, but it is frequently used in playing a guitar.

Attach the bottleneck bar to the index finger as described above, and with the index finger extended long, the invention can be touched at the same time in parallel with the frets from the 1st string to the 6th string with the other finger. The position where the string is pressed is close to the position where the ballet is performed.

Therefore, the performer can easily move other fingers. As a result, even with the movement of one little finger, the movement of the little finger, which was impossible with the prior art, is realized.

Invented products can easily recognize a single point of tangency that determines the pitch, so that a stable and accurate pitch can be obtained. As a result, techniques such as intentionally unstable pitch, vibrato, and portamento, which are characteristic of the bottleneck performance, can be performed more easily and effectively.

The bottleneck bar in the prior art was made of glass, metal, bovine bone, etc., but it actually touches the string at one point on the outer circumference or in the direction perpendicular to the entire string. Only the 6 points are in contact.

Since the inventive product is connected to the bar for silencing at the same time, the two protrusions are attached to the main body. Therefore, unlike the bottleneck bar of the prior art, the whole need not be made of the same material.

Since the role required of the main body is only required to adhere the protruding portions so that the string can be stably connected, the main body can be made of a material that is easy to produce and process. There is no need to use a material that easily breaks and causes injury, such as a glass tube. It is presumed to be made of light metal or acrylic.

Of the materials used in the bar, cow bones are difficult to obtain in the prior art form, as described above. This is because the size of the cylindrical cow bone is not constant and the polishing of the surface takes time.

On the other hand, many cow bones are still processed and used as components of the guitar body. This is the part called the saddle in the front bridge, and the same material is used in the part called the nut for the part corresponding to the 0 fret before the head of the neck.

These are cut into an elongated shape with a thickness of 2 to 3 mm, a length of 70 to 100 mm, and a height of 10 mm. By applying this technology, a part to be pasted on the outer periphery of the triangular shape, which is the present invention, is made. I think it is easy. As a result, it is possible to provide a bottleneck bar made of cow bones, which has been difficult to obtain.
"Other embodiments"

In the embodiment of FIG. 2, it is assumed that the triangular tube portion of the main body is made of acrylic, but a light metal material such as aluminum may be used.

In the embodiment of FIG. 2, it is assumed that the main body is a triangular cylinder, and three different materials are attached to the projections that are in contact with the object, but if only one material is required, the conventional cylindrical shape is used. It is only necessary to attach two protrusions, one that connects the string and the other that mute. Also in this case, it can be stably placed by the two protrusions, there is no risk of rolling and breaking, and the main body need not be made of glass.

When the main body is crafted, one protrusion can be connected to the cylindrical main body, and the outer peripheral surface can be crafted except for attaching this protrusion and a muffing protrusion. The area ratio is about three-quarters of the entire outer peripheral surface.

When the light emitting device is incorporated in the main body, it is preferable that a button battery or a switch is installed in the cavity opening on the opposite side of the main body cavity, the fingertip side, etc., and the LED is emitted by wiring on the outer periphery.

The embodiment described in this document assumes a right-handed player and is attached to the left index finger. Some guitar players have a small but dominant hand and must be worn on the right index finger for implementation. In that case, the up-down direction of the main body is reversed and the index finger is inserted through the opposite mouth.

The embodiment described and illustrated in this document assumes that the type of guitar to be played is a steel string, but some performers may use a nylon string guitar. is there. In that case, the effect is the same as steel strings.

It is a perspective view showing one embodiment of this invention. It is a figure which shows a prior art bottleneck bar. 1 Body 2 Tangling part
