Description

  The present invention relates to a shamisen pick.

  A shamisen (also called “Sansen” in the Okinawa region), an Okinawan folk instrument, is generally provided with a snake skin spread on the front or back opening of the trunk frame. For performance of this type of shamisen, an armor (also called a bee) that is detachably attached to the index finger is usually used. Prosthetics are made of animal horns or, recently, synthetic resins and are three-dimensionally formed into claws. That is, the prosthetic arm is generally curved, and its tip is sharpened. The player of the shamisen performs by hooking the tip of Yoshio to the string of the shamisen (see, for example, Non-Patent Document 1). Also, instead of this artificial armor, a triangular plate pick of a stringed instrument such as a guitar has recently been used because of its availability and ease of operation. Various types of picks are known depending on the application (for example, Patent Document 1).

  However, the conventional prosthetic arm has a relatively large shape and poor operability. Moreover, when a performance music is fast (for example, BPM is 130 or more), the tip of a prosthetic arm may be sharp, and the catch to a string may become strong. In addition, in order to prevent the unnecessary strong catch, the tip of the prosthetic arm is processed into a round shape, or the manner of gripping the prosthetic arm during performance is changed, which makes the handling complicated. It could not handle the speed of a wide range of performance songs, from slow to fast, and lacked versatility. This complexity has been a hurdle for beginners to learn the shamisen. Similarly, the triangular plate pick has a pointed tip, and there is room for improvement.

  The present invention has been made in view of the above-described circumstances, and the purpose of the present invention is to appropriately change the corner portion to be used according to the speed of the performance music with a single pick and to use the music with high speed. Even when playing a song with slow speed, sharpening the tip to improve the quality of the shamisen performance and improving versatility makes it easier to learn the shamisen performance. The object is to provide a shamisen pick that can be done.

The object of the present invention is achieved by the following configuration.
(1) It is formed in a pentagonal plate shape, has five corners,
The interior angles of the first corner and the second corner are respectively set to be less than 90 ° at different angles, and are used to improve the tone quality during performance,
The interior angles of the third corner and the fourth corner are set to 90 ° or more and less than 180 ° at different angles, respectively, and are used so that the shamisen is not caught on the strings when played,
A shamisen pick characterized in that the inner angle of the fifth corner is set to 180 ° or more.
(2) The pick for a shamisen according to (1), wherein the first and second corners are arranged adjacent to each other with the fifth corner therebetween in the circumferential direction.
(3) The shamisen pick according to claim 1 or 2, wherein an insertion hole for inserting a predetermined string body is formed in a central portion of the pick body.

According to the configuration of (1) above, it is possible to prevent unnecessary catching of strings even in high-speed songs by appropriately changing the corners to be used according to the speed of the performance music with a single pick. However, when playing a song with a slow speed, it is possible to improve the quality of the performance of the shamisen and improve the versatility by making the tip sharp, and to make it easier to learn the performance of the shamisen.
According to the configuration of (2) above, the operation portion at the center of the pick can be set relatively large, and the operation at the center of the pick can be performed while placing a finger on the side surface of the pick body facing the corner portion used in the performance. The part can be picked with another finger. As a result, the pick can be stably gripped without slipping, and the performance can be made easier with less fatigue.
According to the configuration of (3) above, since the string body is inserted and fixed in the insertion hole, when the string body is attached to the body of the shamisen at the other end, the pick is separated from the main body of the shamisen. It is easily held and can prevent the pick from being lost or forgotten to bring.

  According to the shamisen pick of the present invention, it is formed in a pentagonal plate shape, has five corners, and the inner angles of the first corner and the second corner are different from each other and less than 90 °. The inner angles of the third corner and the fourth corner are set to 90 ° or more and less than 180 ° at different angles, respectively, and the inner angle of the fifth corner is set to 180 ° or more. The For this reason, by changing the corners used according to the speed of the performance song with a single pick and using them properly, even if the song is fast, unnecessary string catching is prevented, and slow songs Playing with a sharp tip improves the quality of the shamisen performance and improves versatility, making it easier to learn the shamisen performance. In addition, since the operation part in the center of the pick can be set relatively large, you can hold the operation part in the center of the pick with another finger while placing your finger on the side part of the pick body that faces the corner used for playing. Can do. Accordingly, the pick can be stably gripped without slipping, and the feeling of fatigue can be reduced and the performance can be facilitated.

  The present invention has been briefly described above. Further, details of the present invention will be further clarified by reading a form for carrying out the device described below (hereinafter referred to as “embodiment”) with reference to the attached drawings.

This Okinawan shamisen 10 includes a trunk 11, a collar 14, a string 15 stretched over the trunk 11 and the collar 14, a shamisen pick (hereinafter also referred to simply as a pick) 20, It is comprised.

The trunk portion 11 is formed in a substantially rectangular ring shape, and includes a wooden trunk frame 12 having a cavity therein, and a pair of vibrating membrane bodies 13 and 13 that block both openings (not shown) of the cavity of the trunk frame 12. Composed. That is, the cavity of the trunk frame 12 is closed and airtight by the pair of front and back vibrating membrane bodies 13 and 13, and the trunk portion 11 functions as a resonance space for the shamisen 10. The vibrating membrane 13 is formed from a sheet member made of, for example, synthetic resin or cloth.
In the present embodiment, the pair of vibrating membrane bodies 13 and 13 are provided in both openings of the cavity of the trunk frame 12, but the present invention is not limited to this. Only one of the two openings (for example, the front side of the body portion 11) may be used. Further, the vibration film body 13 of the present embodiment is not provided on the back surface, and a snake skin may be attached instead. Moreover, in this embodiment, the horizontal dimension of the trunk frame 12 is set to 190 mm, the vertical dimension is 200 mm, and the height dimension is set to 80 mm. Moreover, the thickness dimension is set to 20 mm.

  The heel part 14 is formed to extend in a rod shape from wood such as redwood, rosewood, flower forest or ebony, in addition to the genus Oysteraceae. The base portion of the collar portion 14 is fitted into the body portion 11, and is fixedly supported by the body portion 11 with a part of the base end portion exposed to the outside from the body portion 11. And the bobbin part (not shown) is provided in the front-end | tip part of the collar part 14. As shown in FIG. In the bobbin, three bobbins (not shown) are alternately arranged on the left and right. A string 15 is wound around the bobbin. The string 15 is made of, for example, synthetic resin fibers such as nylon (registered trademark) and Teflon (registered trademark), silk, and the like, and is stretched and fixed across the trunk portion 11 and the collar portion 14.

  The central portion of the main body of the pick 20 is an operation portion 20A (see FIG. 2), and a pair of insertion holes 26, 26 are formed through the operation portion 20A in the thickness direction. The string S is inserted and tied into the pair of insertion holes 26 and 26. Moreover, this string S is attached to the trunk | drum 11 of the shamisen 10 at the other end, and is fixed. With this string S, the pick 20 can be easily and easily separated from the shamisen 10 body, and the pick 20 can be prevented from being lost or forgotten.

<Pick configuration>
Next, the configuration of the pick 20 of the present embodiment will be described with reference to FIGS. FIG. 2 is a plan view for explaining the shamisen pick 20 shown in FIG. FIG. 3 is a perspective view for explaining a state in which the shamisen pick 20 shown in FIG. 1 is picked with a finger.

  As shown in FIG. 2, the pick 20 of the present embodiment is formed in a pentagonal thin flat plate as a whole, and an operation unit 20 </ b> A disposed at the center of the main body of the pick 20, and outside the operation unit 20 </ b> A. And five corners (first to fifth corners) 21, 22, 23, 24, 25 arranged. The player of the shamisen 10 performs by picking the operation part 20A of the pick 20 with his / her finger in the thickness direction.

  The thickness of the pick 20 is set to about 0.5 mm to 1.2 mm. The pick 20 is provided from a sheet member made of synthetic resin such as polyethylene terephthalate or nylon (registered trademark). By stamping the sheet member, the pick 20 can be manufactured in large quantities at a low cost. In addition, the material of the pick 20 can be appropriately selected from resin materials such as celluloid, delrin, gator grip, ultem, and polyacetal. One of these resin materials may be selected and used alone, or two or more may be selected and combined (laminated). However, in the present embodiment, polyethylene terephthalate is more preferable.

In the present embodiment, the inner angles A1 and A2 of the first corner portion 21 and the second corner portion 22 are set to different angles and less than 90 °. Preferably, the inner angle A1 of the first corner 21 is set in the range of 50 ° to 60 °, and the inner angle A2 of the second corner 22 is set in the range of 70 ° to 75 °. The inner angles A3 and A4 of the third corner portion 23 and the fourth corner portion 24 are set to different angles and not less than 90 ° and less than 180 °. Preferably, the inner angle A3 of the third corner 23 is set to 90 ° (right angle), and the inner angle A4 of the fourth corner 24 is set to a range of 105 ° to 110 °. The inner angle A5 of the fifth corner 25 is set to 180 ° or more, and preferably in the range of 210 ° to 220 °. Moreover, in this embodiment, each corner | angular part 21, 22, 23, 24, 25 is formed in the pointed shape.
In addition, you may form the front-end | tip of each corner | angular part 21, 22, 23, 24, 25 with roundness. Further, only the first and second corner portions 21 and 22 may be rounded.

  The first and second corners 21 and 22 are arranged adjacent to each other with the fifth corner 25 interposed therebetween in the circumferential direction of the pick 20 body. In other words, in the circumferential direction of the pick 20 main body (counterclockwise in FIG. 2), the first corner 21 is used as a base point, then the fifth corner 25, then the second corner 22, and then The corners 21, 22, 23, 24, 25 are arranged in the order of the third corner 23 and finally the fourth corner 24.

  And about the magnitude | size of the pick 20, the dimension D1 between the 1st and 2nd corner | angular parts 21 and 22 in the left-right direction of FIG. 2 is set to the range of about 35 mm to 55 mm. In addition, the dimension D2 between the second and third corners 22 and 23 in the vertical direction of FIG. 2 is set to a range of about 30 mm to 50 mm.

  As shown in FIG. 3, when playing the shamisen 10 using the pick 20 configured as described above, the performer places the finger 20 (for example, an index finger) on the side surface of the operation portion 20 </ b> A of the pick 20 facing the portion used in the performance. ), The operation unit 20A at the center of the pick 20 is picked and played with other fingers (thumb and middle finger) in the thickness direction. At this time, the corners 21, 22, 23, and 24 used in the performance are appropriately selected and used in accordance with the speed of the performance music. However, the fifth corner 25 is not used for performance.

  More specifically, as shown in Table 1, using BPM (Beats Per Minute) as an index indicating the speed of a performance song, the performance song speed is about 30 BPM to 70 BPM. The corner 21 is selected and used for performance. As a representative performance song of Okinawan folk songs in this range, a so-called “sympathy” with a slow tempo is exemplified, and the first corner portion 21 is optimal at this “sympathy”. When the performance music is in the range of about 70 BPM to 100 BPM, the second corner 22 is selected and used for performance. A typical performance song in this range is a so-called “combination song” in which both men and women have a general playing tempo. The second corner 22 is most suitable for this “combination”.

When the performance music is about 100 BPM to 130 BPM, the third corner 23 is selected and used for performance. Typical Okinawan folk songs in these ranges are songs that are played at an early tempo and become a dance of Kachashie, and the third corner 23 is optimal for this type of song. Furthermore, when the performance music is 130 BPM or more, the fourth corner 24 is selected and used for performance. Uptempo Katachashi is exemplified as a representative performance song of Okinawan folk songs in this range, and the fourth corner portion 24 is optimal at this Katcharsee.
Kachashie is the last song to be danced at a celebratory table, such as a wedding, and is gradually played sooner.

  Thus, by using the corners 21, 22, 23, 24 used in the pick 20 in accordance with the speed of the performance music, it is possible to deal with performance music of various speeds with one pick 20. For example, the shamisen plays a clear sound, and Kachashie allows the shamisen 10 to be played without being caught by the strings 15. Also, guitar picks usually get tired without a sense of stability because they are gripped by the index finger and thumb. On the other hand, the pick 20 according to the present embodiment grips at three points of the index finger, the middle finger, and the thumb, so that there is a sense of stability and a feeling of fatigue is small.

<Advantages of this embodiment>
As described above, according to the shamisen pick 20 of the present embodiment, it is formed in a pentagonal plate shape, has five corners 21, 22, 23, 24, 25, and the first corner 21 The inner angles A1 and A2 of the second corner portion 22 are set to be different from each other and less than 90 °, and the inner angles A3 and A4 of the third corner portion 23 and the fourth corner portion 24 are different from each other. Each angle is set to 90 ° or more and less than 180 °, and the inner angle A5 of the fifth corner 25 is set to 180 ° or more. For this reason, the corners 21, 22, 23, and 24 that are used in accordance with the speed of the musical piece to be played with a single pick 20 are appropriately changed and used properly, so that the string 15 is unnecessarily caught even in a high-speed song. The performance of the shamisen 10 can be improved and the versatility can be improved by making the tip sharp when playing a song with a slow speed.

  Further, according to the shamisen pick 20 of the present embodiment, the first and second corner portions 21 and 22 are arranged adjacent to each other with the fifth corner portion 25 interposed therebetween in the circumferential direction. For this reason, the operation part 20A in the center of the pick 20 can be set to be relatively large, and the pick 20 is placed while placing a finger on the side face of the pick 20 body facing the corner parts 21, 22, 23, 24 used in the performance. The operation part 20A at the center of 20 can be picked with another finger. Thereby, the pick 20 can be stably gripped without slipping, and it can be made easy to play with less fatigue.

  Further, according to the shamisen pick 20 of the present embodiment, the insertion hole 26 for inserting the predetermined string S is formed in the center portion of the pick 20 main body. For this reason, since the string body S is inserted and tied into the insertion hole 26 and fixed, when the string body S is attached to the body 11 of the shamisen 10 at the other end, the pick 20 is separated from the main body of the shamisen 10. It can be held easily and the pick 20 can be prevented from being lost or forgotten.

  In addition, this invention is not limited to what was illustrated to the said embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
