DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device that can easily generate a chord, and more particularly to musical instruments that can easily generate a chord simply by vibrating a string.

[0002]

2. Description of the Related Art Since ancient times, tools and devices for generating sound have been used as means for transmitting human intentions and emotions, and various musical instruments such as wind instruments, string instruments, percussion instruments and the like have been used to perform music by applying the tools. Has been developed and used. Among them, tools, devices and musical instruments having a string are basically provided with a string or string in the outside of a box-shaped device having a function as a sounding body, and the strings, fingers, claws and bees are attached. A sound can be generated by vibrating with a suitable means such as, for example, and a single sound can be generated in principle like a wind instrument or a percussion instrument.

However, unlike other musical instruments, a stringed instrument has a special part called a string, and a technique of vibrating the string can generate various complex tones, scales, and sounds, including chords. It is possible. However, for this purpose, when a conventional stringed instrument is used, usually, a string stretched to a certain length using one finger or hand, that is, an open string, is held at a predetermined position so that a desired sound is generated, while the other string is held. It is necessary to perform an operation of flicking and vibrating the string with the finger or hand of the user. That is, in order to generate a more complex and tasteful sound, for example, a chord obtained by vibrating a plurality of strings at the same time or almost at the same time, a predetermined single tone constituting the chord is generated in the above operation. It is necessary to use a plurality of strings that are not adjacent to each other while setting the position of the length of the open string, and requires extremely high skill and skill in finger and hand movements.

[0004] For this reason, infants learn to operate musical instruments, and physically handicapped people have learned more advanced operating methods using healthy parts of the body. In addition, music therapy for elderly people with reduced physical and / or mental function has recently attracted attention, but even in this case, listening to music to adjust emotions and reduce mental stress. In addition to doing this, attempts have been made to maintain and improve both physical and mental functions by playing musical instruments by themselves. At this time, the player has a strong desire to play qualitatively advanced music, that is, a more complex and tasteful tone and sound.

However, the musical instruments used in these cases are almost the same type and the same type as those used by healthy persons, and can be easily operated by infants, physically handicapped persons and the elderly to produce high quality sounds. At present, there are no musical instruments suitable for easy generation, especially string instruments. For this reason, the operator or the player is forced to spend an excessive amount of effort compared to the case of a healthy person,
As a result, even if it is recognized that playing music by yourself is useful for maintaining, managing and improving mental and physical health, it is effective only in very few cases.
Accordingly, there is a need for a stringed musical instrument that can easily and easily produce high-quality timbres such as chords.

[0006]

SUMMARY OF THE INVENTION In view of the above situation, the present invention provides a chord generator which can be operated simply, easily and easily by healthy persons as well as infants, physically handicapped persons and elderly persons. It was aimed at.

[0007]

The chord generating device according to the above-mentioned subject comprises a plurality of strings tuned so as to generate a sound of a scale constituting a chord by vibrating the strings, and the strings are arranged adjacent to each other to form a sound body. This can be achieved by a chord generator. This chord generator uses a plurality of adjacent strings as a string unit when a set composed of a plurality of adjacent strings tuned so as to generate a sound of a scale that constitutes a chord by vibrating is used as a sound source. It is desirable to be stretched on the body. The chord generating device of the present invention is preferably a Japanese musical instrument having a string, and more preferably the Japanese musical instrument is a koto.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A chord generating apparatus according to the present invention basically comprises a plurality of strings tuned so as to generate a sound of a musical scale which constitutes a chord by vibrating, so that a plurality of strings are arranged next to each other in a resonating body. It is an indispensable constituent requirement to install it. The basic structure of the chord generator of the present invention is as shown in FIG.
A plurality of strings of an arbitrary length and thickness, for example, a first string 2 are provided on the upper surface of a sounding body 1 in the form of a box-shaped container made of a suitable material such as wood, paper, metal, or synthetic resin. , A second string 3 and a third string 4 are formed. First string 2,
The second string 3 and the third string 4 are open strings having both ends fixed to the sounding body 1 and stretched so as to be adjacent to each other so that they do not contact each other. It is supported by a removable support 7.

Each string is vibrated by an appropriate means such as a finger, a claw, a bee or the like, so that a single note of a scale constituting a chord, for example, the first string 2 is C, the second string 3 is M, The third string 4 can be tuned by adjusting the position of the support 7 in advance so as to generate each single sound of the singer. By adjusting the thickness of each string, it is possible to tune so as to generate a single tone of a scale that constitutes a chord. Also, the thickness of each string and the position of the support 7 can be adjusted. Can be used together.

In order to operate the chord generating device of the present invention, first, as a preparatory operation, a tone generated by playing each string is tuned. That is, as described above, the support that supports each string is appropriately moved and tuned so that each note of the scale that constitutes the chord is formed. For example, the first string 2 in FIG.
With regard to the above, the position of the support 7 is set such that the sound of the scale of C is generated by playing the string between the right end fixing portion and the support 7. The second string 3 and the third string 4 are similarly set so as to generate a sound of the scale of Mi and So. Since the three strings tuned in this manner are stretched adjacent to each other so as not to contact each other, a chord is generated by simply playing these strings simultaneously or almost simultaneously with one finger, a claw, a pick or a bee. be able to.

On the other hand, in order to generate a chord using a conventional stringed musical instrument, it is necessary to hold down a string tuned so as to generate a sound of a predetermined scale with one finger, and to generate a single note of a scale that constitutes a chord. It is necessary to play the string with the other finger, claw or bee while appropriately setting so as to produce a chord, and simultaneously or simultaneously set another string set so as to generate another note of the scale constituting the chord. It is necessary to play almost simultaneously. Therefore, not only healthy people but also infants, physically handicapped people,
In order for an elderly person or the like to generate a chord using a conventional stringed instrument, it is essential to use both hands and a complicated operation is required. If the movement function of one hand is inconvenient, it is substantially impossible to generate a chord using a conventional stringed instrument. However, with the chord generating device of the present invention, it is possible to easily generate a chord simply by playing a plurality of strings with one hand.

Although the chord generating device of the present invention has the above-mentioned structure, the type and number of chords that can be generated are limited when only three strings are stretched as illustrated in FIG. . In order to generate more qualitative timbres, that is, more types and numbers of chords, in the above-mentioned chord generator, a plurality of tunes are generated by vibrating to generate a tone of a scale that constitutes a chord. When a set composed of adjacent strings of a book is a string unit, it is preferable that a plurality of string units be stretched over the sound body.
This will be described with reference to the three strings shown in FIG. 1. In this case, three aggregates (string units) of the strings are arranged adjacent to the upper surface of the sounding body so as to form a plurality of aggregates. This is a mode in which strings are arranged and stretched over a sound body.

At this time, the string unit, that is, the number of string aggregates is arbitrary and is not particularly limited, and may be determined in consideration of the operation skill of the operator and desired sound quality.
If the number is too small, the types and number of chords are limited, and only a simple generated sound is obtained. Conversely, if the number is too large, the operation tends to be complicated. For this reason, the practical number of string units is, for example, 1 to 15 when the string unit is composed of two strings capable of generating a chord, that is, the total number of strings is preferably 4 to 30, and furthermore, More preferably, the string unit is 3 to 8. When the string unit is composed of three strings that can generate a chord, 1 to 10, that is, the total number of strings is 3 to 3
The number of strings is preferably 0, and more preferably the number of strings is 2 to 6. Further, when the string unit is composed of five strings that can generate a chord, it is preferable that the string unit is 1 to 6, that is, the total number of strings is 5 to 30, and further the string unit is 2 to 4. Are more preferred. As described above, in the chord generating device of the present invention, the total number of strings and the number of string units can be set in any combination. The spacing between adjacent strings may be set to such a degree that they do not touch each other as in the case of conventional stringed instruments, but the spacing between adjacent strings is slightly greater than the spacing between strings in consideration of operational convenience. It is desirable to set widely. Of course, it is possible to set the same interval between each string and each string.

The chord generating apparatus of the present invention employs various conventional stringed instruments such as guitar, violin, mandolin, ukulele, cello, contrabass, shamisen, koto, Taisho koto, etc. It can be manufactured and used as a chord generating string instrument. In particular, when playing various songs, it is desirable to use a Japanese musical instrument having a string such as a shamisen or a koto, which has no concept of generating a chord. Further, as shown in FIG. The form is more preferable. In addition, it is preferable that the chord generating device of the present invention be in the form of a Japanese musical instrument such as a koto, since elderly people have a high interest in Japanese musical instruments, and particularly have a strong degree of liking for the tone of the koto. .

FIGS. 2 to 4 show an example of a chord generator of the present invention employing a koto form. As shown in FIG. 2 and FIG.
Two open strings made of Tetron are stretched, and as shown in FIG. 2, the open strings are grouped into five by a support unit 8 and fixed to the left end of the sound body 1 as strings, and 15 open strings are provided. The open string is the support portion 9 and the pore 1 on the right side of the sound body 1 respectively.
0, it is fixed to each string tensioning screw 11. Each open string is attached to the string tensioning screw 11 by the handle 1 shown in FIG.
2 and adjusting the tension of each string by rotating the handle so as to tune all open strings to produce the same pitch. Next, a support 7 shown in FIG. 6 is erected below each open string, and each string generates a single tone of a predetermined scale, that is, a scale constituting a chord, and in the case of FIGS. Is played at the same or almost the same time as the five strings that make the chord so that a chord is generated.

Although the chord of each string composed of five strings may be the same, if the tone of each string and each string is tuned so as to generate a different chord, the chord is wider, deeper, and more varied. This is preferable because a chord having a certain tone and resonance can be generated. Also, for example, in the C chord, a chord is composed of three single tones from the bottom of the scale, do, mi, and so, and the sound of the do is the root note, but in the case of five strings, the lowest note is the root note. It is tuned so that it becomes the sound of C one octave below C and the highest sound is the sound of C one octave above C of the root note. At this time, in consideration of operational convenience, the sound of the string closest to the operator (the lowest string in each string in FIG. 2) becomes the lowest sound, and the scale becomes higher in one direction. It is preferable to tune in such a way. This tuning method can be appropriately changed according to the timbre, sound, musical sense, etc. of the generated chord.

This chord generating device generates a chord simply by simultaneously or almost simultaneously playing a plurality of strings constituting a string unit with one finger, a fingernail, a pick or a bee (neither is shown). Can be generated. The chord generating device of the present invention is suitably used when a chord accompaniment is added to various songs and melodies, and can also be effectively used when playing the tune itself according to a tune arranged in a chord. Naturally, not only chords but also single tones can be generated, and the same usage as a conventional stringed instrument can be performed.

[0018]

According to the present invention, not only a healthy person who is not used to operating a stringed musical instrument but also an infant, a physically handicapped person and an elderly person can easily perform the operation with only one hand or finger.
A chord generating device capable of easily and easily generating a chord can be provided. This chord generator can generate not only one kind of chord, but also a high-quality sound having a wide range of timbres, reverberations, etc. combined with a plurality of chords.
Of course, it is also possible to generate a note of a scale constituting a chord as a single note. Such a chord generating device of the present invention is suitably used when a chord accompanies various songs or melodies, and can also be effectively used when playing the tune itself according to a tune arranged in a chord. By operating the chord generator of the present invention, the elderly or physically handicapped, whose physical and / or mental function has been reduced, can be expected to prevent a decrease in motor function and to enhance its alternative function, and furthermore, to simply play music. In addition to the interest in listening to and enjoying listening to music, he also plays musical instruments to increase interest in music, regulates his own emotions and emotions, and promotes a shift from passive thinking and behavior to active thinking and activity. It can also be expected to improve and activate mental functions such as doing.
