Description

  The present invention relates to a stringed instrument composed of a melody string and a chord string, and more particularly to a stringed instrument suitable for infants, the elderly, and the physically handicapped.

  Conventional stringed instruments have been developed in various ways, as represented by guitars, violins, shamisen, kotos, etc., and many performers and enthusiasts use them to perform.

  These stringed instruments generate various sounds by playing a plurality of strings, perform the performance by changing the tone by pressing the position of each string with a finger, and require a certain performance technique.

  In addition, when playing music, it is necessary to play a melody and accompaniment to play chords.

  When singing a song, it is also common to play an accompaniment with a guitar or the like.

  When playing chords, three chords are common and require a certain skill and skill, such as using a plurality of strings and pressing the position of each string with a finger.

  For this reason, beginners required considerable skill and were considered difficult to use for infants and the elderly.

  For this reason, many electronic musical instruments have been developed as musical instruments that can perform chords and the like more easily.

  In this electronic musical instrument, various chords can be easily generated with a single button operation.

  As a chord generating string instrument, Japanese Patent Laid-Open No. 2003-345343 discloses a guitar-type chord generating string instrument in which chords are generated with four strings and a fret is pressed with one finger to generate various chords. Is disclosed.

Also, in Japanese Patent Application Laid-Open No. 11-352956, three sets of five strings, a total of 15 strings are stretched, and a chord-like chord is tuned so that a chord is generated in units of five on the support. An apparatus is disclosed.

  However, electronic chords that generate various chords at the press of a button are not chords themselves, so the exact same chords will be produced by anyone playing them. Even if sound is produced, it is an electronic sound, and it is not interesting as a performance of stringed music.

  In Japanese Patent Application Laid-Open No. 2003-345343, since a chord is generated by playing four strings, it can be played with the feeling of actually playing a stringed instrument, but there is a need for complicated fingering to accompany a song. Not, but you have to hold the frets together with 4 fingers with one finger.

  In the case of an infant, an elderly person, or a physically handicapped person, it is not easy to press the four strings together to hold the fret.

  In Japanese Patent Application Laid-Open No. 11-35295, a chord must be tuned by a support in units of five strings.

  In order to make the position of the support easy to understand, it is necessary to perform an operation for aligning the support for each string before the performance even if the support is marked on the sounding body. .

  An object of the present invention has been made in view of the above problems, and is to provide a stringed instrument that can be easily operated and played even by an infant, an elderly person, a disabled person, and the like.

  In order to solve the above-mentioned problem, according to claim 1 of the present invention, in a three-line type stringed instrument in which a string is stretched between the buttocks and the torso and a sound is generated by playing the string, the arrangement of the strings is 1 string. A stringed instrument comprising a melody string and a plurality of chord strings with a set of three strings.

  According to a second aspect of the present invention, there is provided a stringed musical instrument characterized in that four sets of chord strings having the three strings as one set are provided.

  According to claim 3 of the present invention, the four chord strings are tuned to a four chord composed of a combination of a major three chord chord that is the basis of chord progression and a minor one chord. The stringed instrument according to claim 2, comprising a chord string.

  According to a fourth aspect of the present invention, in the stringed instrument, a mark for identifying each chord string is displayed on the surface of the body portion corresponding to each chord string.

  According to a fifth aspect of the present invention, there is provided a stringed instrument in which a character symbol corresponding to the melody string and indicating the position of the scale is displayed on the surface of the buttock.

  According to a sixth aspect of the present invention, the stringed instrument is characterized in that the melody string is made of nylon and the chord string is made of steel.

  The present invention has the following effects.

  1) Since chord strings can play chords in an open string state, they can be accompanied with one hand.

  2) You can play the natural sounds of stringed instruments by playing either melody strings or chord strings as they are, and even young children, the elderly, and the handicapped can enjoy playing with strings.

  3) Since both melody strings and chord strings are provided, performances including accompaniment can be performed with only one hand.

  4) When accompaniing a song, accompaniment can be achieved without learning fingering of the chord of the music.

  5) Since typical 4 chords can be produced, it is possible to perform accompaniment of music sufficiently with only the 4 chords.

  6) Since a mark for identifying four chord strings is displayed on the body, it is easy to understand which chord string to play.

  7) Since the character symbol indicating the scale is displayed on the buttocks, it is easy to play the melody.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a plan view showing an embodiment of a stringed musical instrument according to the present invention, and FIG. 2 is a vertical sectional view thereof.

  The stringed instrument is provided with a winding unit 2 for adjusting the tension of the string, and includes a collar unit 3 that is a position where the string 1 is pressed with a finger to change the pitch, and a body unit 4 that resonates the vibration of the string 1. 4 strings of chord strings (1b1 to 1b4) that are a set of 3 strings are stretched.

  The melody string 1a is a nylon string, and the chord string 1b is a steel string.

  The head 3a of the buttocks 3 is depicted with a unique character face inspired by Okinawan seasa.

  Further, on the surface of the heel part 3 where the melody string 1a is located, the scale symbol 5 of “do” “le” “mi” “fa” “so” “la” “shi” “do” is placed at the position corresponding to the scale. Is written.

  Further, the number 6 of “1”, “2”, “3”, and “4” is displayed on the body 4 at positions according to the four sets of chord strings 1b.

  As shown in FIG. 2 (AA longitudinal cross section in FIG. 1), the inside of the body portion 4 is hollow and serves as an acoustic resonator.

  Moreover, as shown in FIG. 2 and FIG. 3 which is a cross-sectional view of the head portion of the collar portion 3 (BB cross section in FIG. 1), the head portion of the collar portion 3 is hollow and wound inside. A take section 2 is provided.

  The four chord strings 1b1 to 1b4 are in an open state, the three chord strings are G major three chords (G, C, D), and the remaining one chord string is the Em in the diatonic chord. The chord string was used.

  That is, from the right side, the first string 1a is a melody string tuned to G major, the second string 1b4 is a chord string tuned to a G chord that is a tonic chord of the G major key, and the third string 1b3 is , A chord string tuned to the C chord that is the dominant chord of the three chords of the G major key, the fourth string 1b2 is a chord chord tuned to the D chord that is the sub-dominant chord of the three chords of the G major key, the fifth chord The string 1b1 is a chord string tuned to the Em chord in the G major key diatonic chord.
