Description

 The invention relates to the production of musical instruments, in particular, to the production of plucked string musical instruments, for example, guitars.

 Known stringed musical instrument containing a fingerboard connected to the body with the upper nut, a head with tuning mechanisms associated with one end of the strings, the lower nut, and a stand for securing the other ends of the strings, while the strings are located at different distances relative to the upper deck with the formation of the upper and the lower ranks, and the decks carry acoustic elements (see SU, copyright certificate, 1547025, CL G 10 D 1/00, 1988).

 A disadvantage of the known musical instrument is the low sound quality and limited gaming capabilities.

 The technical result of this proposal is to improve the sound quality and expand the variety of works performed.

 This is achieved by the fact that the working surface of the lower nut is 10 13 mm, the depth of each stage is 2 3 mm, the width of the protrusion of each stage is 3 4 mm, the width of the depression is 8 9 mm, the protrusion of each stage is made with the possibility of placing one string, the depression of each stage made with the possibility of placing several strings, the distance between the strings located on the adjacent protrusions is 12 mm, and the distance between adjacent strings located on the protrusion and the depression is 2 3 mm, while made of various materials.

 The strings of one row are made of metal, and the other synthetic.

 Grooves for strings are made on the lower nut.

 The stand has 18 holes for securing strings.

 Tuning mechanisms on the head are located in mutually perpendicular planes.

 In FIG. 1 shows a head with tuning mechanisms and a neck, in FIG. 2 is a rear view of the nut, in FIG. 3 rear view of the stand.

 A stringed musical instrument contains a neck 1 (not shown) of the neck 1 with the upper nut 2, the head 3 with tuning mechanisms 4, connected with one end of the strings 5, 6, the lower nut 7, and a stand 8 for securing the other ends of the strings 5, 6 .

 The strings 5, 6 are located at different distances relative to the upper deck (not shown) with the formation of the upper 5 and lower 6 rows, and the decks (not shown) carry acoustic elements (not shown).

 The working surface of the lower nut 7 is made stepwise 9, 10, the Height h of the lower nut 7 is 10 13 mm, the depth "a" of each stage is 2 3 mm, the width "b" of the protrusion of each stage is 3 4 mm, the width of the depression is 8 9 mm, the protrusion 9 of each stage is configured to accommodate one string, the cavity 10 of each stage is configured to accommodate several strings.

 The distance "l" between the strings located on the adjacent protrusions 9 is 12 mm, and the distance "m" between the adjacent strings located on the protrusion 9 and the depression 10 2 3 mm.

 Strings 5, 6 are made of various materials.

 The strings 5 of one row are made of metal, and the other 6 are synthetic, for example, of nylon.

 On the lower nut 7, grooves (not shown) are made to accommodate the strings.

 In the stand 8, 18 holes 11 are made for securing the strings 5, 6.

 The tuning mechanisms 4 on the head 3 are located in mutually perpendicular planes.

 They use a stringed musical instrument as follows.

 Before the game, a musical instrument is tuned. The basic structure of the guitar (GRAN, GRAN) is unison-octave. To do this, change the tension of the strings, starting from the bottom 6 of the string. One of the properties of acoustics of a stringed musical instrument, a guitar, is the resonance of metal strings into which they enter from the sound of synthetic nylon strings. This acoustic effect lengthens the duration of the sound of the fundamental tone (sound) from the nylon string, making the instrument sound more complete, surround. At the same time, the metal strings themselves are not affected during sound extraction.

 Another property of acoustics is the extraction of sound from nylon and its corresponding metal strings simultaneously. The combination of sounds from nylon and metal strings creates a single original sound, characterized by a deep, long lasting bright sound. This sound is different from the sound of a simple nylon string. Using it when playing a melody (accompanying only on nylon strings), the effect of sounding two instruments in one is achieved.

 On this instrument, an octave is played with one finger.

 This guitar can sound like a classic six-string guitar, as well as a traditional 12-string guitar, combining the quality of two instruments.

 A guitar may sound like an instrument "sitar" or like an "electric guitar." It can be played, including only on the strings of the upper 5th row, i.e., as on a classical guitar.

 Changing the methods of sound production in the right hand, you can play both single-voice and two-voice melodies without changing the technical performance of the left hand, alternate the number of sounds in the chord: from 3 to 6, from 4 to 8, from 5 to 10, and from 6 to 12.

 Thus, the invention extends the timbre and dynamic capabilities of a musical instrument.

 Industrial applicability.

 The invention is used in the manufacture of plucked string musical instruments, in particular, guitars.
