Description

A kind of new trichord

Technical field

Musical instrument technical field is the utility model is related to, specially a kind of new trichord.

Background technology

Trichord：Also known as " three-stringed plucked instrument ", Chinese Han nationality's tradition plucked instrument, gained the name because there are three strings, other ethnic groups By Han nationality's cultural influence, also there is the musical instrument of similar trichord.Handle is very long, and audio amplifier justifies square, two sides covering, three, string, and side is embraced in bosom Play, tone color is rough, bold and unconstrained, can be commonly used to national instrumental music, local opera music and Chinese musical telling music with solo, (instrumental) ensemble or accompaniment.By Different geographical, nationality and cultural custom emphasis influence, and trichord always has a variety of shapes, can substantially be classified as large and small two kinds of trichord.

After the 1950s, some musical instruments improvement man and trichord concert performer are changed on the basis of both trichord It is good, obtain very ten-strike.The construction of trichord is simpler, can be divided into scroll head, rod and qin drum three parts, by scroll head, peg, mountain The compositions such as mouth, rod, drum frame, epithelium, bridge and string.Scroll head is in spade more, is the decorative parts of trichord, is typically all embedded with bone Flower undercuts decorative pattern, and string slot is outputed in centre, and groove side is provided with peg hole, and three pegs are placed in scroll head both sides.Rod is semicircular Column, smooth surface are the fingerboards of trichord, and upper end is embedded with mountain pass, and lower end is square in insertion qin drum.Qin drum is called drum Or drum head, be trichord resonant tank, it be on the drum frame of somewhat elliptical shape two sides cover formed with boa skin.Bridge is placed in boa skin Centre.String uses silk string or steel wire string, is followed successively by exterior string, middle string and the thicker inner string on the huqin from high pitch string, exterior string fine silk strings used for the outer strings, and middle string is with two String, thicker inner string on the huqin the thicker inner string on the huqin.One end of three strings all ties up to qin and roused on following rhombus wood shell, and the other end is respectively wound on three strings On axle.

For existing trichord after a period of time is played, there is pine because progressively being loosed elastic force by relaxation power for a long time in string Relaxation phenomenon, the method for existing regulation string elastic force is more complicated, need to also be by extraneous instrument, therefore its efficiency comparison is low.
