Bass is opened up the implementation method of the philharmonic sympathetic response musical instrument prolonged
Technical field:
The present invention relates to a kind of implementation method of orchestra, relate in particular to the implementation method that a kind of philharmonic sympathetic response and bass are opened up the orchestra prolonged.Belong to the national musical instruments field.
Background technology:
Along with the continuous propelling of China National orchestra " symphony " process, the bass part is as the pillar of sound equipment in band, and the basis of basic rhythm, play a very important role.Rich bass part is undoubtedly prosperity in counterpoint and strong embodiment.The sound equipment of bass part can make the rhythm of works carry out more firm, outstanding and understand, its powerful sympathetic response makes the whole acoustics of band be able to equilibrium.The bass part " is controlled " and band on certain level, is maintaining a kind of " order " in band, and modern nationality's orchestral music works are increasingly numerous and jumbled, there is no this " order ", and the body of knitting of musical works is difficult to the artistic effect that reaches plentiful, three-dimensional.So reform and research and development China National orchestra bass bowed instrument are important basic problems during national orchestra's " symphony " builds.Since the 1950's, China musical instrument fabricator, national musical instruments concert performers successively research and develop and produce the first generation and second generation bass bowed instrument---and " bass urheen " (recklessly low) and " the bass leather is recklessly ", this is that the national orchestra organizational system of improving Modern Significance has been brought into play positive facilitation.But the factor such as because audio frequency vibration is slow, volume is less, and tone color is low and deep, still have many national music ensembles to use Western violoncello and the contrabass bass part musical instrument as national music ensemble.This,, no matter from aspects such as external form or the warm property of tone color, also all exists the extremely inharmonic situation of the national style had with national music ensemble, does not fundamentally solve the problem of Chinese Musical Instruments " bass ".
Be in particular in the following aspects:
(1) from the developing history of traditional national music, various musical sound musical instruments are all self-existent with single form, or are wind instrument, or are stringed musical instrument.And the national musical instruments of philharmonic sympathetic response, unification also never had.Happy melodious novel national musical instruments that rouse oneself with string music in the urgent need to a collector exactly in the big family of the national orchestra of China.
(2) tone color between Chinese Musical Instruments or lay particular stress on high pitch or lay particular stress on middle pitch, differ greatly, but there is no so far the product of relative ideal for bass.
(3) in traditional China National orchestra, knit body because of the music of the popular single line bar of tradition, there is no functional harmony, there is no what is called " bass part ", therefore various musical instruments take play melody as many, do not have a kind ofly to take on specially that the bass master plays and the role's that accompanies musical instrument yet.Merge very much and there is " symphony " harmony support body language so national orchestra is difficult to play out tone color in the performance to musical works.
Summary of the invention:
The present invention is slow for the audio frequency vibration that solves current national bass bowed instrument existence, volume is less, tone color is low and deep, and utilize Western violoncello and the contrabass bass part musical instrument as whole philharmonic society, no matter this is from aspects such as external form or the warm property of tone color, all exist the extremely inharmonic problem of the national style had with national music ensemble, the implementation method of the philharmonic sympathetic response musical instrument that provides a kind of bass to open up to prolong, the method realizes by following step:
Utilize the aerophone Principles of Acoustics, design the sympathetic response attached cavity of tubulose qin bar as main organ for resonance qin cylinder; The string two ends are placed in respectively He Qintong lower end, tubulose qin bar upper end, by pulling the string of equal section on tubulose qin bar and qin cylinder, make main, attached organ for resonance produce three-dimensional resonance; Several mouths of raising one's voice that go out by master, the multi-direction seal cutting in attached organ for resonance surface again, further filtered audio frequency; Vibrations epithelium on the qin cylinder adopts artificial imitative sound epithelium design technology, the body integral material is made by narra for strengthening wooden density, tubulose qin bar and other national stringed instruments form unified sound equipment quality, realize musical instrument tonequality, volume and tone color harmony, to qin masthead end, processing is processed and is formed the hollow out diffusion type on this basis, and then resonance of the voice is discharged fully, form bass and open up the pipe prolonged, the novel sympathetic response musical instrument of string unification.
Characteristics of the present invention and beneficial effect:
The present invention is on the basis of traditional bowed instrument resonance of the voice feature, fully use modern musical instrument acoustic theory, fundamentally changed traditional bass Chinese fiddle and the structure of leather Hu using the qin cylinder as the organ for resonance single type, given prominence to the circular organ for resonance of main body (qin cylinder) and produced the three-dimensional design concept that resonates with the attached organ for resonance of tubulose (qin bar).Simultaneously, go out traditional seal cutting element pattern in main organ for resonance (qin cylinder) surface design, and hide several mouths of raising one's voice in pattern, the musical instrument audio frequency is further filtered, effectively subdue noise and noise, thereby guaranteed that tonequality, volume and tone color are more balanced and melodious.
Setting to effective range: the setting to effective range is the key of this problem development, embody " symphony " music thinking because the contemporary music works are outstanding and traditional single line bar musical features has larger difference, therefore, composer, conductor and players are also more and more higher to the requirement of musical instrument sound performance.Through the measuring and calculating of the science to the bass audio frequency, the range of the present invention of called after " Shu Geqin " is set in three and half octave range, that is: in one group of large word, large word group, small character group and one group of range scope of small character, wherein effectively playing range is C----a2.Improve violone tonequality, made it perfection incorporate band, can carry out solo by distinct personality again.Therefore, be no matter with six roots of sensation string or all can complete the performance demand of nearly all musical works with eight strings, and plentiful mellow and sturdy, the resonance vibration of bass area tone color and penetration power strong.
The requirement of tone color characteristics is simple and honest, solid, the sympathetic response sense is strong.The chances are adds the D0 of two lines under the staff bass staff for the limit double bass that at present orchestra exists, (showing it is the C of large word group on piano), limit descant adds the D0 (on piano show be the c of three groups of small characters) of two lines on the staff trble staff, centre four octaves of being separated by.According to the research and development concept of " Shu Geqin ", can reach the range requirement even exceeded in orchestra for the bass part fully.
Improve the poor inferior position of China National orchestra bass, we use for reference west musical instrument manufacturing technology (as principle of resonance, cavity body structure etc.), in conjunction with the Concrete Art form (as tone color, material etc.) of China national stringed instrument, thus form have distinct China National characteristic, bass area is plentiful and mellow sturdy, resonance sympathetic response and penetration power strong, large solid angle and and national musical instruments acoustic propagation, Shu Yage honor and philharmonic unification.
