Description
Technical field
The invention mainly relates to the devices of multiple electronic score machines, and in particular to one kind is with commander and electronic score function
Electronic command music score of Chinese operas unit installation.
Background technique
Group's musical instrument association play be mankind's musical life common form, the band that feature is made of a variety of musical instruments, by one
Fixed time rhythm plays the music score of Chinese operas of different parts, and also there is large-scale professional philharmonic society (such as symphony in existing small-sized amateurish band
Philharmonic society).In general, each musician requires a music score of Chinese operas, and the music score of different musical instruments is not quite similar.Group's musical instrument association
It plays and each musician is required to play in strict accordance with the rhythm note that the music score of Chinese operas indicates with value (i.e. note duration), i.e.,
Current moment must be gone out in strict accordance with note as defined in the music score of Chinese operas and its duration synchronizes performance, even half mistake clapped
It will affect performing effect.Since each musician feels to be not quite similar to rhythm and value, it is difficult to accomplish synchronous performance, especially
It is for team is played music by sparetime association.In order to solve this problem, professional symphony orchestra is to command difference by conductor
Synchronous performance between musical instrument.The cammander of the group of playing music of association both should be clearly understood that the performance start/stop time and rhythm of different musical instruments
Etc. information, while also these information are accurately transferred to each musician by body languages such as gestures.Therefore happy to group
Device association plays for (especially large-scale philharmonic society), it is necessary first to a conductor with good musical quality, abundant body language,
Also require each musician that can play in strict accordance with the instruction of conductor simultaneously.
When association plays, on the one hand musicians will see the music score of Chinese operas, and the gesture that on the other hand abide by commander is played.Traditional
The music score of Chinese operas is usually paper printing spectrum, needs to carry out manual page turning, this can add to musician when playing and bother.It is happy for the sparetime
For hand especially beginner, even solo, the manual page turning of the music score of Chinese operas is also a burden.Such as it plays the piano or bullet is ancient
Zither, beginner generally require to stop playing during playing, could compose to qin and carry out page turning, very influence playing state, drop
Low learning efficiency.
One is assisted team of playing music to generally comprise a variety of musical instruments.By profession symphony band for, usually by string music, wind instrument,
The part of percussion music difference tone color forms, and generally there are 20-30 musicians in small-scale symphony orchestra, and large-scale symphony orchestra drills
Battle array is then up to over one hundred people out.It is conceivable that for the band of a up to a hundred people, if different Instrumentalists pell-mell divides
Different zones are dispersed in, a conductor is difficult to command them.Therefore, it in symphony orchestra, plays similar
The musician of musical instrument concentrates on a region and towards conductor.The seat of different musical instrument musicians is arranged, then is sound to be considered
The happy overall effect played.By practicing for a long time, team is performed in professional symphony in the world, follows similar seat mostly
Position arrangement principle.For example, string music group is the basis of entire symphony orchestra, its tone color gives cordial feeling, so general seat
It comes before stage, near spectators.Wooden pipe group musical instrument type is more, and tone color is prominent, so needing it categorizedly
It is arranged in after string music group, the intermediate position of band.Brass instrument and percussion instrument, volume is grand, and rich in irritation, so
They be arranged in band backmost or trailing flank.Harp and other plucked instruments often come the left and right sides of band.Certainly, this
Nor absolute, there is relationship with the works of performance and the personal preference of conductor.For example some modern and contemporary send composer's
Works are played, and the seat arrangement of band may have certain special arrangement.
Due to the presence of cammander, player must face cammander when association plays.It is envisioned that if you do not need to commander
Person, then the arrangement of musician can be more diversified.It is many times exactly not command such as in the association of traditional Chinese musical instrument plays
, therefore can accomplish folk music characteristics strong, different from foreign music.Why also can be carried out association without commander to play,
It is relatively few because of the instrument type played, and some performance period is added based on certain kind musical instrument (it gives great volume a bit)
Upper player cooperates for a long time, does some training very often.National orchestra of China has drawn the advantages of each kind musical instrument combines in traditional pleasure kind,
Situations such as according to the performance, feature and tone color of national musical instruments, and in view of the cooperation of high, medium and low part and balanced, the sound of volume
The factors such as the coordination of color, generally comprise four musical instrument groups: happy group of blowpipe plays happy group, happy group of string pulling, percussion music group.
Vast Amateur Music fan be also delithted in fact group deduction, " square dance " such as to sweep the country, be exactly with
Group's neat and consistent is beauty.But in musical instrument, association is played, and Amateur Music fan is to be difficult to realize more musical instrument associations to play.In addition, more sound
Portion's choir is also relatively difficult.Its reason first is that be difficult to find that suitable cammander, can especially command multi part
More instrumental musics, which are sung, plays mashed up commander；Second is that for many Amateur Music fans, on one side see the music score of Chinese operas, while see the hand of commander
It is highly difficult that gesture, which play,.If Amateur Music fan also can easily carry out, and more instrumental music associations play and multi part closes
It sings, then must can enrich the free life of broad masses of the people, promote national public physical and mental health.
Currently, being improved in the papery of the music score of Chinese operas, there is electronic score and electronic score bench, mainly the music score of Chinese operas is become
At electronical display, be not necessarily to manual page turning, liberate the both hands of player, as patent " a kind of foot-controlled electronic notation table " (application number:
CN201120325379.5) and " electronic music stand " (application number: CN201120022924.3) is just by foot pedal come page by page
Turn over spectrum.Patent " band electronic music score rack control service system " (application number: CN102238147A) can also provide the same of electron Spectrum
Page turning or synchronous mark are walked, which sends the music score of Chinese operas from philharmonic society's music score of Chinese operas library using existing computer network by control terminal
To route terminal, electronic score bench arrives route terminal downloading again；The synchronization page turning of its electron Spectrum or synchronous mark are to pass through UDP
Multicast is realized in a musical instrument group.As it can be seen that electronic score is development trend, if can also be in entire philharmonic society in addition to synchronous page turning
The simultaneous display music score of Chinese operas in (band) would be even more beneficial to the synchronous of all musicians and play.In addition, if synchronization system is independent of existing
Fixed computer network will promote the synchronizing quality of each electronic score bench, and indoor performance is also beneficial to be extended to family
Outside, the different formation of layout.
In view of this, the present invention proposes a kind of electronic command music score of Chinese operas unit installation based on synchronization field from broadcast, to form
One synchronization field, synchronization field refer to the territorial scope that several electronic score machines are put, and electronic score machine within this range can
