The quick calculating disc of chord of the present utility model is used " the first note spectrum of transferring of numbered musical notation ", and it has following several functions;
One, front; Play all kinds of and people acoustic musical instrument, coil with this; Can extrapolate big accent fast, the tonic chord of any one accent of ditty belongs to chord, subordinate's chord, and the title of dominant seventh chord.Do not spend and memorize mechanicallyd.
Two, back; Though the man who loves to singing can identification of spectrogram, and music theory is known nothing, and coils with this; Can extrapolate the tune that the own voice of best-fit is sung fast, so that tell that band is the just right tune of oneself accompaniment.
Three, this dish particularly suitable is begun to learn the guitar fan and is calculated each big accent, the reckoning of ditty chord name.Method is very simple.The breach of rotation [the string function that respectively is in harmonious proportion recruit dish] just can be seen the big accent that you want, ditty, tonic chord, subordinate's chord, genus chord and dominant seventh chord title.The center of breach " up and down " is to be in harmonious proportion the ditty tonic chord greatly, and the limit that keeps left be to be in harmonious proportion subordinate's chord of ditty greatly, the limit of keeping right be to be in harmonious proportion the genus chord of ditty greatly, and dominant seventh chord.96 chord names in 12 accent need not tax one's brains to parrot and remember firmly.Reading the Tape gets final product, convenient being suitable for.
Although the people who four, plays rhythm instrument is without chord, " roll call and the musical alphabet contraposition " that can calculate each accent with [voice and the song set the tone fast device] of musical alphabet dish and roll call dish composition fast is any musical alphabet, can learn to strengthen the understanding to each pitch names.Be ignorant of the people of music theory, if you ask, and his E transfers 6 is what musical alphabet, and he can not give the answer, and has been readily solved once rotating with this dish.
Six, this dish small gap place, back, with the flat that rises of the staff of 12 accent, the musical alphabet that " do with reference to " rotates the front and roll call contraposition can find out each increase flat how much and lifting those musical alphabets,
C transfers not have and rises flat, and G transfers a sharp, and D transfers two sharps, and A transfers three sharps, and E transfers four sharps, and B transfers five sharps, and #F transfers six sharps, and #C transfers seven sharps, and bA transfers four flats, and bE transfers three flats, and bB transfers two flats, and F transfers a flat.
Be below; Voice and the song dish chord of setting the tone fast calculates that fast the usage, basic music theory of device explain; And the example that lives through of the folk music of I decades.
Six accent examples not too commonly used; E, A, B, #F, #C, #G transfer, and allow him although the Amateur Music fan has played 30 years musical instruments, she says subordinate's chord of one of them interior accent of six accent wherein being of little use, the dominant seventh chord title he, they differ and answer to such an extent that come up surely.Method simple [12 mediation string name pans of a steelyard] just can solve, and allows it answer this problem.Amateurish troupe, the people of object for appreciation rhythm instrument, he, they pay attention to roll call, but think little of the research of musical alphabet.Violin, Lei Qin, bowed instrument, urheen kind, monochord, trichord all is the musical instrument that does not have product, as; Determine musical alphabet with trichord, playing is what roll call of that accent, and finger is pinned the roll call phoneme of playing, and blows [voice with song set the tone fast dish] " head accent singing style " tuner pipe identical with roll call, has just known the musical alphabet at that seat of pinning.The position of musical alphabet on each kind musical instrument fixed just as people " surname ".And roll call changes just as the work post.Move.Rotate the roll call dish and just found out the variation of it and musical alphabet.
12 big accent of music, 12 ditties, each accent has tonic chord, and subordinate's chord belongs to chord, dominant seventh chord, the most basic chord amounts to 96 chords.[ninth chord above and the Pentatonic chord do not relate to] level of common people do not learn music theory, most music theorys that all are ignorant of add the chord conversion, inversion of a chord is just more muddled.Must say what long time was all not necessarily come to understand as if say music theory to them.
Need not to go into seriously music theory with this instrument, the man who loves to singing just can make the tune that the own voice of best-fit is sung fast.[12 be in harmonious proportion string name pan of a steelyard] can select in 12 accent that you will find eight chord names in any one big accent wherein.
Above binomial function, this instrument can be selected in three seconds.
It is that ' what accent ' found out the song descant that will sing [point of note top be need not to consider that the man who loves to singing at first will go out descant to the voice school, roll call is that descant gets final product] singer can not have under the situation of musical instrument, calculate the accent that is fit to own voice with [voice and song set the tone fast dish], give song recitals with the tuner pipe accordatura on the dish, performance fore blow once tuner pipe is done with reference to sound.Example; The highest F of being of voice sings that ' where dare to ask the way, this song descant is 1, blows D when singing and be exactly that F transfers 6, the lyrics; You jump load [you] is note 6, and not wanting such this first song that you sing out of tune when singing is exactly that F has transferred.In the world have only mother good, and where dare to ask the way, method is identical.
Example; Someone voice descant is that G will sing; Ship well; This song descant is 3, with 3 relative with G, looks for 1 then, and the musical alphabet relative with 1 is that this accent of bE is exactly that the best has been transferred.Example; Someone voice descant is that A will sing; Mother, descant of this first song is 3, with 3 couples of A see then 1 with the musical alphabet contraposition be what musical alphabet? so with 1 contraposition be F, so; Mother; This first song A transfers voice just to sing best, efficient and convenient with the F accent.Just right.Band among the people, song-and-dance duet and small towns the man who loves to singing sang for three more than ten years, a lot of people all be do not know with what transfer the most suitable I oneself, all be that band recruits for them.I have lived in Heilungkiang and had seen picture in 40 years; Ma Guangfu, such people are a lot.Some old artists among the people suona horn a lifetime of haveing broken up in 78 years old blow pretty goodly, but he does not know to have the notion of " chord " unexpectedly, and method simple [song set the tone fast device, chord is calculated device] is made learning tool and just can be solved he, their this problem.
Have in the community a lot of singings sing good crowd, but all be ignorant of music theory, can not calculate accent, be not high, be exactly low, and do not reach best singing effect.He, they know 1234567, but not too know CDEFGAB and liter, flat.
Be the more first ABCs of transferring of numbered musical notation below;
The numbered musical notation movable do;
1 bucket 2 burns for 3 meters 456 and draws 7 to carry
The numbered musical notation musical alphabet;
C west D ground E justice F husband G season A sound of sighing B coin
Musical alphabet has M to represent minor triad, and the musical alphabet that does not have M is a Major chord, and b represents flat, and # represents sharp, and seven represent dominant seventh chord.
Example; This symbol bB cries and falls coin, and this symbol rises the west #C, etc.
Musical alphabet, the lifting of roll call all is the relation that height equals mutually;
#C=bD, #D=bE, #F=bG, #G=bA, #A=bBbD=#C, bE=#D, bG=#F, the lifting relation of bA=#G.bB=#A roll call and musical alphabet also all is the same.
#1=b2, #2=3, #4=b5, #5=b6, #6=b7b2=#1, b3=#2, b5=#4, b6=#5, b7=#6 illustrates; The big mediation that 1=C transfers concerns eight chords of A ditty.
