Description
Technical field
The invention mainly relates to the corollary apparatus of keyboard instrument, and in particular to what a kind of rolling type musical alphabet and roll call were all shown
Device, and roll call changes with mode, device is placed on above key shoegaze and used.
Background technology
Keyboard instrument refers generally to piano, electronic organ etc..Piano is made up of key and metallic cord soundboard, and player is by pressing
Key on keyboard, the gavel that carpet is enclose inside piano is affected, then tap steel wire string and send sound, be mechanical device
Send sound.Piano determines that the frequency of each button on its keyboard is fixed by mechanical device to send sound, has solid
Fixed pitch.Pitch, refer to the height of sound, describe a kind of essential characteristic of sound, and the height of sound is determined by vibration frequency
, frequency Gao Zeyin " height ", on the contrary then " low ".Obviously, it is fixed that the pitch of piano key, which is nonadjustable, to adjustment
Professional piano tuner is also needed to adjust mechanical device.
In Musical System, 7 sound levels with independent names are called basic sound level, also referred to as nature sound level.Basic announcement
Level is with " C, D, E, F, G, A, B " seven letters represent, also referred to as the musical alphabet of basic sound level.Except basic sound level, also non-base
This sound level, is to be raised or reduced change by basic sound level, referred to as changes sound level, and its musical alphabet is：#C(bD)、#D
(bE)、#F(bG)、#G(bA)、#A(bB).It can be seen that musical alphabet as the name of people, is to define each sound level in music each
Title, it is the intrinsic attribute of each sound, belongs to this sound.White key and black key on fingerboard be according to
Fixed aligned transfer, each key has fixed pitch, white key contemporary music seven English alphabets " C, D, E, F, G, A, B "
(or its small letter) marks musical alphabet.The sound of this seven different height, the pitch distance between its adjacent tone, there is semitone and whole tone
Point, be half sound relationship between wherein E and F and B and C, be whole tone relation between remaining adjacent tone." C, D, E, F, G, A, B " this
When semitones change occurs for seven basic sound levels, if than original high semitone, with sharp (or liter mark) (#) represent；Than original
The flat come, with flat (or drop mark) (Ь) represent, " C, D, F, G, A " high semitone, its position is in basic sound level
On the black key on side, such as#C semitones higher than C, it is the black key after white key C.The constantly circulation of 7 basic sound levels repeatedly, is formed whole
The individual musical sound series of sound.It is referred to as one group to the series of sound its ottava alta C since C sounds.C sounds generally between bass staff the 2nd are opened
One group of sound being at first arranged in, marked with the small letter Latin alphabet c, d, e, f, g, a, b, claim small character group.7 white keys of small character group
Name (musical alphabet) be followed successively by " c, d, e, f, g, a, b ", the names of 5 black keys be followed successively by "#C,#D,#F,#G,#a”.Thus it is each upwards
Group claims one group of small character, two groups of small character etc. successively；Downward each group is marked with capital latin successively, claims big word group, big word one
Group, two groups of big word etc..The c that one group of small character is located on the central ledger line of great stave, therefore referred to as central C；Position on keyboard
Occupy center.
And roll call is the title sung spectrum for convenience when singing melody and used, it is a kind of call that people sing time spectrum, is
Can according to the change of the height or tune of sound and difference.Seven basic sound levels sing respectively work " duo, re, mi, fa,
Sol, la, si ", so that " 1,2,3,4,5,6,7 " this 7 Arabic numerals show in numbered musical notation.
White key and black key on fingerboard mentioned above be according to fixed aligned transfer, be according to twelve-tone equal temperament come
Design.88 keys are divided into bass area, middle register and treble, then are grouped on this basis.As again middle register is divided into three
Group：Two groups of small character group, one group of small character and small character, every group is an octave, there is 12 keys, wherein 7 white keys, 5 black keys, this
12 keys are 12 sounds used in twelve-tone equal temperament, its corresponding musical alphabet for " C,#C, D,#D, E, F,#F, G,#G, A,#A,
B”.And an octave only has 7 roll calls in numbered musical notation, it is seen that 12 keys of an octave group on fingerboard, and 7 roll calls
It is unlikely to be fixed corresponding relation.Which musical alphabet key is determined as " duo " (digital " 1 ") by song mode, and is connect down
6 sounds come " re, mi, fa, sol, la, si ", are adjusted for the piano for having been set to twelve-tone equal temperament and by song
Formula determines, once have selected the mode of playing of song, then 7 roll calls are just and in 12 keys of an octave group on fingerboard
7 keys one-to-one relation is determined.As can be seen here, for piano, an octave group on its keyboard has 12 keys,
Then there are 12 kinds of modes, because 12 keys can act as " duo ", and 7 keys corresponding to 7 roll calls of every kind of mode are not
Fixed, it is that roll call corresponding to piano key is not fixed, becomes with mode.Such as, adjusted and played on the music score of Chinese operas then with C
Can indicate and play mode " 1=C ", now by " C, D, E, F, G, A, B " musical alphabet key come correspond to roll call " duo, re, mi, fa, sol,
la、si”；And work as " 1=#F ", it is to play#The big timings of F, be again by "#F、#G、#A、B、#C、#D, F " musical alphabets key represents respectively sings
Name " duo, re, mi, fa, sol, la, si ", it is seen that roll call corresponding to piano key is not fixed.
It can be seen that musical alphabet and roll call are had any different and contacted：1) musical alphabet has 12；2) roll call only sings 7, i.e., only sing " 1,2,
3,4,5,6,7 " this 7；3) musical alphabet roll call is not corresponding to fixation, and e.g., musical alphabet " b " key in one group of small character represents in C tune
Roll call " 7 ", roll call " 4 " is represented in F tune；4) musical alphabet is changeless that roll call converts at any time according to mode.By C pairs of musical alphabet
Roll call " 1 " is answered, as C is adjusted, musical alphabet#A corresponds to roll call 1, as rises A and adjusts or drop B to adjust.
It is not fixed just because of roll call corresponding to piano key, becomes with mode, for piano beginner
For be difficult corresponding position of piano key is found according to the roll call of humming.When playing, typically played according to staff
's.Staff describes pitch between five lines and four, is the height for being easy to show sound relative to numbered musical notation, the advantages of staff, but
It is that staff does not have cycle specificity, is not based on roll call design, it is difficult to hum out roll call between five lines four, is unfavorable for
Sightsinging.If roll call also has 12, numbered musical notation is also corresponding with 12 grades, can be corresponding with 12 keys of one octave of piano, such musical alphabet
Roll call can just match corresponding.In addition, if the device for marking for having a musical alphabet roll call can be according to mode 12 grades of this numbered musical notation and steel
Qin key is corresponding, then sightsings and find position of piano key beneficial to player.
