Description
Technical Field
The invention mainly relates to a matching device of a keyboard musical instrument, in particular to a scrolling type device for displaying both a note name and a singing name, wherein the singing name changes along with the mode, and the device is placed above a piano playing musical instrument.
Background
The keyboard musical instrument generally refers to a piano, an electronic organ, or the like. The piano is composed of keys and a metal string soundboard, and a player pushes the keys on the keyboard to drive a small mallet covered with a felt in the piano, and then strikes a steel wire string to make a sound, so that the mechanical device makes a sound. The piano sounds by mechanical means that determine the frequency of each key on its keyboard to be fixed, with a fixed pitch. Pitch, which is the height of a sound, describes a basic characteristic of the sound, and the height of the sound is determined by the vibration frequency, and the frequency is high, the sound is high, and the frequency is low. Obviously, the pitch of the piano keys is not adjustable and fixed, and a professional piano disc jockey is required to adjust the mechanical device.
In the musical tone system, 7 sound levels having independent names are called basic sound levels, which are also called natural sound levels. The basic scale is represented by seven letters "C, D, E, F, G, A, B," also known as the pitch name of the basic scale. Besides the basic sound level, there is also non-basic sound level, which is obtained by increasing or decreasing the basic sound level, and is called as the variable sound level, and the sound name is:#C(bD)、#D(bE)、#F(bG)、#G(bA)、#A(bB) in that respect It can be seen that the pitch name, like the name of a person, is the name that defines each level of the music, and is the inherent attribute of each pitch to which it belongs. On piano keyboardThe white keys and black keys of (1) are arranged in a fixed pattern, each key having a fixed pitch, and the white keys of modern music are assigned a phonetic name by seven english letters "C, D, E, F, G, A, B" (or their lower case). The pitch distance between adjacent sounds of the seven different high and low sounds is divided into semitone and whole tone, wherein E and F are in semitone relationship, B and C are in whole tone relationship, and the rest adjacent sounds are in whole tone relationship. When the seven basic tone levels of "C, D, E, F, G, A, B" have semitone changes, if the semitone changes higher than the original semitone, the symbol (or "ascending symbol") is used (#) Represents; for bass than the original, by a symbol (or called as "JianЬ) High demiphones, representing "C, D, F, G, A", are positioned on the black keys beside the basic level, e.g.#C is a higher semitone than C, and is a black key after the white key C. 7 basic sound levels are repeated continuously and circularly to form the whole musical tone array. The columns of tones starting from the C tone to its upper octave C are called a group. A group of tones, usually arranged starting with the C-tone in Bass Table 2, is marked with the lower case Latin letters C, d, e, f, g, a, b and is called a small character group. The names (sound names) of 7 white keys in the small character group are ' c, d, e, f, g, a and b ' in turn, and the names of 5 black keys are ' in turn "#c，#d，#f，#g，#a' is obtained. Therefore, each group is called as a small character group, a small character group and the like in turn; downward groups are marked by capital Latin letters in turn and are called big character groups, etc. C of the small word group is positioned on the central plus line of the large staff, so the small word group is called as central C; the location on the keyboard is also centered.
The singing name is a name adopted for facilitating the music score when the melody is sung, is a calling method when people sing the music score, and is different according to the tone of the music or the change of the tone. Seven basic levels are sung as duo, re, mi, fa, sol, la, si respectively, and are represented by 7 arabic numerals of "1, 2, 3, 4, 5, 6, 7" in the numbered notation.
It is mentioned that the white keys and black keys on the piano keyboard are arranged according to a fixed rule and are designed according to the twelve tone law. The 88 keys are divided into a bass region, a middle-pitched region and a treble region, and are grouped on this basis. Such as a mediantThe zones are again divided into three groups: small character group, small character group and small character group, each group is an octave, there are 12 keys, 7 white keys and 5 black keys, these 12 keys are 12 tones used by twelve equal temperaments, their correspondent tone name is "C,#C，D，#D，E，F，#F，G，#G，A，#and A and B'. While one octave has only 7 note names in the numbered musical notation, it can be seen that 12 keys in an octave group on the piano keyboard and 7 note names cannot be fixed corresponding relations. Which note name key is regarded as "duo" (numeral "1") is decided by the track pattern, and the next 6 notes "re, mi, fa, sol, la, si", are also decided by the track pattern for the piano that has been set to twelve equal temperaments, and once the playing pattern of the track is selected, the 7 note names determine a one-to-one correspondence with 7 keys in an octave group of 12 keys on the piano keyboard. It can be seen that for a piano, there are 12 tones of 12 keys in an octave group on the keyboard, because 12 keys can be regarded as "duo", and 7 keys corresponding to 7 song names of each tone are not fixed, that is, the song names corresponding to the piano keys are not fixed and are changed with the tone. For example, when the C key is used to play the music score, the playing style "1 ═ C" is noted, and the "C, D, E, F, G, a, B" note name keys "duo, re, mi, fa, sol, la, si" correspond to the song names; and when "1 ═ is#F', namely playing#When the major key is F, it is composed of "＃F、＃G、＃A、B、＃C、#D. F ' tone name keys respectively represent the song names ' duo, re, mi, fa, sol, la and si ', and the song names corresponding to the piano keys are not fixed.
It can be seen that the sound name and the singing name are distinguished and related: 1) the number of the phonetics is 12; 2) only 7 singing names, namely only 7 singing of 1, 2, 3, 4, 5, 6 and 7; 3) the phonetic name and the vocal note name are not fixedly corresponding, for example, the key of the phonetic name 'b' in the small character group represents the vocal note name '7' in the C tune, and represents the vocal note name '4' in the F tune; 4) the sound name is fixed and invariable, and the singing name is changed at any time according to the tone. The sound name C is corresponding to the singing name '1', namely the tone C, the sound name#A corresponds to the record 1, i.e. it is the tone of Sheng A orRegulate blood sugar and blood sugar.
Just because the corresponding singing name of a piano key is not fixed and is changed along with the mode, it is difficult for a piano beginner to find the corresponding key position according to the singing name of humming. When playing, the musical instrument is generally played according to a staff. The staff describes the pitch by the five lines and the four lines, and compared with the numbered musical notation, the staff has the advantages that the pitch is easy to show, but the staff does not have cycle characteristics, is not designed based on the singing name, is difficult to hum the singing name in the five lines and the four lines, and is not beneficial to reading and singing. If there are 12 note names, the numbered musical notation also corresponds to 12 grades, and can correspond to 12 keys of one octave of the piano, so that the note names can be matched and correspond to one another. In addition, if a marking device with the name of the note can correspond the 12 grades of the numbered musical notation to the piano keys according to the mode, the player can see and sing and find the positions of the keys conveniently.
