Description
Technical Field
The invention mainly relates to a music score explaining, displaying and controlling method, in particular to a split type color grouping electronic music score controlled by organ sound and a device.
Background
Music scores are methods of recording music with symbols. The traditional music score is recorded by printing or handwriting, and can record pitch or fingering, for example, recording the pitch of the music score comprises numbered musical notation, staff and dotted notation; the fingering six-line music score of a guitar and the abbreviated character music score of a guqin are recorded. In the computer age, music production has changed greatly, and electronic music scores have appeared. The forms of electronic music scores are more diversified, and besides the traditional electronic display of music scores, other recording methods, such as the MIDI standard for recording music in a data format, and gesture spectrums for directly showing gesture actions, have appeared.
However, the conventional music score needs to master the music theory and practice to read and understand quickly. Because the keyboard instruments such as the piano have more keys, the learning of various marks on the staff requires a long time for training, and for beginners of the keyboard instruments, the staff is difficult to directly correspond to the positions of the keys of the piano. The music originally aims to cultivate the sentiment of people and add life fun, but because the entrance of the keyboard musical instrument is high, people who do not have professional learning can hardly play piano music, and the piano playing mode becomes an entertainment mode which is difficult to reach and inconvenient for ordinary people to experience. In order to help beginners enter The door, some digital pianos (such as The one) or piano learning software push out gesture spectrums to visually display The playing gestures of players, but The beginners are difficult to follow The playing because keys are not distinguished on electronic music scores. Some digital pianos add indicator lights and control circuits on the piano keyboard, and control lights are turned on and off according to music scores to prompt players, so some changes need to be made to the piano body, and the method is not easy to be implemented on some traditional pianos. The 201610808301.6 patent proposes a dynamic form and meaning spectrum convenient for players to correspond keys to music scores, which is a vertical line spectrum corresponding to the keys one by one, notes are located on the vertical line spectrum, and white keys are marked in color, so that the keys are corresponding to the spectral line positions when the players play conveniently, but the white keys and black keys between different groups are still easy to confuse.
All notes of each vocal part of the traditional music score are displayed on one spectrum at the same time and played by one person; even when a plurality of persons play cooperatively, the music score is split according to the requirements of vocal music or the vocal parts. However, when a non-professional person or a beginner plays a piano, it may be difficult for one person to play the piano music alone, and each person has different abilities, so that it is desirable to play a part of the music score according to his abilities and preferences while practicing; when many people are played in a cooperative mode, the piano music can be freely split and independently displayed according to the ability and the preference of each person, and therefore the ensemble of the complete piano music can be easily completed.
In addition, when practicing playing, some operations, such as pause, fast forward, etc., are required to be performed on the played electronic music score. Electronic music scores equipped on a plurality of existing digital pianos have the operation functions, but a control circuit is required to be added on the traditional piano for control; the other type of the piano is controlled by human-computer interaction with a display screen for playing electronic music scores, although a hardware circuit is not required to be added on the piano, the human-computer interaction with the display screen in the playing process causes that the practice is not coherent enough and the operation is inconvenient.
If the spectral lines of the electronic music score can be in one-to-one correspondence with the keys, a beginner can conveniently map the music score to the positions of the keys directly, and the difficulty in playing of the beginner can be reduced; if can split whole electronic music book, form split type music book, cooperate the performance by several people simultaneously, then just can reduce the degree of difficulty of playing complete melody for amateur also can easily play the piano song, helps the piano to integrate into ordinary people's life amusement. Meanwhile, the sound control electronic music score is realized through the keys of the piano, so that the playing is more coherent.
Disclosure of Invention
All notes of the staff are on the same staff, and all notes are described by four lines, five spaces and lifting symbols, so that the interpretation needs to be trained for a certain time, the number of keys of the keyboard musical instrument is large, and a beginner cannot directly convert the staff into the keys. The invention aims to provide a split-body split-type color grouping electronic music score controlled by a piano sound and a device thereof, wherein the spectral line of the electronic music score directly corresponds to a piano key, the piano key and the piano key group are identified by colors or patterns, the electronic music score is simple and visual, can be freely split and combined, and an electronic display screen for displaying the electronic music score can also be split, combined and spliced, so that partial music score exercise or multi-person cooperative playing is facilitated.
A split type split color grouping electronic music score with sound control is provided, wherein spectral lines on the color grouping electronic music score are color spectral lines, and the spectral lines are vertical spectral lines corresponding to keys one by one. Keys on the keyboard musical instrument are grouped into one octave, spectral lines on the electronic music score are grouped into one octave-corresponding spectral line, the spectral lines in one group are different in color, and the color cycle of the spectral lines repeats after the next group of spectral lines. The notes are located on the spectral line, and the color of the notes is consistent with the color of the spectral line. To distinguish between different sets of spectral lines, the sets are again designated with different patterns or colors. The color grouping electronic music score is matched with a color grouping electronic music score, different colors are marked at the middle and upper positions of the entity keys, and the colors are consistent with the colors of corresponding spectral lines. By the next group, the color cycle of the color mark at the upper position in the key is repeated.

As the electronic score is played, the colored notes scroll down the color lines. On the electronic music score, a color key schematic diagram is drawn below a color spectral line, a keystroke time scale line is arranged above the key schematic diagram, and when a note rolls downwards and touches the keystroke time scale line, the key is prompted to be played. The length of each note along the line direction represents the duration, i.e., the pitch value, that the key corresponding to the note should be played. The score lines disappear when the note rolls down to exit the keystroke and the key may release. Taking a piano as an example, the piano generally has 88 keys, which are divided into 7 complete groups (one large character group, one small character group, two small characters, three small characters and four small characters) and two incomplete groups (two large characters and five small characters). The keys within one octave are 12 (7 white keys, 5 black keys) in a group. Then 12 spectral lines on the electronic music score are also in a group, different colors are used respectively, for example, 12 spectral lines corresponding to 12 keys of a small character group are respectively white, pink, rose red, orange, yellow, green, sky blue, dark blue, indigo, purple, brown and black, light pink is used as the background color of the group, the small character group is adjacent to the light pink, the spectral line color cycle is repeated, 12 spectral line colors corresponding to 12 keys of the small character group are respectively white, pink, rose red, orange, yellow, green, sky blue, dark blue, indigo, purple, brown and black, and light blue is used as the background color of the group. The upper middle position of a group of keys of small characters corresponding to the color grouping electronic music book is stuck with labels of white, pink, rose red, orange, yellow, green, sky blue, dark blue, indigo, purple, brown and black, and the key group is marked by a label of light pink above the keyboard of the group; on the small word group key that above-mentioned colored grouping electronic music book corresponds, the middle upper position is pasted white, pink, rose red, orange, yellow, green, sky blue, dark blue, indigo, purple, brown, black label, and this group keyboard top marks the musical instrument key group with light blue label.

And splicing all the sub-music scores to obtain the complete music score. For example, with 12 spectral lines of 12 keys corresponding to one octave on a key as a group, different groups of spectral lines in the color music score can be split to obtain a plurality of sub-music scores; the spectral lines of the same group can also be split into different sub-music scores; and different groups of spectral lines can be combined according to user requirements to obtain sub-music scores which are arbitrarily split and combined.
The device comprises a split type sound control device capable of grouping electronic music scores in a split type color mode, and the device comprises a processing module, a display module, a storage module, an interaction module and a pickup module. The display module is a detachable and assembled electronic display screen. The electronic display screens are used for displaying a plurality of sub music scores of the colorful electronic music scores respectively, the frames of the electronic display screens can be detached, the side edges can be spliced to form a wider screen and used for displaying the sub music scores obtained by arbitrary combination, and the electronic display screens are all spliced to display the complete colorful grouped electronic music scores. The processing module is used for controlling the work of each module, controlling the playing of the color grouping electronic music score and analyzing the idle keys of the current music score.
