In order to make the purpose, technical solution and beneficial effects of the present application more clear and more obvious, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Embodiments of a plurality of score comprehensive conversion methods and a comprehensive conversion system thereof of the present invention are described below with reference to the accompanying drawings.

Referring to fig. 1, a method for comprehensively converting a plurality of musical scores includes

The music semantic information in the method comprises musical scale and pitch information of a staff, basic element musical scale information is used as a horizontal object, pitch information is used as a vertical object, corresponding basic elements are selected through horizontal and vertical intersection points of different musical scales and pitch information, and then the selection required for conversion is carried out according to symbols corresponding to various spectrums in a conversion logic library corresponding to the basic elements; the basic element enables each converted spectrum to quickly and accurately determine the corresponding converted symbol.

When the staff to be converted is a picture, the step S1 of obtaining the staff and the music semantic information on the staff specifically includes:

acquiring a staff picture needing to be converted;

To further ensure the accuracy of the music semantic information and conversion, the method further comprises

And taking the generated staff as a comparison spectrum, comparing the comparison spectrum with the staff picture in terms of similarity rate, giving a warning if the similarity rate does not reach a standard value, identifying the converted fuzzy position on the staff, giving a note candidate symbol of the fuzzy position, and determining by user selection. Namely, whether the music semantic information of each note is accurate or not is supervised by comparing the overlapping rate of the staff converted by the music semantic information with the original staff picture.

Yet another method is to automatically identify the notes in the ambiguous locations according to the following method:

cutting the section where the note is located, forming a group by the note at the fuzzy position and the notes before and after the group, traversing the spectrum of the staff database according to the note symbols before and after the group, and acquiring a candidate group with the note symbols of the group; the staff database can be a staff database stored by local equipment or a staff cloud database;

In a specific example, the converted spectrum is a numbered musical notation; the converting the staff according to the conversion logic specifically comprises:

and (3) performing symbol display processing on the primary numbered musical notation: converting the time-reduced line, the sound-connected line and the half notes of the staff notes into the time-reduced line, the sound-connected line and the half notes in the form of the numbered musical notation at corresponding positions, as shown in fig. 2a and 2 b; the tone marks and the clef marks of the staff are not displayed at the corresponding positions of the numbered musical notation, which are shown in fig. 2c and 2 d; corresponding to the whole note symbols of the staff, the number of notes required to be displayed in the current bar is calculated according to the beat number of the current bar, the titles are displayed in the first position of the staff, and the later positions are filled up by transverse lines, as shown in fig. 2 e.

The rhythm comparison means that each line of music has a corresponding rhythm music for comparison, and teachers can teach students to sing music and beat to help students to learn. One example of the conversion of staff and numbered musical notation into rhythm notation is shown in FIG. 3; the conversion spectrum is a staff rhythm spectrum, rhythm notes of the staff are fixed at the pitch position of the same horizontal line and are represented by X; when the staff is displayed, the horizontal positions of the notes are not fixed, and the notes fluctuate up and down to cause a polyphonic line and a time reduction line to incline to a certain degree, but all rhythm notes after being changed into the rhythm music are at the same height in the horizontal direction, so that the inclination angles of the time reduction line and the polyphonic line are required to be processed horizontally to obtain the rhythm music of the staff;

The calling rhythm method in the actual operation process is executed as follows:

and after clicking a rhythm conversion button, calling a rhythm conversion method, judging whether the current rhythm conversion button is in a rhythm comparison state or not, and judging through a this.

Judging whether the code is in a rhythm comparison state or not, and executing a code in the form of if (is. isRhythm) { }; that is, if the program enters the interior of the judgment, it indicates that the program is currently in the non-contrast state, it needs to execute the logic of modifying the rhythm contrast spectrum, move all the positions of the notes to the same horizontal line, and modify the note exhibition state to the X exhibition.

And when the program enters into the else judgment, the comparison state is indicated to be in the current state, at this time, the comparison state needs to be cancelled, all the note positions are recovered to the positions of the normal notes through the for loop, and the X is converted into the normal note display.

Logic of fingering comparison: the method refers to how to operate other musical instruments to send the current notes, the playing musical instrument needs to press the corresponding sound hole, and how to press the hands when the sound hole is pressed, and fingering teaching can be used as a reference. FIGS. 4a and 4b show examples of converting spectra into fingered spectra; the converting the staff according to the conversion logic specifically comprises:

generating a fingering indication chart of each note according to the stored music semantic information syndromes and corresponding musical instrument playing logics in the conversion logic library, and arranging the fingering indication chart above or below the corresponding note for comparison and display; the fingering indication map comprises a fingering indication map of the wind instrument, and fig. 4a is a comparison schematic diagram after conversion of a staff notation and a bamboo flute fingering notation; also, for example, when the user selects the cucurbit flute, the corresponding note top shows the fingering of the cucurbit flute when the cucurbit flute emits the sound, as shown in fig. 4 b.

The fingering spectrum conversion method in the actual operation process is performed as follows:

starting to execute fingering display logic after selecting the corresponding musical instrument fingering;

and judging whether the fingering display state is in the fingering display state currently or not, judging whether the displayed fingering is the currently selected fingering or not, and if so, executing the logic operation of conversion between the staff and the fingering of the if.

In order to intuitively perform accurate performance through the fingering indicator graph and simultaneously perform the accurate performance without staff comparison, the embodiment further comprises the following methods: converting the fingering board into a reverse staff according to the conversion logic of the conversion logic library, comparing the reverse staff with staff, and distinguishing and recording the beat number and the connecting line of the reverse staff and the staff; and marking the obtained beat number and the connecting line on the corresponding fingering indication diagram according to the positions of the original upper part, the lower part or the left part and the right part of the note symbol. The method comprises the steps of directly judging the symbols wirelessly displayed in the fingering chart such as missing beat numbers, connecting lines and the like by reversing the comparison between the staff and staff, and then directly marking the symbols on the fingering indicating chart according to the original mode, such as directly marking the connecting sound line on the bottom of the corresponding fingering indicating chart.

The lyric contrast refers to the lyric display corresponding to each note. The difficulty of lyric input is to align the lyrics with the notes, that is, the space occupied by the time value of different notes is different, so the distance of each time of cursor movement needs to be calculated in real time according to the position of the note, and the operation is complex through the movement adjustment of the input cursor, therefore, the invention operates the words by the method of segmenting the words first. When the converted spectrum is a lyric comparison spectrum, the identifying and converting the note symbols on the staff according to the conversion logic specifically comprises:

inputting the whole lyrics in the input box of the lyrics;

and automatically generating a marked pinyin on the compared lyrics.

An example of lyrics displayed against a spectrum is shown in FIG. 5.

The invention also discloses a conversion method of the virtual keyboard comparison spectrum. The virtual keyboard contrast means that the virtual keyboard at the bottom can highlight the sound played by the current note when the note is played, so that a beginner can be helped to identify the approximate position of the current sound on the key. The identifying and converting the note symbols on the staff according to the conversion logic specifically comprises:

An example of a virtual keyboard against a spectrum presentation is shown in fig. 6.
