[0030] The embodiments of the present application will be described in detail below with reference to the drawings.

[0031] It should be clear that the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0032] The following will be described in combination with the drawings Figure 1The scheme provided by the embodiment of the present application is described in detail, Figure 1 A flowchart of a method for drawing sheet music provided by the embodiment of the present application is shown in FIG. 1. In the embodiment of the present application, the main body is a terminal, such as a desktop computer, a personal PC, a PAD, and the like. As shown in FIG. 2, the method of the embodiment specifically includes the following steps: Figure 1

[0033] Step 110, obtaining first sheet music data in XML format;

[0034] Specifically, the terminal obtains first sheet music data, which is specifically in XML format. It can be understood that the sheet music data in XML format is a standard format sheet music data in the prior art. For example, part of the sheet music data given below is in XML format.

[0035]

[0036]

[0037] As can be clearly seen from the above structure, the first sheet music data in XML format conforms to the standard sheet music making habits, and has high readability after the meanings of the above-mentioned attributes are determined.

[0038] Step 120, converting the first sheet music data into second sheet music data in original JSON format;

[0039] Specifically, after the terminal obtains the first sheet music data in XML format, the first sheet music data is converted into second sheet music data in original JSON format.

[0040] In this step, the terminal does not change the overall structure of each attribute included in the first sheet music data in XML format in the process of converting the format of the sheet music data, but only converts the format.

[0041] Step 130, extracting sheet music attribute elements from the second sheet music data;

[0042] Specifically, after the terminal obtains the second sheet music data in original JSON format, the sheet music attribute elements are extracted from the second sheet music data.

[0043] For example, the sheet music attribute elements can be specifically as follows: <key> 、 <time>、 <clef> 、 <system-margins>and so on.

[0044] Step 140, generating third music score data with final JSON format according to the music score attribute element;

[0045] Specifically, after the terminal acquires the music score attribute element, different initial structures are generated according to the types of the music score attribute element. Each initial structure is iterated repeatedly to obtain different final structures. The terminal combines different final structures as the third music score data with final JSON format.

[0046] Optionally, the music score attribute element includes music score basic data, format coordinate data and music score playing data.

[0047] Optionally, the terminal generates the third music score data with final JSON format according to the music score attribute element, and specifically includes:

[0048] The terminal acquires the music score basic data from the music score attribute element. The music score basic data can be specifically the basic data of measures and notes in the music score. According to the acquired music score basic data, the terminal generates the corresponding initial parts structure.

[0049] It should be noted that in the process of generating the initial parts structure, part of the data may be lost, or due to the XML format, the music score basic data may have problems of overlapping, coordinate error, etc. when converting the original JSON format. Therefore, after the terminal generates the initial parts structure, the initial parts structure is processed to obtain the processed parts structure.

[0050] In the embodiment of the application, the terminal performs error correction processing on the initial parts structure, which can be specifically that the terminal reacquires the music score basic data from the second music score data in the original JSON format, and repeatedly executes the process of generating the initial parts structure to obtain the processed parts structure.

[0051] The terminal judges whether the processed parts structure conforms to the preset structure. If not, the terminal repeatedly executes the process of acquiring the music score basic data from the second music score data to judging whether the processed parts structure conforms to the preset structure until the processed parts structure conforms to the preset structure, to obtain the final parts structure.

[0052] The preset structure can be specifically a structure in which the processed parts structure does not have problems such as data loss, data overlapping, coordinate error, etc.

[0053] The terminal obtains score playing data from the score attribute element. The score playing data can be time-related information. According to the obtained score playing data, the terminal generates a corresponding initial timeline structure.

[0054] It should be noted that in the process of generating the initial timeline structure, part of the data can be lost, or due to the XML format, the score playing data can overlap or have coordinate errors when converting the original JSON format. Therefore, after the terminal generates the initial timeline structure, the terminal performs error correction processing on the initial timeline structure to obtain a processed timeline structure.

[0055] In the embodiment of the present application, the terminal performs error correction processing on the initial timeline structure, which can specifically be that the terminal re-obtains score playing data from the second score data in the original JSON format, and repeatedly performs the process of generating the initial timeline structure to obtain the processed timeline structure.

[0056] The terminal determines whether the processed timeline structure conforms to a preset structure. If not, the terminal repeatedly performs the process of obtaining score playing data from the second score data to determining whether the processed timeline structure conforms to the preset structure until the processed timeline structure conforms to the preset structure, to obtain a final timeline structure.

[0057] The above-mentioned preset structure can specifically be a structure in which the processed timeline structure does not have problems such as data loss, data overlap, or coordinate errors.

[0058] In the embodiment of the present application, the timeline structure includes span data, that is, a time span. It is related to the measure included in the parts structure, that is, the measure in the score, but not in a one-to-one correspondence. Similarly, the point (time point) and element (performance element) included in the span data are also related to the notes in the score, but not in a one-to-one correspondence.

[0059] In addition, in the parts structure, various pre-computations are performed. For example, the positions of notes, the relative positions of various notations, and the like can effectively improve the runtime efficiency. Furthermore, the relationship between each score basic data and the notes and measures is reorganized. According to the drawing relationship, rearrangement is performed, such as tie (same sound connection) and tuplet (three consecutive sounds), which are notation subordinate to notes, but also have an impact on other notes. Data will be recorded and processed in the manner of being subordinate to the direction of the measure.

[0060] The terminal obtains format coordinate data from the score attribute element. The format coordinate data can specifically be coordinate-related information of score drawing and printing. According to the obtained format coordinate data, the terminal generates a corresponding final system structure.

[0061] For example, the format coordinate data can specifically be a margin of score printing on paper, a distance between scores, and the like.

[0062] The terminal assembles the final parts structure, the final timeline structure, and the final system structure into third score data in a final JSON format.

[0063] For example, part of the score data given below is in a final JSON format.

[0064]

[0065]

[0066] As can be clearly seen from the above structure, the final JSON format completely sacrifices readability and is designed entirely around the flexibility and efficiency of a program.

[0067] For example, part of the score data given below is in a final JSON format.

[0068]

[0069]

[0070] As can be clearly seen from the above structure, the final JSON format divides a score into three large modules, namely, a final parts structure, a final system structure, and a final timeline structure. By obtaining data belonging to the parts structure, the system structure, and the timeline structure from an XML format, respectively, and recombining the logical relationship between the data, different requirements can be easily achieved from one piece of score data.

[0071] Step 150, inputting the third score data into a score block generator, so that the score block generator displays corresponding score according to different scenarios.

[0072] Specifically, after the terminal obtains third score data in a final JSON format, the terminal inputs the third score data into a score block generator, and the score block generator displays corresponding score according to different scenarios.

[0073] The score block creator is an OpenGL-based MusicJSON drawing tool for displaying and using a score. The score block creator includes three types of score blocks. The first type of score block is a standard format score block, corresponding to a traditional scenario. The second type of score block is an equidistant format score block, corresponding to a uniform scrolling scenario. The third type of score block is a split format score block, corresponding to an independent special effect scenario.

[0074] In the embodiments of the present application, the three types of score blocks are specifically system block division, span block division, and time point block division. The three types of block division can flexibly meet the needs of various use scenarios.

[0075] For example, the system block division is similar to the standard score format, which is equivalent to the drawing method of a traditional score. The span block division can display a score based on a certain performance time through equidistant arrangement, which is used for a scenario requiring uniform scrolling playback. The time point block division is used for further splitting a score, which can realize independent playback of various special effects based on score basic data.

[0076] The terminal can select a matching score block from the score block creator according to a user selection, and generate a corresponding score from the matching score block.

[0077] Optionally, the terminal inputs third score data to the score block creator, so that the score block creator displays a corresponding score according to different scenarios. Specifically, the terminal inputs the third score data to the score block creator. The terminal receives a first selection instruction input by a user, the first selection instruction being used for selecting a matching score block from the score block creator. According to the selected score block, the terminal generates a corresponding score.

[0078] Optionally, on the basis of each block division, each block division additionally provides various interfaces to receive further processing of a score by a user. For example, changing the color of a note, changing the display style of a note, changing the coordinates or movement mode of each note, changing the display range of a score, and the like. The above processing can make the score have more expressive power.

[0079] The terminal receives a second selection instruction input by a user, the second selection instruction being used for changing the display mode of a score and the movement position mode of elements included in the score. According to the second selection instruction, the terminal processes the display of the score and the movement position of the elements.

[0080] It should be noted that during the execution of the foregoing steps 110-150, the terminal can also use other related tools to process the final JSON format. For example, MusicJSONConverter: used to process the final JSON format (for example, extracting three measures from the final JSON format for testing or creating the extracted measures as music scores of different scenes as needed). NoteLbl: used to display and test the music score attribute elements in the OpenGL environment. CorePlayer: playing the timeline structure of the final JSON format in the form of events according to a custom time movement scheme.

[0081] As shown in Figure 2 , Figure 3 , Figure 2 is a music score displayed after span block division provided by an embodiment of the present application; Figure 3 is a music score displayed after time point block division provided by an embodiment of the present application. For example, in Figure 2 , the music score basic data is displayed equidistantly; in Figure 3 , the music score basic data is independently split and displayed. Meanwhile, Figure 3 , the color and display style of the music score basic data are displayed with special effects.
