[0001] This invention belongs to the field of computer application technology, and in particular relates to a method, device, electronic device and storage medium for marking musical scores. Background Technology

[0002] To facilitate online previewing of sheet music, traditional paper sheet music needs to be converted into electronic sheet music. Currently, the main approach is to convert paper sheet music into image format. This allows searching for sheet music by name, but if only partial sheet music is available without knowing the name, it's impossible to find the corresponding sheet music for that portion. If the partial sheet music is in image format, image search can be used to find the corresponding sheet music. However, image search only finds sheet music with the same layout as the provided portion; if the database used for searching contains sheet music with a different layout, it also fails to retrieve the original sheet music, making the search for sheet music quite cumbersome.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0031] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] With the advancement of technology, more and more technologies are being applied to the music field, and online music teaching has become a trend. Traditional paper-based sheet music has been converted into online sheet music through scanning, making it convenient for people to preview online. While online sheet music previewing is convenient, it also brings another problem: how to find the sheet music you need from the vast amount of online sheet music. Currently, searching for sheet music by name is not possible when you don't know the name, and image search cannot find the same sheet music with different layouts, leading to missed sheet music. All of these situations make finding sheet music very troublesome.

[0033] To solve the above problem, see Figure 1 The present invention provides an embodiment of a method for marking musical scores on a five-line staff, the method comprising the following steps S101-S103:

[0034] S101. Perform music score recognition on the staff notation to determine at least one clef group in the staff notation.

[0035] Five-line musical notation, also known as staff notation, is a musical notation system that consists of five parallel lines. Generally, a single page of five-line musical notation contains multiple clefs, and a piece of music may comprise multiple pages of five-line musical notation.

[0036] S102. For each specified musical element in each staff group, mark it with preset characters according to its order in the staff group to obtain the corresponding staff group string.

[0037] Specifying musical notation elements can include clefs, notes, etc. Different musical notation elements have different meanings. For example, clefs represent pitch, and notes represent rhythm through their duration.

[0038] In some examples, after marking each specified musical element in a staff group with preset characters, the staff group string can be obtained by arranging each specified musical element in the order from left to right in a set of five lines.

[0039] S103. Combine the string strings corresponding to each staff group according to the order of each staff group to obtain the marker string of the staff score.

[0040] In some examples, each character in the staff string can be used as an array element to construct a first array in the order of the characters, representing the staff in array form; the first array representing the staff can be used as an array element to construct a second array in the order of the staffs, representing the sheet music in array form, thus obtaining the label string of the sheet music.

[0041] The staff notation marking method provided in this invention identifies at least one staff group in the staff notation, marks each specified musical element in the staff group according to the order of the specified musical elements in the staff group using preset characters, obtains the corresponding staff group string, and combines the corresponding staff group strings according to the order of the staff groups to obtain the staff notation marking string. In this way, the staff notation can be searched by searching the string, which is convenient for finding and obtaining the staff notation.

[0042] Optionally, in one embodiment of the present invention, step S101, which involves identifying the musical score and determining at least one musical staff group in the musical score, may include: identifying the musical score in an image containing the musical score and determining at least one musical staff group in the musical score.

[0043] In another embodiment of the present invention, step S101, which involves identifying the musical score and determining at least one musical staff group in the musical score, may further include: identifying the musical score in text format, such as Word format musical score, PDF format musical score, etc., and determining at least one musical staff group in the musical score.

[0044] In some examples, target detection in computer vision technology can be used to identify and locate (determine the position of a specified musical element in the staff notation) a specified musical element in a staff notation in the form of an image or text, thereby performing music notation recognition and identifying at least one clef group in the staff notation.

[0045] See Figure 2 Optionally, in one embodiment of the present invention, step S101 of identifying the musical score and determining at least one staff group in the musical score may further include: identifying the musical score and taking a line of musical score composed of multiple measures as a staff group in the musical score.

[0046] In musical notation, bar lines are vertical lines perpendicular to the five parallel lines mentioned earlier. A measure is the area on the five-line staff between adjacent bar lines, and multiple measures can be included in a single line of five lines. Measures are used to determine the rhythm and structure of musical notation.

[0047] In some examples, a staff line may include two rows of lines, one above the other, which can be used for the left and right hands respectively. For instance, in piano sheet music, a staff line consists of two rows of lines. In this case, a measure includes two sets of lines. Arranging the measures according to the order of the lines from left to right yields a set of staves in the sheet music.

[0048] After identifying at least one staff group in the staff score in step S101, in step S102, preset characters can be used to mark each specified musical element in each staff group. Specifically, in one embodiment of the present invention, marking each specified musical element in each staff group with preset characters according to its order in the staff group to obtain the corresponding staff group string includes: determining each staff in each staff group; marking each specified musical element in each staff with preset characters according to its order in the staff to obtain the corresponding staff string; and combining the staff strings according to the order of the staffs to obtain the staff group string.

[0049] In some examples, the staff refers to a set of lines within a measure. After marking each specified musical element in the staff with preset characters, the preset characters corresponding to each specified musical element can be combined according to the left-to-right order of the specified musical elements on the lines to obtain the corresponding staff string. During the combination process, if at least two musical elements overlap in the left-to-right direction on the lines, then the combination is based on the top-to-bottom order of those at least two musical elements on the lines.

[0050] As mentioned earlier, in some examples, a spectral group may include two rows of five lines, one above the other. In this case, a measure includes two sets of five lines, meaning a measure contains two spectral groups. Since a spectral group consists of multiple measures, the individual spectral strings can be combined into a measure string according to the order of their corresponding spectral lines from top to bottom within the measure. Then, the measure strings can be combined according to the order of their corresponding measures from left to right within the five lines to obtain the spectral group string.

[0051] In some examples, the characters in the staff string can be used as array elements to construct a first array according to the order of the characters, representing the staff in array form; the first arrays of each staff in a staff group can be arranged according to their order in the staff group, representing the staff group in array form; or the characters in a staff group can be used as array elements, that is, using the first array of the staff as array elements, constructing a second array according to the order of the staff groups, representing the sheet music in array form. If a staff has no specified musical elements, it can be represented by an empty array.

[0052] For example, Figure 2 The spectral table set shown can be represented as

[0053] ["G","d9","d8"],

[0054] ["F"],

[0055] ["d9","m2","m4","m6","d9","d8"],

[0056] ["u9","m7"],

[0057] ["d9","m2","m4","m6","m5","m4"],

[0058] ["u9","m7"]

[0059] Furthermore, in order to determine each spectral in each spectral group, in one embodiment of the present invention, the staff notation method further includes: determining each measure in each spectral group; and determining a set of five lines in each measure as a spectral.

[0060] As mentioned above, a bar refers to the five-line area between adjacent bar lines. Therefore, the bars in a spectral group can be identified by recognizing adjacent bar lines in each spectral group.

[0061] After determining the measures in the staff, a staff can be determined by identifying the positions of specific musical elements in the measures on the fifth line, such as clefs and notes.

[0062] Furthermore, after determining each measure in each staff group, in order to represent each staff with a preset string, in one embodiment of the present invention, the step of marking each specified musical element in each staff with preset characters according to its order in the staff to obtain the corresponding staff string includes: determining the clef in the first staff and marking the clef with preset characters; determining each note in the first staff and marking each note in the first staff with preset characters based on the relative position of the notehead 3 of each note in the first staff; arranging the marks corresponding to the clef and the marks corresponding to each note in the first staff according to the order of the clef and the notes in the first staff to obtain the first staff string corresponding to the first staff.

[0063] The clef is an element of musical notation, usually located at the beginning of a set of five lines, used to indicate pitch. Clefs include the treble clef, bass clef, and alto clef; their specific symbol images can be found in [link to image]. Figures 4 to 6 In some examples, the preset character "G" can be used to mark high-pitched characters, the preset character "F" can be used to mark low-pitched characters, and the preset character "C" can be used to mark mid-pitched characters.

[0064] Notes are also an element of musical notation. They are typically classified according to their duration, such as whole notes, half notes, quarter notes, etc. (See also...) Figure 2 The notehead 3, also known as the stem, is generally the black ellipse on the note.

[0065] In sheet music, the area above the five parallel lines is the high-pitched range, the area below the five parallel lines is the low-pitched range, and the area between the five parallel lines is the middle-pitched range. (See also...) Figure 3 In some examples, similar to the middle register, when marking the staff notation, the high and low registers can be divided separately using five parallel lines. After the register division is completed, the preset characters uu, u0, u1, u2, u3, u4, u5, u6, u7, u8, u9 can be used to represent the empty space (the area between the two parallel lines) and the parallel lines in the high register, one by one from top to bottom. The preset characters m8, m7, m6, m5, m4, m3, m2, m1, m0 can be used to represent the parallel lines and empty space in the middle register, one by one from top to bottom. The preset characters d9, d8, d7, d6, d5, d4, d3, d2, d1, d0, dd can be used to represent the empty space and the parallel lines in the middle register, one by one from top to bottom.

[0066] Musical elements can be distributed along the five parallel lines of a staff, in the areas between the parallel lines, above the top line, or below the bottom line. See also... Figure 3 In some examples, the positions of musical elements distributed in the staff may include position 1 on a parallel line and position 2 in a space.

[0067] After determining the preset characters corresponding to each position in the staff notation, each clef and note in the first staff can be marked with the preset characters based on their position in the staff. For example, the notehead 3 is on the bottom line of the first staff, and this bottom line corresponds to the preset character m0. Therefore, the preset character m0 is used to represent this note. After marking each clef and note with the preset characters, the markings of each clef and note can be combined into the first staff string of the first staff according to the left-to-right order of each clef and note in the first section of the staff.

[0068] After processing the staff notation, the staff notation marking method provided in this embodiment of the invention can retrieve the same notation in different layouts based on the staff notation marking string.

[0069] See Figure 7 The staff notation method provided in this embodiment of the invention is used to... Figure 7 Marking will yield results Figure 7 The symbol string for the sheet music shown is:

[0070]

[0071]

[0072] See Figure 8 The staff notation method provided in this embodiment of the invention is used to... Figure 8 Marking will yield results Figure 8 The symbol string for the sheet music shown is:

[0073]

[0074]

[0075] See Figure 7 and Figure 8 It can be determined that Figure 7 The sheet music shown is... Figure 8 The sheet music shown is the same piece with different layouts. By comparing the above... Figure 7 The symbol string of the sheet music shown is... Figure 8 The symbol strings of the musical score shown can be used to determine if the clef is removed from either of the two symbol strings. Figure 7 The symbol string of the sheet music shown is... Figure 8The musical scores shown in the figure have the same tag strings. Therefore, when searching for musical scores, by first removing the clef tags from the scores and then performing a match, it is possible to find identical scores with different layouts. Compared to image-based search, which can only find scores with the same layout, the musical score tagging method provided in this embodiment of the invention allows for the search of identical scores with different layouts after tagging. Furthermore, because it uses preset characters for tagging, it has strong anti-interference capabilities and can avoid missing scores, thus facilitating the retrieval of musical scores.
