Description

Technical Field

[0001] This application relates to the field of computer technology, and in particular to a chord learning method, device, storage medium, and program product. Background Technology

[0002] With the development of internet technology and music education, the limitations of traditional offline instrument learning due to venue and teacher resources have become increasingly prominent, while the demand for online instrument learning continues to grow. One of the key focuses of instrument learning is chord learning.

[0003] In related technologies, online chord learning typically relies on audio recognition technology. This involves extracting the audio features of a user's performance, comparing these features with standard audio, and then outputting a score based on the user's performance. Additionally, some online chord learning platforms can also recognize the user's hand movements while playing and provide a score accordingly.

[0004] However, relying solely on audio recognition technology or detecting the user's hand movements while playing a piece results in low learning efficiency for chord learning. Summary of the Invention

[0019] Figure 1 A schematic diagram of an implementation environment provided by an embodiment of this application is shown. This implementation environment can be implemented as an application system. Figure 1 As shown, the implementation environment of this solution may include: terminal device 10 and server 20.

[0020] In some embodiments, the terminal device 10 may be an electronic device such as a mobile phone, tablet computer, personal computer (PC), wearable device, virtual reality (VR) device, augmented reality (AR) device, or in-vehicle device; this application does not limit the scope of the application. The terminal device 10 may run a client of a target application (such as a chord learning application). Optionally, the target application may be an application that requires downloading and installation, or it may be a webpage or an app; this application does not limit the scope of the application.

[0021] In some embodiments, the target application is a chord learning application, which has functions such as displaying sheet music, recording audio information, playing chords, and displaying chord styles.

[0022] Server 20 is used to provide background services for clients of the target application running on terminal device 10. For example, server 20 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDN), and big data and artificial intelligence platforms, but is not limited to these.

For example, the computer device could be... Figure 1 Terminal device 10 in the middle can also be Figure 1 The server 20 in the middle can also be another device other than the terminal device 10 and the server 20.

[0026] Based on the problems existing in related technologies, the technical solutions provided in the embodiments of this application are as follows: Figure 2 As shown. Terminal device 10 displays an interactive interface, which shows a first track. Terminal device 10 collects audio information of a first user playing the first track, calculates a first multi-dimensional score based on the first user's performance, updates the user profile of the first user based on the first multi-dimensional score, and then generates recommended content for the first user based on the updated user profile.

[0027] Optionally, the calculation of multidimensional rating information, updating user profiles, and generating recommended content can also be performed by the server 20.

[0028] Please refer to Figure 3 The diagram illustrates a flowchart of a chord learning method provided in one embodiment of this application. The execution entity for each step of the method can be a computer device; for example, the computer device could be... Figure 1 The illustrated implementation environment includes a terminal device 10 (e.g., each step is performed by a client of the target application running on the terminal device 10) or a server 20. The method may include at least one of steps 310-340 below.

[0029] Step 310: Obtain the first multi-dimensional score information generated for the first user's performance of the first piece of music. The first multi-dimensional score information includes the identifier of the first piece of music and the score values ​​of multiple dimensions.

[0030] In some embodiments, the first user refers to a user learning chords. Alternatively, the first user refers to an entity that registers and uses the target application to engage in chord learning.

[0031] In some embodiments, the track is a musical resource in the target application for users to learn chords. Optionally, the first track is one of the tracks provided in the target application. Optionally, the first track includes one or more of the following: one or more chords; one or more chord pairs; one or more chord progressions. Typically, a chord pair includes two to three chords, and a chord progression includes four to five chords.

[0032] In some embodiments, the first multidimensional scoring information is scoring information generated for a first user's performance of a first piece of music. Optionally, when the execution entity of each step of the method is a terminal device, the terminal device collects audio information generated by the first user's performance of the first piece of music and generates the first multidimensional scoring information based on the audio information generated by the first user's performance of the first piece of music. Optionally, the first multidimensional scoring information includes an identifier of the first piece of music and scoring values ​​of multiple dimensions. The identifier of the first piece of music is used to uniquely identify the piece; the scoring values ​​of multiple dimensions refer to the numerical values ​​obtained by scoring the first user's performance of the first piece of music from different perspectives.

[0033] In some embodiments, audio information of a first user playing a first piece of music is collected, and the audio information is compared with the sheet music corresponding to the first piece of music through an audio comparison algorithm to obtain first multidimensional score information.

[0034] The first multi-dimensional scoring information includes multiple dimensions of scoring values ​​generated for the first user's performance of the first piece. Compared to scoring the first user's performance of the first piece from a single dimension, the first multi-dimensional scoring information is more able to reflect the first user's actual performance ability.

[0035] Step 320: Based on the first multidimensional scoring information, update the user profile of the first user. The user profile includes a mastery value of at least one chord pair. The chord pair includes a first chord and a second chord. The mastery value of the chord pair is used to characterize the first user's ability to switch from the first chord to the second chord.

[0036] In some embodiments, the user profile is derived based on the user's playing ability, behavioral data, etc. Optionally, the user profile includes one or more of the following: a mastery score for at least one chord; a mastery score for at least one chord pair; and a mastery score for at least one chord progression. The mastery score is a quantified value based on the user's mastery level. Optionally, the chord mastery score refers to the user's mastery of that chord. For example, the user profile includes mastery scores for 12 chords, where 12 chords refer to 12 chords constructed using all 12 semitones of an octave as the root note. Optionally, the chord pair mastery score refers to the user's mastery of that chord pair. For example, the user profile includes 144 chord pairs, each chord pair comprising 2 or 3 chords. Optionally, the chord progression mastery score refers to the user's mastery of that chord. For example, each chord progression comprises 4 or 5 chords.

[0037] In some embodiments, the mastery value of a chord pair is used to characterize the first user's ability to transition from a first chord to a second chord. Optionally, a high mastery value indicates a strong ability of the first user to transition from a first chord to a second chord. Optionally, a low mastery value indicates a weak ability of the first user to transition from a first chord to a second chord. Optionally, the first user's ability to transition from a first chord to a second chord refers to the first user's ability to complete the playing transition from a first chord to a second chord. Optionally, the playing ability to transition from a first chord to a second chord is determined by one or more of the following: the timing of the transition; the intonation of the first chord; the intonation of the second chord, etc.

[0038] In some embodiments, based on the first multidimensional scoring information, the user's mastery of the chord pairs included in the first piece is determined, and based on the user's mastery of the chord pairs included in the first piece, the mastery values ​​of the corresponding chord pairs in the user profile are updated. For example, the first piece includes a first chord pair and a second chord pair, the user profile includes mastery values ​​of the first chord pair, the second chord pair, and the third chord pair, and the mastery values ​​of the first chord pair, the second chord pair, and the third chord pair in the user image are all 0. The first multidimensional scoring information generated by the first user playing the first piece is obtained, and based on the first multidimensional scoring information, the user's mastery value for the first chord pair is determined to be 0.8, and the mastery value for the second chord pair is determined to be 0.7. Based on the first multidimensional scoring information, the user profile of the first user is updated, and the updated user profile includes a mastery value of 0.8 for the first chord pair and a mastery value of 0.7 for the second chord pair.

[0039] Based on the first multidimensional scoring information, the user profile of the first user is dynamically updated, which can objectively reflect the user's mastery of at least one chord pair.

[0040] Step 330: Based on the user profile, generate recommended content for the first user, including a second piece of music associated with the first user's chord pairs to be improved.

[0041] In some embodiments, the chord pairs to be improved refer to the chord pairs with the lowest mastery scores of the first user. Optionally, when the number of chord pairs to be improved is one, the chord pairs to be improved are the chord pairs with the lowest mastery scores of the first user. For example, the user profile of the first user includes mastery scores for a first chord pair, a second chord pair, and a third chord pair, wherein the mastery score for the first chord pair is 0.8, the mastery score for the second chord pair is 0.6, and the mastery score for the third chord pair is 0.55. When the number of chord pairs to be improved is one, the chord pairs to be improved for the first user are the third chord pairs, and the recommended content for the first user includes a second track associated with the third chord pair. Optionally, when the number of chord pairs to be improved is a first number, the mastery scores of at least one chord pair included in the user profile of the first user are sorted, and based on the sorting result, a first number of chord pairs with the lowest mastery scores are determined as the chord pairs to be improved for the first user. For example, the user profile of the first user includes mastery scores for the first chord pair, the second chord pair, and the third chord pair, wherein the mastery score for the first chord pair is 0.8, the mastery score for the second chord pair is 0.6, and the mastery score for the third chord pair is 0.55. When the number of chord pairs to be improved is a first quantity, and the first quantity is 2, the chord pairs to be improved for the first user are the second chord pair and the third chord pair. The recommended content for the first user includes a second track associated with the second chord pair and / or the third chord pair.

[0042] Additionally, it should be understood that the second piece can also be a chord progression associated with the chord pair to be improved.

[0043] In some embodiments, the user profile includes a mastery score of at least one chord progression, wherein the chord progression includes at least two chords, and the mastery score characterizes the first user's mastery of that chord progression. Optionally, based on the user profile, recommended content is generated for the first user, including a third piece of music associated with the first user's chord progressions for improvement.

[0044] Here, "chord progressions to be improved" refers to chord progressions with low mastery scores for the first user. Optionally, when the number of chord progressions to be improved is one, it is the chord progression with the lowest mastery score for the first user. For example, the first user's profile includes mastery scores for a first chord progression, a second chord progression, and a third chord progression, where the mastery score for the first chord progression is 0.8, the mastery score for the second chord progression is 0.6, and the mastery score for the third chord progression is 0.55. When the number of chord progressions to be improved is one, the first user's chord progression to be improved is the third chord progression, and the recommended content for the first user includes a third track associated with the first chord progression. Optionally, when the number of chord progressions to be improved is a second number, the mastery scores of at least one chord progression included in the first user's profile are sorted, and based on the sorting result, the second number of chord progressions with the lowest mastery scores are determined as the first user's chord progressions to be improved. For example, the user profile of the first user includes mastery scores for the first chord progression, the second chord progression, and the third chord progression, wherein the mastery score for the first chord progression is 0.8, the mastery score for the second chord progression is 0.6, and the mastery score for the third chord progression is 0.55. When the number of chord progressions to be improved is a second number, and the second number is 2, the chord progressions to be improved for the first user are the second chord progression and the third chord progression. The recommended content for the first user includes a third track associated with the second chord progression and / or the third chord progression.

[0045] The recommended content for the first user is determined by the user profile of the first user, and the recommended content includes a second piece of music related to the chords that the first user needs to improve, so that the first user can learn the chords that need to be improved in a targeted manner based on the recommended content.

[0046] Step 340: Obtain the second multi-dimensional score information generated for the first user's performance of the second piece, and update the user profile again based on the second multi-dimensional score information. The second multi-dimensional score information includes the identifier of the second piece and score values ​​of multiple dimensions.

[0047] In some embodiments, the second track includes a chord pair to be improved by the first user. Optionally, the second track also includes one or more of the following: one or more chords; one or more chord pairs; one or more chord progressions.

[0048] In some embodiments, the second multidimensional scoring information is scoring information generated for the first user's performance of the second piece. Optionally, when the execution entity of each step of the method is a terminal device, the terminal device collects audio information generated by the first user's performance of the second piece and generates the second multidimensional scoring information based on the audio information generated by the first user's performance of the second piece. Optionally, the second multidimensional scoring information includes an identifier of the second piece and multiple dimensions of scoring values. The identifier of the second piece is used to uniquely distinguish the piece; the multiple dimensions of scoring values ​​refer to the numerical values ​​obtained by scoring the first user's performance of the second piece from different perspectives.

[0049] In some embodiments, audio information of a first user playing a second piece of music is collected, and the audio information is compared with the sheet music corresponding to the second piece of music through an audio comparison algorithm to obtain second multi-dimensional scoring information.

[0050] In some embodiments, after updating the user profile again based on the second multidimensional rating information, the process returns to step 330 above to continue generating recommended content for the first user.

[0051] By acquiring second-dimensional rating information and updating the user profile based on it, we can not only further improve the matching degree between the user profile and the first user, but also form a complete learning loop and improve the adaptability between the chord learning method and the user.

[0052] The technical solution provided in this application update the user profile of the first user by obtaining the first multi-dimensional score information generated by the first user playing the first piece of music, and generates recommended content for the first user based on the user profile including the mastery value of at least one chord pair. When the first user plays the second piece of music in the recommended content, the second multi-dimensional score information generated by the first user playing the second piece of music is obtained to update the user profile of the first user again. This improves the accuracy of the recommended content and allows users to practice the pieces they are not good at, thereby helping to improve the user's learning efficiency of chord playing on the instrument.

[0053] Please refer to Figure 4 The diagram illustrates a flowchart of a chord learning method provided in another embodiment of this application. The execution entity for each step of this method can be a computer device; for example, the computer device could be... Figure 1 The illustrated implementation environment includes a terminal device 10 (e.g., each step is performed by a client of the target application running on the terminal device 10). The method may include at least one of the following steps 410 to 460.

[0054] Step 410: Obtain the first multi-dimensional score information generated for the first user's performance of the first piece of music. The first multi-dimensional score information includes the identifier of the first piece of music and score values ​​in multiple dimensions.

[0055] For details not described in step 410 above, please refer to the description of step 310 in the above embodiments.

[0056] Step 420: Obtain the score values ​​of multiple dimensions and the weight values ​​of multiple dimensions included in the first dimension score information.

[0057] In some embodiments, the multiple dimensions include one or more of the following: Dimension (1): Switching speed, used to indicate the degree of match between the time required for the first user to switch from one chord to the next when playing the first piece and the standard time.

[0058] Dimension (2): Rhythmic accuracy, used to indicate the degree of synchronization between the audio beats played by the first user and the musical beats of the first track.

[0059] Dimension (3): Consistency, used to indicate the degree of matching between the chords played by the first user and the chords in the score information of the first piece.

[0060] Dimension (4): Pitch accuracy, used to indicate the degree of difference between the frequency of notes in the audio information played by the first user and the standard pitch.

[0061] Dimension (5): Completeness, which indicates the degree of completeness of the audio information played by the first user relative to the sheet music information of the first track.

[0062] Regarding dimension (1) above, in some embodiments, when the first piece is a song, the switching speed score generated by the first user playing the first piece is determined by calculating the degree of matching between the time required for the first user to switch from the first phrase to the next phrase and the standard time. In some cases, each phrase corresponds to a chord progression; therefore, when the first piece is a song, the switching speed score generated by the first user playing the first piece is determined by calculating the degree of matching between the time required for the first user to switch from the first chord progression to the next chord progression and the standard time.

[0063] Regarding dimension (2) above, in some embodiments, a score for the rhythmic accuracy of the first user's performance of the first piece is determined by calculating the difference between the number of beats per minute of the first user playing the first piece and the number of beats per minute of the first piece. Here, the number of beats per minute refers to the number of beats within one minute, used to indicate the playing speed. Optionally, the higher the rhythmic accuracy, the higher the degree of synchronization between the audio beats played by the first user and the musical beats of the first piece. Optionally, the lower the rhythmic accuracy, the lower the degree of synchronization between the audio beats played by the first user and the musical beats of the first piece.

[0064] Regarding dimension (3) above, in some embodiments, the consistency score generated by the first user's performance of the first piece is determined by calculating the degree of pitch matching between the chords played by the first user and the chords in the score information of the first piece. Optionally, consistency is used to indicate whether the first user has made any wrong notes or missed notes when playing the first piece. For example, if the chords in the score information of the first piece are the first pitch, the second pitch, and the third pitch, and the chords played by the first user are the first pitch and the second pitch, then there is a missed note when the first user plays the chords of the first piece, and the consistency score generated by the first user's performance of the first piece is low.

[0065] Regarding the aforementioned dimension (4), in some embodiments, the pitch accuracy score generated by the first user playing the first piece is determined by calculating the degree of difference between the note frequencies in the audio information played by the first user and the standard pitch.

[0066] Regarding the aforementioned dimension (5), in some embodiments, the completion score of the first user's performance of the first piece is determined by calculating the completeness of the audio information played by the first user compared to the sheet music information of the first piece. For example, the sheet music information of the first piece includes four chord progressions, while the audio information played by the first user only includes two chord progressions. Therefore, the completion score of the first user's performance of the first piece is 0.5.

[0067] Step 430: Based on the rating values ​​of multiple dimensions and the weight values ​​of multiple dimensions, determine the increment of the first user's mastery of chord pairs.

[0068] In some embodiments, the weight value of a dimension refers to the degree of influence that dimension has on the increment of mastery of chord pairs. Optionally, the larger the weight value of a dimension, the greater its influence on the increment of mastery of chord pairs. Optionally, the smaller the weight value of a dimension, the smaller its influence on the increment of mastery of chord pairs.

[0069] In some embodiments, the incremental mastery of a chord pair by a first user is determined by the following three dimensions and their weights: switching speed, rhythmic accuracy, and consistency. For example, if the switching speed score is 0.8 and its weight is 0.6; the rhythmic accuracy score is 0.7 and its weight is 0.3; and the consistency score is 0.8 and the switching speed weight is 0.1, then the incremental mastery of the chord pair by the first user is 0.6. 0.8 + 0.3 0.7 + 0.1 0.8 = 0.77.

[0070] Step 440: Based on the mastery increment, update the mastery values ​​of the chord pairs included in the user profile of the first user.

[0071] In some embodiments, the mastery value of the chord pair included in the user profile of the first user is replaced with the mastery increment of the chord pair. For example, if the user profile of the first user includes a mastery value of the first chord pair, and the mastery value is 0.6, and the mastery increment of the first user for the first chord pair is 0.77, then the mastery value of the first chord pair included in the user profile of the first user is updated to 0.77.

[0072] Step 450: Based on the user profile, generate recommended content for the first user, including a second piece of music associated with the first user's chord pairs to be improved.

[0073] Step 460: Obtain the second multi-dimensional score information generated for the first user's performance of the second piece, and update the user profile again based on the second multi-dimensional score information. The second multi-dimensional score information includes the identifier of the second piece and score values ​​of multiple dimensions.

[0074] For details not provided in steps 450 and 460 above, please refer to the descriptions of steps 330 and 340 in the above embodiments.

[0075] In some embodiments, the method further includes steps 470-480 (not shown in the figures).

[0076] Step 470: Periodically or based on a triggered event, detect the deviation between the mastery score of any chord pair in the user profile and the actual mastery score determined based on recent multidimensional scoring information.

[0077] In some embodiments, at first preset time intervals, the deviation between the mastery score of any chord pair in the user profile and the actual mastery score determined based on recent multidimensional scoring information is detected. Optionally, the first preset time interval is determined by relevant personnel.

[0078] In some embodiments, the triggering event is triggered by a first user. Optionally, in response to the triggering event triggered by the first user, the deviation between the mastery score of any chord pair in the user profile and the actual mastery score determined based on recent multidimensional rating information is detected.

[0079] In some embodiments, the deviation between the mastery score of the second chord pair in the user profile and the actual mastery score determined based on recent multidimensional rating information is detected, wherein the mastery score of the second chord pair in the user profile is predicted by the user profile. For example, if the first user has not practiced the second chord pair, the user profile corresponding to the first user predicts a mastery score of 0.8 for the first user regarding the second chord pair based on the first user's behavioral data. After the first user plays a first piece including the second chord pair, the mastery score of the first user regarding the second chord pair is obtained as 0.6, meaning the deviation between the mastery score of the second chord pair in the user profile and the actual mastery score determined based on recent multidimensional rating information is 0.2.

[0080] Step 480: If the deviation is greater than the second preset threshold, adjust the mastery value of the chord pair and reduce the confidence level corresponding to the mastery value of the chord pair.

[0081] In some embodiments, if the deviation between the mastery value of any chord pair in the user profile and the actual mastery value determined based on recent multidimensional rating information is greater than a second preset threshold, the mastery value of the chord pair is adjusted and the confidence level corresponding to the mastery value of the chord pair is reduced.

[0082] Specifically, if the deviation between the mastery score of any chord pair in the user profile and the actual mastery score determined based on recent multidimensional rating information exceeds a second preset threshold, it typically indicates that the user profile cannot accurately reflect the user's recent mastery of that chord pair. Therefore, it is necessary to adjust the mastery score of that chord pair in the user profile and reduce the confidence level corresponding to the mastery score. For example, if the second preset threshold is 0.15, and the mastery score of the second chord pair in the first user's user profile is 0.5, in response to a trigger event, if the actual mastery score determined by the first user's recent multidimensional rating information is detected to be 0.7, meaning the deviation between the mastery score of the second chord pair in the user profile and the actual mastery score determined by the first user's recent multidimensional rating information exceeds the second preset threshold, the mastery score of the second chord pair in the user profile is adjusted to 0.7, and the confidence level corresponding to the mastery score of the second chord pair is reduced.

[0083] Optionally, the second preset threshold is determined by relevant personnel. Optionally, if the deviation is greater than the second preset threshold, the mastery value of the chord pair is adjusted to the actual mastery value determined based on recent multidimensional scoring information. Optionally, the confidence level corresponding to the mastery value is used to indicate the reliability of the mastery value of the chord pair in the user profile. For example, if multidimensional scoring information from five instances of the first user playing the first chord pair and one instance of the first user playing the second chord pair are obtained within the last three days, and the user profile of the first user is updated based on the multidimensional scoring information, then in the user profile of the first user, the confidence level corresponding to the mastery value of the first chord pair is higher than the confidence level corresponding to the mastery value of the second chord pair.

[0084] By detecting the deviation between the mastery score of any chord pair in the user profile and the actual mastery score determined based on recent multidimensional scoring information, and adjusting the mastery score of the chord pair and reducing the confidence level corresponding to the mastery score of the chord pair when the deviation is large, the matching degree between the mastery score of the chord pair included in the user profile and the user's recent chord playing ability can be improved.

[0085] The technical solution provided in this application determines the increment of a first user's mastery of chord pairs based on multiple factors, including switching speed, rhythm accuracy, consistency, pitch accuracy, and completion. Based on the increment of mastery, the user profile of the first user is updated, which makes the updated user profile more consistent with the current mastery of chord pairs of the first user.

[0086] Please refer to Figure 5 The diagram illustrates a flowchart of a chord learning method provided in another embodiment of this application. The execution entity for each step of this method can be a computer device; for example, the computer device could be... Figure 1 The illustrated implementation environment includes a terminal device 10 (e.g., each step is performed by a client of the target application running on the terminal device 10) or a server 20. The method may include at least one of steps 510 to 570 below.

[0087] Step 510: Obtain the sheet music information for the first piece.

[0088] In some embodiments, the sheet music information refers to the standard musical content corresponding to the track, serving as a reference benchmark for multi-dimensional scoring information. Optionally, the sheet music information includes one or more of the following: track identifier, section information, lyrics, rhythm, etc. The track identifier is used to uniquely distinguish different track numbers; the section information is used to divide the first track into segments according to its musical structure; the lyrics refer to the text corresponding to the song; and the rhythm is used to divide the events of the first track. Optionally, the sheet music information is a rendered sheet music, displayed as a PDF (Portable Document Format), image, or JSON (JavaScript Object Notation).

[0089] Step 520: Perform structured parsing on the musical score information to obtain a structured tag set, which includes a set of single chords, a sequence of chord pairs, chord identifiers, and key signatures.

[0090] In some embodiments, structured parsing of musical score information refers to converting the musical score information into a data structure that the system can read. Optionally, the structured tag set includes: a set of single chords, a sequence of chord pairs, chord progression identifiers, and a key signature. The set of single chords refers to the set of all, deduplicated, individual chords used in the musical score information; the sequence of chord pairs refers to a sequence of chord pairs arranged in measure order, where each chord pair consists of a transition from a starting chord to a target chord; the chord progression identifier uniquely identifies a chord progression in the score; and the key signature indicates the key on which the score is based.

[0091] Optionally, the chord sequence refers to the key chord sequence converted into a scale within the key. Scale conversion within the key refers to converting a specific chord within the key into a numerical scale within that key; the key chord sequence can be a sequence of chord pairs that appear frequently in the musical score.

[0092] Step 530: Obtain the first multi-dimensional score information generated for the first user's performance of the first piece of music. The first multi-dimensional score information includes the identifier of the first piece of music and the score values ​​of multiple dimensions.

[0093] Step 540: Based on the first multidimensional scoring information, update the user profile of the first user. The user profile includes a mastery value of at least one chord pair. The chord pair includes a first chord and a second chord. The mastery value of the chord pair is used to characterize the first user's ability to switch from the first chord to the second chord.

[0094] For details not described in steps 530 and 540 above, please refer to the description of steps 310 and 320 in the above embodiments.

[0095] Step 550: Obtain chord pairs in the user profile whose mastery value is less than the first preset threshold, and use them as the chord pairs to be improved for the first user.

[0096] In some embodiments, chord pairs in a user profile with a mastery score less than a first preset threshold refer to chord pairs where the first user has a poor mastery score. Optionally, the first preset threshold is set by relevant personnel.

[0097] Step 560: Based on the chord pairs to be improved, select a piece from the preset music library that contains the chord pairs to be improved and / or related chord progressions of the chord pairs to be improved, as the second piece.

[0098] In some embodiments, based on the structured tag set corresponding to tracks in a preset music library, a track containing the chord pair to be improved and / or the associated chord progression of the chord pair to be improved is determined as the second track. Optionally, the associated chord progression of the chord pair to be improved refers to containing the associated progression of the chord pair to be improved. Optionally, the preset music library is provided by the target application.

[0099] Step 570: Obtain the second multi-dimensional score information generated for the first user's performance of the second piece, and update the user profile again based on the second multi-dimensional score information. The second multi-dimensional score information includes the identifier of the second piece and the score values ​​of multiple dimensions.

[0100] For details not described in step 570 above, please refer to the description of step 340 in the above embodiments.

[0101] In some embodiments, the method further includes the following steps 580-590 (not shown in the figures).

[0102] Step 580: Based on the first user's historical behavior data, determine the first user's preferred music tracks.

[0103] In some embodiments, the historical behavior data of the first user refers to the accumulated interaction records between the first user and the terminal device. Optionally, the historical behavior data of the first user includes: the first user's dwell time on a track, click rate, and track browsing history. Wherein, the first user's dwell time on a track refers to the duration the user spends on the interface corresponding to the track; the click rate refers to the number of times the first user clicks on the track; and the track browsing history refers to the tracks the first user has browsed.

[0104] In some embodiments, different weight values ​​are set for different behaviors of the first user. Based on the first user's historical behavior data and the weight values ​​corresponding to different behaviors, the first user's preferences are determined, thereby determining the first user's preferred tracks.

[0105] Step 590: Generate recommended content including preferred tracks.

[0106] In some embodiments, recommended content is generated for a first user, including preferred tracks. Optionally, if the first user has few chords to improve, the first user's preferred tracks are determined based on the first user's historical behavior data, and recommended content including the preferred tracks is generated.

[0107] The technical solution provided in this application embodiment improves the speed and accuracy of obtaining structured tag sets by performing structured parsing of the score information of the first track, compared with manually annotating track information.

[0108] For example, the terminal device receives first multi-dimensional scoring information generated by a first user playing a first piece of music during chord learning. This first multi-dimensional scoring information includes one or more of the following: score values ​​across five dimensions, millisecond-level chord switching timing data, error sub-type labels, and a comprehensive score. Optionally, the five dimensions are: switching speed, rhythmic accuracy, consistency, pitch accuracy, and completion. Optionally, the millisecond-level chord switching timing data refers to recording the chord switching moments during the first user's performance of the first piece with millisecond precision. Optionally, the error sub-type labels indicate the types of problems encountered by the first user during their performance of the first piece. For example, error sub-types include: chord errors, chord switching delays, rhythmic errors, etc. Optionally, the comprehensive score refers to the overall evaluation of the first user's performance of the first piece.

[0109] Based on the first multi-dimensional scoring information, the terminal device calculates the user profile of the first user, which includes three parts. The user profile includes the following three parts: mastery score of single chords, mastery score of chord pairs, and mastery score of chord progressions; wherein the mastery score of chord pairs includes the scores of 144 chord pairs.

[0110] The terminal device parses the first track, as well as the recommended content including the second track and / or preferred tracks, into a structured tag set. The structured tag set includes: a set of single chords, a sequence of chord pairs, and chord identification; wherein the sequence of chord pairs is a key chord pair sequence in key scale.

[0111] Based on user profiles and structured tag sets of music tracks, matching is performed at three levels: chords, chord pairs, and chord progressions. Recommended content is generated for the first user, including a second track and explanatory text explaining why it is recommended. It should be understood that the second track can be a track containing the first user's chord pairs to be improved and / or related chord progressions of those pairs, or a track containing the first user's chord progressions to be improved.

[0112] Obtain the second multi-dimensional rating information generated by the first user's performance of the second piece. The second multi-dimensional rating information includes the identifier of the second piece and rating values ​​of multiple dimensions. Based on the second multi-dimensional rating information, update the user profile of the first user again.

[0113] In addition, for the user profile of the first user, the deviation between the mastery score of any chord pair in the user profile and the actual mastery score determined based on recent multidimensional scoring information is periodically detected; if the deviation exceeds a second preset threshold, the mastery score of that chord pair is adjusted and the confidence level corresponding to the mastery score of that chord pair is reduced. In some cases, the mastery score of the chord pair in the user profile is predicted based on the first user's playing ability.

[0114] Please refer to Figure 6 The diagram illustrates a flowchart of a chord learning method provided in another embodiment of this application.

[0122] Step 630: Display recommended content for the first user. The recommended content includes a second track associated with the first user's chord pairs to be improved. The chord pairs to be improved are determined based on the first user's user profile, which includes the first user's mastery score for at least one chord pair. The chord pairs include a first chord and a second chord. The mastery score of the chord pairs is used to characterize the first user's ability to switch from the first chord to the second chord.

[0123] In some embodiments, the method further includes steps 640-650 (not shown in the figures).

[0124] Step 640: Display the information of the first user's chord pairs to be improved in the interactive interface.

[0128] In some embodiments, in response to a first user's first triggering operation on the chord pair to be improved, practice information for the chord pair to be improved is displayed. Based on the practice information, the first user practices the chord pair to be improved to increase the first user's mastery score for the chord pair.

[0129] In some embodiments, the method further includes step 660 (not shown in the figure).

[0130] Step 660: Display the first user's preferred tracks in the interactive interface. The preferred tracks are determined based on the first user's historical behavior data.

[0131] In some embodiments, the user's preferred music tracks are displayed in the interactive interface. Optionally, the displayed music track information includes: the name of the preferred music track, the artist of the preferred music track, and the music score type of the music track. The music score type of the preferred music track includes music scores in at least one key.

In response to a click on the record button, the acquisition of audio information emitted by the first user playing the first track begins. Optionally, in response to the second triggering operation on the record button, the record button switches its display mode to notify the first user that recording has started.

[0138] Step 690: In response to the third trigger operation on the record button, stop collecting audio information emitted by the first user playing the first track; wherein the trigger time of the third trigger operation is after the trigger time of the second trigger operation, and the first multi-dimensional scoring information is determined based on the audio information emitted by the first user playing the first track.

[0145] The chord learning system will now be introduced and explained through an example.

[0146] Please refer to Figure 11 The illustration shows a schematic diagram of a chord learning system provided in one embodiment of this application. The chord learning system includes the acquisition of sheet music information and a user learning path. The acquisition of sheet music information refers to extracting one or more of the following from the sheet music: chords, chord progressions, modal chords, key chords, etc. The user learning path refers to the user learning the chords provided by the chord learning system, the chord learning system scoring the user's performance, updating the user profile based on the scoring results, recommending chords or sheet music to the user based on the updated user profile, the user practicing the recommended chords or sheet music, and then the chord learning system scoring the user's performance again.

[0147] The user profile includes the user's skill set, which includes one or more of the following: mastery level of at least one chord; mastery level of at least one chord pair; mastery level of at least one chord progression; mastery level of chord transitions; mastery level of rhythm; and mastery level of performance fluency. Specifically, mastery level of chord transitions refers to switching speed; mastery level of rhythm refers to rhythmic accuracy; and mastery level of performance fluency refers to consistency.

[0148] In some embodiments, the chord learning system includes one or more of the following modules: a score structuring module; a scoring module; a skills module; and a recommended content update module.

[0149] Optionally, the score structuring module is used to generate score information based on data such as song ID (Identify), lyrics, and beats per minute, and to extract information such as chords, chord progressions, and key chord pairs from it. In some cases, key chord pairs are chord pairs that appear frequently in the track.

[0150] For example, the sheet music information for the first piece is as follows: { "Identifier for the first track (sheet_id)": "s_track name_track artist", Track title: "XX", "Artist": "XXX", "key": "X", "Beats per minute (bpm)": XX, "Duration (duration_sec)": XXX, "chord progression tags": [ {"Chord progression ID": "1-5-6-4", "Number of occurrences": 4, "Sections": ["Verse 1", "Chorus"]} {"Chord ID (progression_id)": "4-5-3-6", "Number of occurrences (occurrences)": 2, "Sections (sections)": ["Bridge"]} ], "chord pair tag (chord_pair_sequence)": [ {"Chord Pair": ["C", "G"], "Position": "Verse 1: bar 2 → bar 3"}, {"Chord Pair": ["G", "Am"], "Position": "Verse 1: bar 3 to bar 4"} {"Chord Pair": ["Am", "F"], "Position": "Verse 1 (bar4→bar5) from bar4 to bar5"} ], "chord set": ["C", "G", "Am", "F", "Dm", "Em"], "Difficulty level": "2", "parsed_at"": "XXX", "parser_version": "XXX" } Among them, "1-5-6-4" and "4-5-3-6" are series; "C", "G", "Am", "F", "Dm", and "Em" refer to key signatures.

[0151] Optionally, the scoring module is used to generate multi-dimensional scoring information for the user's performance of a piece or chord. Optionally, the multi-dimensional scoring information includes scores from multiple dimensions, including one or more of the following: switching speed, rhythmic accuracy, consistency, pitch accuracy, and completion. Optionally, the multiple dimensions include: user performance score.

[0152] For example, the first multidimensional score information output by the scoring module is as follows: { "rhythm_accuracy": 0.88, "pitch_accuracy": 0.95, "switch_speed": 0.72, "consistency": 0.85, "completeness": 0.90}.

[0153] Optionally, a skills module is used to display the user's mastery of chords. For example, the skills module includes: chord mastery, transition mastery, and progression mastery; wherein, chord mastery refers to the user's mastery of a single chord; transition mastery refers to the user's mastery of a chord pair, and in some cases, transition mastery can also be considered as modal mastery; and progression mastery refers to the user's mastery of chord progressions.

[0154] Optionally, a recommended content update module is used to generate recommended content for users.

[0155] For example, the recommended content update module includes the following steps: retrieving historical profiles, obtaining mastery increments, determining chord pairs to be improved, determining chord progressions to be improved, and generating recommended content.

[0156] The pseudocode for retrieving the historical profile is: old = db.get_transition_mastery(user_id, from_c, to_c).

[0157] The formula for calculating the degree increment is Δm = 0.6. Switching speed score +0.3 Rhythm accuracy score + 0.1 The consistency score; where Δm is the mastery increment, 0.6 is the weight value for switching speed, 0.3 is the weight value for rhythm accuracy, and 0.1 is the weight value for consistency. The pseudocode for obtaining the mastery increment is: delta = ( 0.6 score_event['dimension_scores']['switch_speed'] + 0.3 score_event['dimension_scores']['rhythm_accuracy'] + 0.1 score_event['dimension_scores']['consistency']).

[0158] Optionally, the chord pairs to be improved are those with a mastery score greater than 0.5 and less than 0.6 in the user profile. The pseudocode for determining the chord pairs to be improved is: weak_pairs = [ (f, t) for f in CHORDS for t in CHORDS if 0.5<= trans_m[(f, t)].mastery<0.6 ] if weak_pairs: Optionally, if the chord pair to be improved is determined, recommended content is generated for the first user, which includes a second track associated with the chord pair to be improved for the first user. For example, the pseudocode for generating recommended content for the first user is: return build_weak_pair_lesson (weak_pairs[0]).

[0159] Optionally, the chord progression to be improved is a chord progression with a mastery score greater than 0.5 and less than 0.6 in the user profile. The pseudocode for determining the chord progression to be improved is: weak_progs = [ p for p in progressions if 0.5<= prog_m[p].mastery<0.6 ] if weak_progs: return build_progression_lesson(weak_progs[0]) Optionally, if the chord progression to be improved is determined, recommended content is generated for the first user, including a second piece of music associated with the chord progression to be improved for the first user.

[0160] Optionally, the generated recommended content includes: practice pieces for the first user's next stage of chord learning. Here, the next stage of chord learning refers to learning other chords, other chord pairs, or other chords. Optionally, if the first user's mastery level of the first chord pair is greater than a third preset threshold, the generated recommended content for the first user includes: pieces containing a second chord pair, where the second chord pair is different from the first chord pair.

[0161] For example, if the first user's chord mastery score is greater than 0.8, recommended content is generated that includes practice pieces for the first user's next stage of chord learning. The pseudocode for generating the practice pieces for the first user's next stage of chord learning is: `completed = [p for p in progressions if prog_m[p].mastery>= 0.8]` if completed: next_prog = find_adjacent_progression(completed[-1]) return build_progression_lesson(next_prog) Optionally, popular tracks in a preset music library are determined, and recommended content containing these popular tracks is generated. The popular tracks are determined by user behavior data within the platform. For example, the pseudocode for generating recommended content containing popular tracks is: `return build_progression_lesson(popular _progressions[0])`.
