s101, matching a corresponding learning stage according to the self condition of the user, wherein the learning stage comprises corresponding learning content and an evaluation method.
In the present embodiment, the piano performance learning method described in the present embodiment is implemented by providing a piece of smart piano performance learning application software on a smart terminal. The target user downloads the intelligent piano playing learning application software corresponding to the embodiment on the intelligent terminal, and the target user can register and log in the application software. Specifically, in the initial interface, a registration interface is displayed for the target user, the target user is instructed to enter basic information, the basic information entered by the target user is acquired, and the initial piano rating of the target user is judged according to the basic information entered by the target user. The judgment method comprises the steps of covering whether a target user is a piano beginner or a piano learner with certain experience in basic information input by the target user, and grading the initial piano grade of the target user according to the information in the basic information; in addition, or in combination with the method of presenting the initial piano rating evaluation music to the target user for evaluation by the target user, the target user may be subjected to the initial piano rating by the score of the target user in the piece of initial piano rating evaluation music.
And combining the information to match the target user with the initial piano grade of the target user in the learning stage of the application. The learning stage is specifically a learning spectrum training stage, a boosting training stage and a full-song training stage. Besides different learning contents, each learning stage also corresponds to different testing contents and testing methods, and the testing requirements of each stage are also different. It can be understood that the target user for the learning-score training phase is a user with a low proficiency level on the current music score or a user unfamiliar with the current music score with a low initial piano grade or substantially zero, and the target user for the boosting training phase is a target user passing through the learning-score training phase or a target user with a certain mastering familiarity level on the current music score in the initial piano grade; the full-song practice stage generally aims at target users who are completely familiar with and master the current music score and have certain piano bases and can completely play the music score, and the target users have higher scores in the initial piano grade. Of course, the division criteria of the three stages corresponding to the score of the initial piano score may be determined according to data collection in actual applications or according to rule requirements.
Of course, in the above description, the method of matching the corresponding learning stage according to the user's own situation in the method steps of the present embodiment is matched by the initial piano rank matched according to the familiarity degree of the target user with the current music score, but in another embodiment, it may be determined directly according to the user's selection, that is, after the user enters his/her basic information, the user may autonomously select any one of the three stages according to his/her own situation for learning.

The playing video can be obtained by recording the demonstration of a piano teacher in advance, aligning the camera with the hands of the teacher, collecting the audio played by the teacher through the microphone, making the audio into the playing video, embedding the music score content into the video in the later period, and indicating the current playing progress of the music score through the movement of a cursor on the music score or the rolling display of the music score, or through the playing progress bar of the music score and other modes. The current performance progress of the score, i.e. the currently performed notes, corresponds to the part of the score.
In addition, in the learning process, the process of video display can support automatic selection of fast-playing video or slow-playing video according to the rhythm of the target music score, and certainly, the currently played video can be paused at any time according to the selection of the user. This function is not only realized during video playback, but can also be used during playback of only the melody of the target melody. For example, when the user learns the target music score, in the process of video synchronous playing, the user selects an intelligent function in the learning mode, that is, the playing speed is adjusted according to the speed of the target music score, for example, when the melody of the target music score is faster, the playing speed is appropriately reduced; if the speed of the target music score is slower, the playing speed can be properly accelerated. Of course, this intelligent function is activated at the user's option as a preferred way for the user to select.
In addition, in the process of playing the video or audio in the learning stage, the target user can control the video or audio to be played in a required stage according to the requirement, and can also fast forward or rewind the audio or video in real time, and the functions and operations are the same as the single-point control or the segmented notification of the audio or video on the intelligent terminal. The single-point control supports clicking at any position of a target music score, the initial position of playing is set, the music score started at the current position is played continuously when clicking playing, and meanwhile, playing demonstration is carried out by two hands. The target video can be played quickly and slowly according to the rhythm, and the video can be played repeatedly. The multi-section control supports clicking at any position of the target music score, the area between two clicks is the area where the video is played currently, and meanwhile, playing demonstration is carried out by two hands. The target video can be played quickly or slowly according to the rhythm speed, and the video can be played repeatedly.
And S103, acquiring the musical instrument sound input by the target user according to the target music score.
The target user presses the corresponding keys according to the melody of the target music score in the learning process, and the intelligent terminal is connected with the intelligent piano to collect the tones of the keys pressed by the target user. It should be noted that, the intelligent terminal according to the embodiment of the present disclosure is connected to the intelligent piano in various connection manners, and may be connected in a wired manner or in a wireless manner, and the specific connection manner is not limited.

And S105, when the piano tone information input by the target user meets the evaluation requirement of the learning stage, entering the next stage according to the selection of the target user.
After the piano sound information corresponding to the keys pressed by the target user is collected, the collected piano sound information is compared with the piano sound information of the target music score, whether the collected piano sound information is consistent with the piano sound information corresponding to the target music score is judged, and whether the piano sound information played by the target user according to the target music score meets the evaluation requirement of the current learning stage is further judged. Note that the musical instrument sound information described in the present embodiment includes musical instrument sound, intonation information, rhythm information, melody information, and the like played by the target user. The evaluation requirements corresponding to different learning stages are different. For example, the evaluation requirement in the stage of identifying the music score may only require that the musical notes in the musical note information are accurate, and there is no corresponding requirement for rhythm, duration and the like, so that the collected musical note information only needs to be compared to determine whether the musical notes are accurate.
And when the piano tone information input by the target user is judged to meet the evaluation requirement of the learning stage, prompting the user to enter the next stage or practice of the next target music score, or other next operation. Therefore, in this embodiment, when the musical instrument sound information entered by the target user meets the evaluation requirement of the learning stage, the user may select to enter the next stage according to the needs of the user, where the next stage does not refer to the next learning stage, but means the next stage, and may be to end the current exercise, continue the exercise of the next music score of the current learning stage, or enter the learning of the next stage after the basic task of the current learning stage is completed, for example, enter the stage of training for improving from the stage of learning the music score.
