Description

Musical instrument teaching system

Technical Field

The present invention relates generally to the field of music teaching. More particularly, the present invention relates to a musical instrument teaching system.

Background

The traditional musical instrument teaching mode is mostly that teacher and student's live teaching face to face. Along with the development of internet science and technology, online teaching becomes a new musical instrument teaching mode, and online teaching mainly has three kinds of modes: 1. the teacher explains the teaching materials through live video, the student exercises on own musical instrument, the teacher watches and listens to the performance of the student, and the student is remotely guided to perform in a video mode; 2. the teacher plays the explanation of the teaching materials recorded in advance through the video, the student exercises on own musical instrument, and the teacher does not watch and/or listen to the performance of the student; 3. the teacher explains the teaching materials through video playing, wherein the video contains operation prompts for playing the musical instrument, and the student plays the corresponding position according to the prompts of the video.

The above-described conventional musical instrument teaching methods and on-line teaching methods have various disadvantages. In particular, the conventional teaching manner requires that a teacher and a student are present at the same time, so that it is inconvenient for the student to practice alone without the teacher's live guidance. In addition, the online teaching mode can not enable the trainee to obtain visual guidance information directly embodied on the musical instrument, so that the remote interactive teaching can not be really realized, and the improvement on the capability of the trainee to play the musical instrument is very limited.

SUMMERY OF THE UTILITY MODEL

To address at least one or more of the above-mentioned problems in the background, the present invention provides an instrument teaching system. By the scheme provided by the utility model, the trainees performing the playing training can find the defects and the parts needing improvement in the playing process in real time, so that the playing learning effect can be greatly improved. Based on this, the present invention provides in various aspects various solutions as follows.

In one aspect, the present invention discloses a musical instrument teaching system. This musical instrument teaching system includes: a training module arranged at the musical instrument and configured to acquire a training signal generated by a trainee performing a performance operation on the musical instrument during a performance; a storage module configured to store a reference signal generated by performing a performance operation on the musical instrument; a processing module configured to generate a corrective signal for correcting the trainee performance operation according to the comparison of the training signal and a reference signal, wherein the corrective signal is associated with at least one corrective operation; and a rectification module arranged at the musical instrument and configured to: receiving the corrective signal from the processing module; and visually presenting the corrective signal to the trainee to assist the trainee in performing the corresponding corrective action.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

With the development of internet science and technology, online teaching becomes a new musical instrument teaching mode. Compared with the traditional teaching mode, the on-line remote video teaching mode does not require a teacher and a student to perform teaching activities in the same place at the same time, but has the problem that the teacher cannot comprehensively obtain specific operation information in the playing process of the student, such as specific playing position, force and the like, and the fine information cannot be accurately obtained through the on-line remote video and can not directly guide the student at a musical instrument. Based on the background, the utility model designs a musical instrument teaching system. By improving the musical instrument in the system, for example, arranging a plurality of modules for collecting performance signals and correcting the performance at the musical instrument, the system of the present invention can realize real-time acquisition of performance conditions of trainees in training and intuitively and timely guide the trainees so as to improve the performance level thereof.

Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a block diagram schematically showing the composition of an instrument teaching system 100 according to an embodiment of the present invention.

As shown in FIG. 1, the instrument teaching system 100 of the present invention may include a training module 110, a processing module 120, a storage module 130, and a remediation module 140. In one embodiment, the training module may be disposed on the musical instrument, and is used for collecting training signals generated by the trainee performing the playing operation on the musical instrument during the playing process. The storage module is used for storing reference signals generated by performing playing operation on the musical instrument. The processing module is used for generating a correction signal for correcting the performance operation of the trainee by comparing the training signal with the reference signal, wherein the correction signal is associated with at least one correction operation, and the correction operation may include: pressing a key, striking a drumhead, or striking a string, etc. The correction module is arranged on the musical instrument and is used for receiving the correction signal from the processing module and then visually presenting the correction signal to the student so as to guide the student to perform corresponding correction operation.

Fig. 2 is a block diagram schematically showing the composition of an instrument teaching system 200 according to another embodiment of the present invention.

As shown in FIG. 2, the instrument teaching system 200 may include a training module 110, a processing module 120, a storage module 130, and a rectification module 140. In one embodiment, the aforementioned training module 110 may include a detection circuit 110-1 for detecting a performance operation of a trainee at a playing zone or a tapping zone of an instrument and generating a corresponding training signal. In one embodiment, the detection circuitry may include one or more of a vibration sensor 110-11, a MEMS sensor 110-12, a magnetic induction circuit 110-13, and a light sensor 110-14 to sense or detect performance operations of the instrument by the trainee. According to different implementation scenarios, the detection circuit can be arranged below a playing area or a knocking area of the musical instrument, for example, below keys of a piano type musical instrument or a drumhead of a drum type musical instrument, so as to acquire information such as the strength, the position and the time when the keys are pressed or the drumhead is knocked in real time.

In one embodiment, the reference signal stored in the storage module 130 may be generated as follows: first, an exemplary set of signals is acquired. In one implementation scenario, a music piece may be played on a musical instrument arranged with the training module of the present invention by a player with a rich playing experience, and an exemplary signal is generated for each playing action (e.g., each press, tap, or touch) performed by the player on the musical instrument. Thus, a set of demonstration signals for the music piece, i.e. a set of demonstration signals for the music piece, is generated once per performance of the music piece. After a plurality of performances, a plurality of groups of demonstration signals of the music can be obtained through the training module. Reference signals may then be generated based on the aforementioned sets of exemplary signals. In one implementation, the plurality of sets of demonstration signals may be used as samples to perform normal distribution processing on each demonstration signal of the performance action, so as to obtain a set of reference signals for performing the music piece, which are also referred to as reference signals in the context of the present invention.

It is understood that, because the training module of the present invention is used to collect signals, the above exemplary signal set and the reference signals obtained later can be regarded as a set of performance signals generated by performing performance operations on the musical instrument at different time points. Further, the reference signal obtained in the above manner can be regarded as a standard or professional-accepted performance operation. In addition, the above-mentioned manner of obtaining the reference signal is also only exemplary and not restrictive, and different manners may be adopted according to different application scenarios or actual conditions. For example, the music played by the teacher using the training module of the present invention can be directly used as the reference signal to correct the lack of performance of the student.

In one embodiment, the aforementioned processing module 120 may be composed of a chip or a circuit with analyzing, determining and calculating capabilities, and the specific workflow thereof may be exemplarily performed as follows: first, the training signal collected by the trainee during performance is compared with the reference signal discussed above. According to various implementations, the comparative analysis herein may relate to the performance length of the music piece. Taking a trainee playing marimbas as an example, when the trainee uses the marimbas to practice four-beat music with a duration of one minute, the duration of each beat is one second, and at each beat, the training module of the utility model records a training signal. After the performance of the one-minute duration is finished, the training signal of the one-minute duration collected by the training module can be compared with the reference signal for analysis. The comparison analysis may be a second-by-second or beat-by-beat comparison, i.e. a comparison analysis of the training signal with the reference signal is performed at each beat. Assuming that the standard reference signals are 60 in one minute and the training signals collected by the training module are 50 in one minute, the processing module determines that the trainee has performed a mistake in the one minute through the comparison of the numbers, thereby generating corresponding correction signals. The performance time length of the comparative analysis may be adjusted according to the ability of the trainee. For example, for a junior student, a comparison analysis may be performed immediately after each note is played, and a corrective signal may be generated. However, for advanced trainees (who have less error probability than primary trainees), the processing module can perform a comparative analysis after the whole music performance is finished to generate a correction signal. Finally, the processing module may send the correction signal generated by comparing with the reference signal to the correction module.

Taking the example that the trainee strikes the drum to perform the performance training, when the force and/or the position of the trainee striking the drum surface are incorrect, the training module of the utility model generates a training signal different from the reference signal. In other words, the training module will collect training signals that the trainee includes information on the strength and/or position of the mistake made by the trainee during the stroke. The training signal may then be compared in the time dimension and/or coordinate dimension with a previously stored reference signal based on, for example, a remotely located processing module, to generate a corrective signal of the correct force and position of tapping the drumhead.

It can be seen that in the above exemplary workflow, the processing module functions as a teacher comparing the trainee's performance operation with the standard performance operation to find out the trainee's incorrect operation. Further, it is possible to give a correct performance guide for the aforementioned incorrect performance operation, as well as an additional overall evaluation.

In one embodiment, the orthotic module 140 may include a light assembly 140-1 that may be configured to correct the student's actions by emitting light from the light assembly. For example, a student should press a key at a certain point of time, but the key is not pressed at a prescribed point of time due to a wrong operation by the student, and a light emitting assembly disposed above the key is lit to remind the student that the correct operation should be the pressing of the key.

It will be appreciated that the visual corrective signal communicated to the trainee is equivalent to the instructor's advice against the trainee's incorrect operation. In this way, the trainees can still receive the intuitive guidance opinions directly fed back to the musical instruments in real time during the independent training. Since the actual playing operation information of the trainee comes from the musical instrument and is not obtained through other ways, the collected actual playing operation information of the trainee is more accurate, and therefore the correction signal fed back to the trainee is more accurate and effective for correcting the insufficient playing of the trainee. In addition, the guidance opinions are established on the basis of the actual performance operation information of the trainees, so that the guidance opinions are more targeted, and the training guidance effect is better.

According to various implementation scenarios, the musical instrument teaching system 200 of the present invention may further include a display terminal 150 for outputting performance instruction information and/or correction signals for instructing the trainee to perform to the trainee. Alternatively, the performance indicating information and/or the correcting signal may be a text signal, an audio signal, a video signal, or a combination thereof.

Fig. 3 is a schematic structural diagram showing a key block 300 of a musical instrument of the piano type according to an embodiment of the present invention.

As shown in fig. 3, a key area 300 of a musical instrument of the piano type according to an embodiment of the present invention may include keys 301, a detection circuit 302, a support panel 303, and light emitting components 304. Specifically, the detection circuit 302 disposed below the key 301 in fig. 3 is a vibration sensor. Further, a vibration sensor is disposed on the support panel 303. In addition, a light emitting assembly 304 is disposed above the key.

In one embodiment, when the key is touched, the vibration sensor below the key will acquire a corresponding amount of mechanical vibration, which is received by the mechanical part of the vibration sensor to form another amount of mechanical vibration suitable for transformation. Finally, the mechanical vibration amount is converted into an electric signal by an electromechanical conversion portion of the vibration sensor. Further, the training module can obtain the position of the touched key through the serial number of the vibration sensor, and obtain the force touching the key through the electric signal output by the vibration sensor, so as to output a position signal and a force signal, and the training signal collected by the detection circuit at the moment contains the position signal and the force signal.

In different application scenarios, the detection circuit may also be one or more of a pressure sensor, a magnetic induction circuit, a capacitance induction circuit, an ultrasonic sensor, and a light sensor, wherein the type, number, and layout of the detection circuit may be configured according to the type of the musical instrument. For example, for guitar and koto based instruments, such as those used to play strings, the sensing circuit may be an optical sensor that senses the location and time at which the string is played through the change in light near the string. In addition, the detection circuit of the drum instrument may be a magnetic induction circuit or the like.

Fig. 4 is a schematic structural view showing a striking zone 400 of a drum-like musical instrument according to an embodiment of the present invention.

As shown in fig. 4, the striking area 400 of the drum-like musical instrument according to the embodiment of the present invention may include a drumhead 401, a detection circuit 402, a support panel, and the like, wherein the detection circuit may be disposed closely under the drumhead to better detect a signal generated by a trainee's tap on the drumhead.

As shown in FIG. 4, in one embodiment, the detection circuit 402 in FIG. 4 may be a magnetic induction zone. In one scenario, each magnetic induction zone may include a respective magnetic induction circuit to generate the associated magnetic induction signal when the magnetic induction zone is triggered. The magnetic induction circuit may include a circuit composed of magnetic induction coils (the magnetic induction coils are represented in the form of a grid in fig. 4). When the magnetic induction coil is electrified, an excitation alternating electromagnetic field is generated in the magnetic induction area based on the electromagnetic induction principle. Further, when the magnetic induction area is triggered, the magnetic flux of the alternating magnetic field changes, the training module can calculate the position of the magnetic induction area through the change of the magnetic flux, and then position signals are output.

Further, the training module may also determine the way the trainee actually operates by calculating the change in magnetic flux. The operation modes of different musical instruments are different, and the operation modes of the drum-like musical instrument for the present embodiment may include: striking, drawing across, or striking the drumhead. In this mode of operation, the training signal collected by the detection circuit may comprise a position signal and an operation mode signal. In addition, a force signal of striking the drumhead can also be obtained by arranging a pressure sensor under the drumhead.

In one implementation scenario, the detection circuit may further include a timer to detect whether the student operates accurately at each time point during the performance and whether the overall performance time is qualified. For example, a key should be pressed at 18 th second during the playing process, but when the 18 th second is counted by the timer, the key is not pressed, which indicates that the student operates incorrectly at the moment, and the training module collects the incorrect operation. For example, if the whole performance time of a tune is 3 minutes and 20 seconds, but the actual performance time of the trainee is 3 minutes and 18 seconds, it means that the trainee is not performing properly, and there is a certain time point or points where there is no misoperation. At this time, the training module will collect the misoperation at a certain time point/points, and will also collect the overall performance time difference of "2 seconds". In addition, the tempo signal may be a time point of each performance operation, which indicates that the student's tempo is wrong at the time when the time point of the student's actual performance operation does not coincide with the time point in the corresponding reference signal.

As for the training signals, different kinds of detection circuits used by the utility model can acquire different kinds of training signals, so that the acquired training signals have multi-dimensional attributes. Accordingly, the reference signal and the correction signal may also be multi-dimensional, where the dimensions may include: position, force, mode of operation and tempo. The training signal, the reference signal, and the correction signal may each include one or more of a position signal, a force signal, an operation mode signal, and a rhythm signal.

In one embodiment, when the reference signal is a multi-dimensional signal, the generation process of the reference signal is as follows: first, a certain piece of music is played on a musical instrument arranged with a training module by a player having a rich experience of performance, and a set of training signals is generated every time the piece of music is played. After a plurality of performances, a plurality of groups of training signals of the music are generated. Further, the plurality of groups of training signals are used as samples, and signals on at least one dimension included in the training signals of each step of operation are processed by a normal distribution method, so that a group of multi-dimensional reference signals of the music are obtained. Accordingly, the specific workflow of the processing module is as follows: firstly, the training signal and the reference signal are compared on at least one dimension, then the training signal different from the reference signal is found out, and finally, the correction signal generated by comparing the training signal with the reference signal is sent to the correction module.

It is understood that the present invention can acquire training signals of multiple dimensions of a trainee using different kinds of detection circuits in order to more accurately guide the trainee. Meanwhile, different kinds of detection circuits can be adapted to various musical instruments. According to different application scenes, the musical instrument can be one or more of piano, electronic organ, xylophone, tremolo, marimba, chime, drum set, Chinese drum and the like.

Fig. 5 is a schematic view illustrating a structure of a light emitting assembly 500 according to an embodiment of the present invention.

As shown in fig. 5, the light emitting assembly of the present invention may include a first light emitting assembly 501, a second light emitting assembly 502, a third light emitting assembly 503, and a fourth light emitting assembly 504. According to different implementation scenarios, the number and layout of the light emitting assemblies can be configured according to the type of the musical instrument. In one embodiment, the first light emitting assembly, the second light emitting assembly, and the third light emitting assembly of fig. 5 may be disposed under the drumhead, connected to each other in a circular ring shape, and dividing the drumhead into a rim area, a middle drum area, and a center drum area. When the first light-emitting component is lightened, the correction signal is a position signal so as to remind a student that the student should knock the position of the first light-emitting component; similarly, when the second light emitting assembly or the third light emitting assembly is lightened, the student is reminded that the student should knock the position of the second light emitting assembly or the third light emitting assembly.

In one embodiment, a fourth light emitting element may be disposed on the side of the drumhead, which is a light emitting element that prompts the trainee to strike the drumhead. The light emitting component is a lamp strip and can comprise a plurality of single lamps which are connected in sequence. When the musical instrument is played, the single lamps are sequentially lightened from one end of the lamp belt, and the more the single lamps are lightened, the stronger the strength signal is; when the force needs to reach the maximum, all the single lamps are lightened; when the force signal is not received, the light strip is not illuminated.

It is understood that, in the case of the light emitting assembly, the aforementioned rectifying module converts the rectifying signal into a control signal for controlling the light emitting assembly, and further, the light emitting assembly may be disposed on a musical instrument, which can emit a light signal according to the control signal, so that a trainee can be intuitively and directly guided to perform. According to different application scenes, the correction signals can be of various types, various correction signals can be converted into different control signals, and the light-emitting component further emits diversified light signals according to the different control signals, wherein different light signals represent different prompts. When playing a musical instrument, the trainee can be reminded of the correctness of the key pressed by the key by the state of the light emitting assembly arranged above the key. For example, if a key is not depressed at a specified point in time, the light emitting assembly above the key will be illuminated to alert the trainee that the key needs to be depressed at that point in time. In addition, the light emitting component will be turned off within a certain time period after being turned on, and the time period may be 0.5 seconds, for example.

In different application scenarios, the light emitting assembly may be a single lamp, or a lamp group consisting of a plurality of single lamps, or a liquid crystal display, an optical assembly consisting of optical fibers, or other devices that can emit light through electrical signals or optical signals. Further, the light emitting assembly may emit one color of light or a plurality of colors of light, and may communicate different corrective signals to the trainee through the change of colors. In one embodiment, when the light is orange, it indicates that the tapping force is too great; when the light is red, the operation is indicated but not operated; when the light is yellow, the operation strength is not enough; when the light is blue, the operation mode is not equal.

In one embodiment, the shape of the different light emitting components may also be different. As shown in fig. 5, the first, second and third light emitting assemblies are shaped to fit the drumhead and are removably attached to the drumhead. The teaching system can flexibly transfer the first light-emitting component, the second light-emitting component, the third light-emitting component and the fourth light-emitting component to different drumheads according to the actual requirements of users, thereby improving the adaptation rate and the utilization rate of the musical instrument teaching system and being convenient for sale or rent.

It can be seen that the correction signal can be used for correcting the operation position, force, operation mode, rhythm and the like of the trainee during playing, and the light emitting component indicates different correction operations to the trainee in different light emitting modes. The musical instrument teaching system of the utility model can adapt to various musical instruments through diversified correction signals, thereby accurately guiding the performance of trainees from multiple dimensions.

In another embodiment, the diversified correction signals can be transmitted to the trainee through the form of light emission of the light emitting component, and can also be transmitted to the trainee through the display terminal. The display terminal can be a television, a computer, a mobile phone or a projection device, and the like, can be used for outputting performance instruction information for guiding performance to a student, and can also be used for playing performance videos to the student. The performance video may include, but is not limited to, the following information: 1. a target musical score or note; 2. demonstration of the expression method of the target music score or note; 3. accompanied with information such as the performance progress of the above-mentioned target score or note. Further, the performance indication information and the correction signal may be an evaluation report in the form of a text.

When the musical instrument teaching system is practically applied to teaching, a correction signal can be fed back to a beginner in a real-time feedback mode in a light-emitting mode of the light-emitting component, so that the beginner can immediately correct errors in the learning process. In addition, the trainees with certain experiences can be fed back to the trainees in an evaluation report mode after the whole performance is finished, and the trainees can correct and practice errors indicated in the report.

In one embodiment, the storage module and the processing module of the teaching system of the present invention can be arranged in a stand-alone system, a server system or a cloud server system according to actual needs. As can be seen from the description herein, the arrangement of the storage module and the processing module of the present invention is very flexible, both can be arranged locally (i.e. at one location with the instrument) or remotely (i.e. at a greater distance from the instrument), and both can be arranged at the same location, or in separate arrangements.

Fig. 6 is a flowchart illustrating an instrument teaching method 600 according to an embodiment of the present invention.

As shown in FIG. 6, in one embodiment, the method 600 for instrumental teaching of the present invention may comprise the steps of:

step S601: collecting training signals generated by the trainees performing playing operations on the musical instrument in the playing process through a detection circuit arranged at the musical instrument;

step S602: the training module sends the training signal to a processing module;

step S603: the processing module acquires the reference signal from the storage module. As described previously, the reference signal here may be a performance operation signal that the performance teacher performed in advance and is correctly collected;

step S604: the processing module compares the reference signal to the training signal (including the various required analysis and processing described above as examples) to derive a corrective signal for the correcting student. In one implementation scenario, the training signal may be compared to the reference signal in the time dimension (i.e., with reference to the same point in time). When the training signal and the reference signal at the same time point are different, the reference signal can be directly used as a correction signal to correct the performance error of the student;

step S605: and sending the analyzed correction signal to a correction module as a result. The analysis result here includes the specific type of the reference signal, such as a position signal, a force signal, or a rhythm signal; in addition, the analysis result can also comprise specific strength values of the strength signal;

step S606: the correction module receives the correction signal and sends the correction signal to the corresponding light-emitting component. For example: if the correction signal is a position signal, sending the correction signal to a light-emitting component for prompting the position; if the correction signal is a force signal, the correction signal is sent to a luminous component for prompting force, and meanwhile, the luminous component for prompting force performs corresponding lighting operation according to a specific force value contained in the correction signal; further, the light-emitting component emits light according to the indication of the correction signal, and the correction signal is visually presented to the student so as to assist the student in executing corresponding correction operation.

In one implementation scenario, the correction signal obtained in step S604 can be fed back to the trainee in real time, i.e. when the trainee performs an incorrect operation, the lighting assembly is immediately made to emit a corresponding light to prompt the trainee. In another embodiment, the processing module may also integrate the correction signals generated during the performance of the entire piece of music into an evaluation signal after the performance of the entire piece of music has ended. In one embodiment, the evaluation signal may comprise a set of correction signals distributed over different points in time. After the performance is over, the processing module may generate an evaluation report based on the evaluation signal and send the evaluation report to the trainee to indicate errors and deficiencies in the performance to the trainee in the form of the evaluation report.

The operation of the musical instrument teaching system of the present invention will be further described below by taking as an example the practice of performance by trainees on a piano. It should be noted that, for the purpose of simplifying the description below, the reference signal is regarded as the correction signal of the present invention, that is, when there is a difference between the training signal and the reference signal, the reference signal is directly selected as the correction signal for correcting the performance operation of the trainee. Further, all be provided with the LED lamp that is used for indicateing to play the position and be used for indicateing the LED lamp area according to the pressure degree on every key of this piano. The LED lamp strip comprises 10 LED lamps which are arranged in parallel, the LED lamps in the LED lamp strip represent 1 cattle of force when being lightened completely, nine LED lamps in the LED lamp strip represent 0.9 cattle of force when being lightened, and the like, and one LED lamp strip represents 0.1 cattle of force when being lightened. A timer and a pressure sensor are arranged under the keys.

Firstly, a student plays a piece of music, and rhythm signals, position signals and force signals generated in the playing process are collected by a timer and a pressure sensor in a training module; then, the training module sends the rhythm signal, the position signal and the strength signal to a processing module; the processing module retrieves from the memory module a reference signal for the piece of music, which also includes a tempo signal, a position signal and a strength signal. Then, the processing module respectively compares and analyzes the rhythm signal, the position signal and the force signal at each time point in the playing process of the trainee with the rhythm signal, the position signal and the force signal in the reference signal at the same time point, namely the rhythm signal of the training signal is compared with the rhythm signal of the reference signal; comparing the position signal of the training signal with the position signal of the reference signal; the strength signal of the training signal is compared with the strength signal of the reference signal.

Through the above comparative analysis, when the signal of any dimension (the dimension includes rhythm, position and strength) in the training signal is different from the signal of the dimension in the reference signal at the same time point, the signal of the dimension in the reference signal is used as the correction signal. For example, at the time point of the zeroth 2 nd minute 5 seconds of the music piece, the trainee should play the D key of the bass region, but detected by the timer and the pressure sensor, at the time point when the C key of the bass region is pressed and the D key of the bass region is not pressed, the position signal of the training signal is different from the position signal of the reference signal. The correction signal is thus the position signal of the reference signal at the time point of 5 seconds at the 2 nd zero. Further, the processing module sends the position signal as a correction signal to a light-emitting component for prompting the operation position, namely an LED lamp above the D key in the bass region. Finally, the LED lamp above the D key is illuminated to alert the student that the key should be depressed.

For another example, at the time point of 8 seconds at the 1 st minute zero of the music piece, the trainee should play the a key in the bass region with a force of 1 newton, but detected by the timer and the pressure sensor, at the time point when the a key in the bass region is pressed with a force of 0.5 newton, the strength signal of the training signal is different from the strength signal of the reference signal. Therefore, the correction signal is the strength signal of the reference signal at the time point of the 1 st zero 8 seconds. Further, the processing module sends the force signal (including the force value) as a correction signal to a light-emitting component for prompting the operation force, namely the LED lamp strip above the key A in the bass region. Finally, the LED strip above the a key was fully lit to prompt the trainee that the key should be depressed with greater force at the 1 st minute-8 second time point.

The method for teaching the musical instrument provided by the scheme collects the training signals of the trainee in the playing and practicing process in real time, and simultaneously feeds back the intuitive correction signals for guiding the trainee, so that the trainee can still receive the intuitive guidance directly reflected to the musical instrument in real time during the independent training, thereby realizing the bidirectional communication between teaching and learning and obtaining good teaching effect.
