The guitar 1 comprises a fretboard module 2, strings 3, a trigger detection device 4 and a muting device 5. The fretboard module 2 comprises a plurality of frets 201, and different frets 201 correspond to different target tones. The trigger detection device 4 is made of piezoelectric ceramic material, which can be a piezoelectric cable or a piezoelectric buzzer. The piezoelectric material can convert the vibration signal of the strings 2 into an alternating current electrical signal, and through a charging and discharging circuit, the generated electrical signal is converted into a regular direct current signal similar to a right-angled triangle wave, which is convenient for the processor 601 to detect. In addition, a drum machine is provided to provide percussion accompaniment, and six LEDs are used to indicate the rhythm.

[0050] Those skilled in the art can understand that Figure 2 the structure shown in Fig. 1 does not constitute a limitation on the guitar 1, and can include more or fewer components than those shown in the figure, or combine certain components, or arrange different components.

[0051] Referring to Figure 2 , Figure 2 Fig. 2 is a structural schematic diagram of a hardware operating environment involved in the guitar scheme according to the embodiment of the present application. As shown in Figure 2 , the guitar 1 can comprise a guitar control device 6, a fretboard module 2 and strings 3, wherein the strings 3 and the fretboard module 2 are connected to the guitar control device 6.

[0052] The guitar control device 6 can comprise a processor 601, such as a central processing unit (CPU) or a chip capable of digital signal processing (DSP), a communication bus 602 and a memory 603. The communication bus 602 is used to realize the connection and communication between the components. The memory 603 can be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk memory. The memory 603 can also be a storage device independent of the aforementioned processor 601.

[0053] As shown in Figure 2 , the memory 603 as a storage medium can comprise an operating system, a data storage module, a sound synthesis module, a signal processing module and a guitar control program.

[0054] In Figure 2In the guitar control device shown, the processor 601 and the memory 602 in the guitar control device of the present application can be arranged in the guitar control device, and the guitar control program stored in the memory 603 is called by the processor 1001, and the guitar control method provided by the embodiment of the present application is executed.

[0055] The embodiment of the present application provides a guitar control method, which refers to Figure 3 , Figure 3 The embodiment of the present application provides a guitar control method, which refers to

[0056] In the embodiment, the guitar control method comprises:

[0057] Step S10, when the first trigger signal of the string is detected, the pressing detection signal of the fretboard module is acquired;

[0058] The first trigger signal here refers to the trigger signal generated by plucking the string, and the fret here can be a button, a key or the like. The pressing detection signal here refers to the signal generated by pressing the fret of the fretboard module.

[0059] Step S20, determining the target fret pressed in the plurality of frets according to the pressing detection signal;

[0060] Since the signals generated by pressing different frets are not the same, the target fret pressed in the plurality of frets can be determined according to the pressing detection signal.

[0061] Step S30, determining the first target chord according to the target pitch corresponding to all the target frets;

[0062] Since different target frets correspond to different target pitches, the first target chord can be determined according to the target pitch.

[0063] Step S40, playing the first target chord.

[0064] Here, the string is not used for sounding, but the first target chord is played through the sounding device.

[0065] In the embodiment, compared with the existing beginner guitar which needs to press a plurality of string and fret positions and pluck a plurality of strings to emit a chord accompaniment sound pattern, the present application determines the chord playing time when the first trigger signal is detected, and determines not a single note but a chord directly through the pressing detection signal, thereby simplifying the step of determining the chord by the fret, and reducing the difficulty of playing the chord and the difficulty of playing the guitar.

[0066] Further, based on the first embodiment, the second embodiment of the guitar control method of the present application is provided, which refers toFigure 4 , the step of obtaining the pressing detection signal of the fretboard module when the first trigger signal of the string is detected, further comprises:

[0067] Step S01, obtaining the main pitch of the guitar, taking the main pitch as the main tone and determining the preselected pitch corresponding to each of the frets according to the natural major scale;

[0068] The main pitch here can be C, C#, D, D#, etc. The main tone here is the core of a mode. Specifically, when the main tone is C, it is C major, and the preselected pitch determined according to the natural major scale includes C, D, E, F, G, A, and B. When the main tone is D, the preselected pitch determined according to the natural major scale includes D, E, #F, G, A, B, and #C. In this embodiment, the number of frets can be 7, and each fret corresponds to a preselected pitch. In other embodiments, the number of frets can be 6, and when no fret is pressed, a preselected pitch is selected. In other embodiments, the preselected pitch can be determined according to the natural scale, and the arrangement order can be different.

[0069] Step S02, when the pitch of the preselected pitch is within a preset pitch interval, determining the preselected pitch as the target pitch corresponding to the fret;

[0070] In this embodiment, the preset pitch interval includes 12 pitches, and 60 represents the pitch of central C. The preset pitch interval is 40 to 51. When the pitch of the preselected pitch is within the preset pitch interval, the preselected pitch is determined as the target pitch corresponding to the fret.

[0071] Step S03, when the pitch of the preselected pitch is higher than the preset pitch interval, lowering the pitch of the preselected pitch to obtain the target pitch corresponding to the fret.

[0072] Here, the pitch of the preselected pitch is lowered by 1 octave as the step size of lowering the pitch, so that the preselected pitch is within the preset pitch interval, and the target pitch corresponding to the fret is obtained.

[0073] In this embodiment, compared with the special positions of the strings of the guitar, the preselected pitch is determined by the natural scale, which is easier for beginners to understand, remember and master, thereby reducing the difficulty of playing the guitar.

[0074] Further, based on any of the above embodiments, a third embodiment of the guitar control method of the present application is proposed, in which Figure 5 , the step of determining the first target chord according to the target pitches corresponding to all the target frets comprises:

[0075] Step S31, determining the corresponding chord type according to the number and arrangement characteristics of the target note;

[0076] The chord type here includes: MAJOR, MINOR, DOMINANT7, MINOR7B5, etc. Specifically, the chord type can be determined by establishing a corresponding table according to the number and arrangement characteristics of the target note. The corresponding table is as follows:

[0077]

[0078] In other embodiments, the chord type can also include MAJOR7, MINOR7, etc. The number of target notes can be 3 or more. The arrangement characteristics can also be that the target notes are spaced or adjacent, etc.

[0079] Step S32, determining one of the target tones as the chord root of the first target chord;

[0080] When the number of target notes is 1, the chord root is the target tone corresponding to the target note. When the number of target notes is greater than 1, the chord root can be determined according to a preset rule. Specifically, when two adjacent notes are pressed, the chord root is determined to be the target tone corresponding to the earlier note.

[0081] Step S33, determining the first target chord according to the chord type and the chord root.

[0082] The target tone of the first target chord is determined according to the chord root and the chord type. Specifically, the target tone of the first target chord can be determined by querying a table. Specifically, when the chord type is MAJOR, the table for determining the target tone according to the root tone is as follows (the pitch in the table is represented by the central C as 60):

[0083]

[0084] For the acoustic guitar, the chord root note is generally played on the 4th to 6th string of the guitar, and other target notes are generally played on the 1st to 3rd string, so the above only lists the pitch of the root note and the pitches of the 1st, 2nd and 3rd strings. Therefore, the target chord can be determined according to the chord type and the root note. In other embodiments, a list of associations between the frets and the target chords can be established to determine the target chord through the list of associations. Specifically, in the free playing mode, different chord fingering corresponding to different chords can be set for different styles to be played, for example, in the main tone C, the pop / folk style adds D chord, Fm chord and A chord, and the fingering is to press the first fret and the second fret at the same time, press the third fret and the fourth fret at the same time, and press the fifth fret and the sixth fret at the same time. The Latin style adds D7 chord, Fm7 chord and A7 chord, and the fingering is to press the first fret and the second fret at the same time, press the third fret and the fourth fret at the same time, and press the fifth fret and the sixth fret at the same time.

[0085] In the embodiment, the first target chord is determined by the chord type and the chord root note, so that the chords that need to be used during playing can be determined by the number and arrangement characteristics of the target frets, and the chords can be played without using complex left-hand fingering, thereby reducing the difficulty of playing chords and the difficulty of guitar playing.

[0086] Further, based on any one of the above embodiments, a fourth embodiment of the guitar control method of the present application is proposed. In the embodiment, the step of playing the first target chord comprises:

[0087] determining the playing order of the target notes in the first target chord according to a preset rhythm type;

[0088] playing the first target chord according to the playing order.

[0089] In the guitar playing, there is a playing method of the broken chord, and the target notes in the first target chord can be played in different orders. In other embodiments, the playing order of the target notes included in the first target chord can be determined according to the order of the first trigger signal and the second trigger signal to be played.

[0090] In the embodiment, the playing order is determined by the preset rhythm type, thereby increasing the playing method and improving the flexibility of guitar playing.

[0091] Further, based on any one of the above embodiments, a fifth embodiment of the guitar control method of the present application is proposed. In the embodiment, after the step of obtaining the pressing detection signal of the fretboard module when the first trigger signal of the string is detected, the method further comprises:

[0092] stopping detecting the first trigger signal of the string and starting timing to obtain a timing duration;

[0093] The step of playing the first target chord further comprises:

[0094] When the timing duration is greater than or equal to a first preset duration, the detection of the first trigger signal is started, and the step of acquiring the pressing detection signal of the fretboard module when the first trigger signal of the string is detected is returned to be executed.

[0095] In the embodiment, the string refers to all strings of the guitar. Since the speed of human performance is limited, the first preset duration can be determined by determining the fastest performance speed in the performance process of an ordinary person. In other embodiments, the voltage greater than the voltage threshold needs to be collected within the first preset time after triggering, and the voltage threshold can be determined according to the maximum voltage of the last trigger signal.

[0096] In the embodiment, the first preset duration is set to solve the problem of secondary triggering caused by the first trigger signal being not ideal or misstruck, thereby improving the stability of the guitar performance.

[0097] Further, based on any of the above embodiments, a sixth embodiment of the guitar control method of the present application is provided. In the embodiment, the step of playing the first target chord comprises:

[0098] determining an accompaniment pattern according to a preset rhythm type;

[0099] determining the playing step number of the first target chord, the corresponding note of each step, and the playing time of each step according to the accompaniment pattern;

[0100] playing the first target chord according to the playing step number, the corresponding note of each step, and the playing time.

[0101] In the embodiment, it belongs to a full-automatic mode. The accompaniment pattern of each rhythm is determined according to the preset rhythm type. The playing step number of the first target chord, the corresponding note of each step, and the corresponding playing time of each step are determined in a complete rhythm. The corresponding note of the first target chord is played according to the playing step number and the corresponding note of each step according to the playing time. Here, the playing step number, the corresponding note of each step, and the playing time are determined by the accompaniment pattern.

[0102] In the embodiment, the playing of the first target chord is controlled according to the accompaniment pattern, so that the complete rhythm of the first target chord can be played when the string is strummed once, thereby reducing the difficulty of the guitar performance.

[0103] Further, based on any one of the first embodiment to the fifth embodiment, the seventh embodiment of the guitar control method is proposed. In the embodiment, the step of playing the first target chord includes:

[0104] obtaining a detection time difference between the first trigger signal and a second trigger signal, the second trigger signal being a last trigger signal of the string detected before the first trigger signal;

[0105] determining a target playing mode of the first target chord according to the detection time difference;

[0106] playing the first target chord in the target playing mode.

[0107] In the embodiment, the second trigger signal can be on a different string from the first trigger signal, and the target playing mode can be determined according to the detection time difference, which affects the playing effect of the first target chord. Specifically, when the number of strings is 2 or more, each string is detected in the first trigger signal, and when the player quickly plucks two or more strings, the detection time difference between the first trigger signal and the second trigger signal is obtained, so as to determine the target playing mode of the first target chord. It should be noted that in the embodiment, the step of stopping detecting the first trigger signal of the string and starting timing, when the timing duration is greater than or equal to a first preset duration, the step of starting to detect the first trigger signal is for the first trigger signal of the same string, that is, when the first trigger signal and the second trigger signal are located on different strings, the detection time difference can be less than the first preset duration. In other embodiments, different target playing modes can be determined according to the strength of plucking.

[0108] In the embodiment, the target playing mode is determined by the detection time difference, so that the speed of plucking affects the performance effect of the first target chord during playing, and the flexibility of the guitar function is improved.

[0109] Further, the step of determining the target playing mode of the first target chord according to the detection time difference includes:

[0110] when the detection time difference is greater than a second preset duration, determining a broken chord as the target playing mode;

[0111] when the detection time difference is less than or equal to the second preset duration and greater than a third preset duration, determining a tremolo as the target playing mode;

[0112] when the detection time difference is less than or equal to the third preset duration, determining a sweep as the target playing mode;

[0113] wherein the second preset time length is greater than the third preset time length.

[0114] In the embodiment, when the number of strings is 1, the third preset time length is greater than the first preset time length. The performance of the broken chord can be generally divided into the root note and other notes, and the other notes are the target tone. The arpeggio is generally played from the low string to the high string in order. The speed of a fast song is 120 BPM, so the time of one beat is 500 ms, and the time of 1 / 4 beat is 125 ms. Since the broken chord is rarely played for 1 / 4 beat, the second preset time length can be set as 100 ms. When the detected time difference is equal to or less than 100 ms and greater than the third preset time length, the effect of the arpeggio is played, so that the arpeggio effect can be realized by using two strings. When the performance mode is the sweep, the preset rhythm type corresponding to the chord to be played by the sweep is modified to the rhythm type of the sweep, and the sample of the sweep is played. In other embodiments, a control button can be provided to control the stop of playing, control the playing of the muffled sound, control the playing of the overtone, etc. Specifically, when the control button is pressed, all the tones being played are turned off. When the control button is pressed for a fourth preset time length, the tone of the muffled sound effect is played when there is a trigger signal. When the control button is in the pressed state before the first trigger signal is detected, and the control button changes from the pressed state to the unpressed state after the first trigger signal is detected, the corresponding overtone of the first target chord is played.

[0115] In the embodiment, the time difference is compared with the second preset time length and the third preset time length to determine the use of different performance modes, so as to improve the flexibility of the performance of the chord by the guitar.

[0116] In addition, the embodiment of the present application also provides a storage medium, and the storage medium stores a guitar control program. When the guitar control program is executed by a processor, the steps of the guitar control method embodiment according to any one of the above are implemented.
