[0039] As shown in FIGS. 2A-3K, in an embodiment of the present application, the present application further includes an input module, the input module is configured to input one or more modes into one or more modes and send the mode setting to the control module, and the control module matches the mode setting while matching the string-pressing combination and the string-string-plucking source signal, and then plays the specified audio file through the audio playback module.

[0040] During specific operation, one or more different string-pressing matching modes are set manually, then string playing is performed, in the playing process, the control module performs the string-pressing combination and the string-string-plucking source signal preset in the matching control module in the set mode, and then the control module specifies the corresponding audio file to be played through the audio playback module according to the matched string-pressing combination and the string-string-plucking source signal; In the playing process, the control module firstly matches a preset string-pressing combination and a string-string-plucking source signal in the string playing information matching control module according to the string playing information received by the control module, the control module matches the set corresponding mode according to the matched string-pressing combination and the string-string-plucking source signal, and after the mode matching is completed, the corresponding audio file is designated to be played through the audio playback module.

[0041] In order to achieve different degrees of error correction pronunciation, the preset string-pressing combination in the control module includes a string-pressing sensor signal that must be triggered during chord playing and a string-pressing sensor signal that must not be triggered. When there are more signals that must not be triggered and included in the preset string-pressing combination, the greater the playing difficulty, the smaller the playing difficulty when the preset string-pressing sensor signals included in the preset string-pressing combination are less.

[0042] As shown in FIGS. 2A-3K, in an embodiment of this application, before the guitar is played, an input module may be further used to perform rhythm selection. After rhythm selection, during playing, when playing, the control module matches the corresponding audio file according to the selected rhythm rule when the string playing combination matches the corresponding string-pressing combination and the string-string-plucking source signal set in the string playing combination matching control module, and then plays the specified audio file through the audio playback module, wherein the playing audio files of the same chord tone with different rhythms are pre-recorded and stored in the audio playback module, the rhythm is different, and the strength of the audio file is different.

When multiple playback sources are played simultaneously, it is the sound of sweeping the string.

[0056] When the control module, the input module, the display module, and the audio playback module are all disposed on the guitar body, in another embodiment of the present application, the audio playback module has a audio playback channel

[0057] Specifically, the input module can be used to select whether the audio file playback is in single-response/single-note mode, when plucking the strings, thereby choosing between the string-plucking mode or the string-strumming mode. when the intelligent error correction guitar is in the string-plucking mode, the control module sends the specified audio file to the audio playback channel for playing according to the received signal combination of the wire plucking sensor; when the single string is plucked, the corresponding audio matched with the string signal and the string-string-plucking source signal is combined to be played through the audio playback channel, and when the intelligent error correction guitar is in the string sweeping mode, when plucking multiple strings, the audio file containing the joint recording of the corresponding audio matched with the string-pressing signal and the plurality of string-string-plucking source signals in a one-to-one mode is designated to be played through the audio playback channel, so that the condition of incomplete audio is avoided.
