Intelligent error correction method for electronic organ teaching

Abstract

The invention provides an intelligent error correction method for electronic organ teaching. The method comprises the steps: selecting a to-be-played music, loading a demonstration playing MIDI, starting music score moving, by the user, pressing the music score to play the electronic organ, sending the corresponding pitch, the key pressing time point and the key loosening time point back to an error correction program in real time in an MIDI data communication mode, and in the error correction program, comparing the acquired playing pitch, the key pressing time point and the key loosening timepoint with corresponding demonstration playing MIDI data. According to the intelligent error correction method for electronic organ teaching, the MIDI data communication mode is adopted, data acquisition accuracy is high, the method is suitable for error correction of high-frequency and high-speed playing, error correction latitude is more complete, various specific types of errors can be accurately corrected, and an error correction comparison object is more scientific and reasonable and is closer to actual on-site playing.

Description

technical field [0001] The invention belongs to the field of music education, and in particular relates to an intelligent error correction method used in double row key teaching. Background technique [0002] With the development of Internet technology, more and more Internet technology is applied to the field of music education. At present, there are many teaching apps in the fields of piano, guitar, electric drum, etc., which can realize simple notation and error correction. [0003] And double-row key is divided into upper, lower, pin three-layer keyboard, has multiple data channels, because the particularity of double-row key musical instrument, there is no better networked teaching method at present. The existing learning of double-row keys is to look at the paper mass spectrum, and then play on the double-row keys. Whether the performance is correct or not can only be heard by ears, and it is impossible to give real-time feedback on whether the performance is correct ...

AI Technical Summary

Problems solved by technology

[0005] First, the accuracy of error correction is poor. Many musical instruments collect user performance information through pickups or built-in audio collection modules. For fast, pitch-intensive music sections, the accuracy of pickup collection will be greatly reduced, resulting in error correction accuracy. decline;

[0006] The second is that the error correction latitude is not complete enough. The traditional error correction method only corrects the pitch and time value, and the error correction for the rhythm is not complete enough, and it is impossible to realize the early, late, loose early, loose late, and missing. At the same time, the common object of error correction and comparison is the pitch and time value information in the MusicXML file of the score. If the pitch and time value of the MusicXML are compared, the performance is relatively mechanized. , which is quite different from the actual performance, and the teaching effect is poor
