Problems solved by technology
[0003] When performing music analysis on classical music, it is usually necessary to analyze the chord performance of classical music, but the current analysis of the chord performance of classical music is based on the analysis of chord symbols, and the chord properties such as the root tone of the chord can be obtained, but This type of analysis fails to yield information about the function of chords in classical music

The invention relates to the technical field of artificial intelligence, and particularly provides a music chord recognition method which comprises the following steps: for music data of a to-be-recognized music chord, sequentially extracting note information corresponding to each note contained in the music data, and constructing a two-dimensional matrix representation of each note based on the note information corresponding to each note; extracting note features corresponding to the notes according to the two-dimensional matrix representation of the notes; identifying chord features corresponding to the notes from different chord function identification dimensions based on the note features corresponding to the notes; combining the chord features of the same note on different chord function recognition dimensions to obtain chord combination features corresponding to the notes, and taking a feature sequence formed by the chord combination features corresponding to the notes as a music chord recognition result corresponding to the music data. The information of the music data on the chord function can be identified based on number notes.
Description
technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a music chord recognition method and device, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the continuous development of computer information technology, the application of computer technology in art is becoming more and more extensive. For example, there are a large number of Western classical music works. By establishing an automatic classical music analysis system, the study of classical music can be made more convenient, and the dissemination of classical music can have greater potential. [0003] When performing music analysis on classical music, it is usually necessary to analyze the chord performance of classical music, but the current analysis of the chord performance of classical music is based on the analysis of chord symbols, and the chord properties such as the root tone of the chord can be o...
