Method for generating musical score, electronic device, and readable storage medium

An electronic device, comprising a memory and a processor, wherein

• the memory is configured to store a computer program;
• and
• the processor is configured to execute the computer program to implement a method for generating a music score, the method comprises:
• obtaining a target audio;
• generating a chromagram of the target audio corresponding to each of pitch classes;
• identifying chords of the target audio based on the chromagram, to obtain chord information;
• detecting a mode of the target audio to obtain original mode information;
• detecting a rhythm of the target audio to obtain a quantity of beats;
• identifying a beat type of each of audio frames of the target audio;
• determining a time signature of the target audio based on a correspondence relationship between a beat type and a time signature;
• and
• performing music score rendering based on the chord information, the original mode information, the quantity of beats and the time signature of the target audio, to obtain a target music score.

A computer readable storage medium, storing a computer program, wherein the computer program, when executed by a processor, implements a method for generating a music score, the method comprises:

• obtaining a target audio;
• generating a chromagram of the target audio corresponding to each of pitch classes;
• identifying chords of the target audio based on the chromagram, to obtain chord information;
• detecting a mode of the target audio to obtain original mode information;
• detecting a rhythm of the target audio to obtain a quantity of beats;
• identifying a beat type of each of audio frames of the target audio;
• determining a time signature of the target audio based on a correspondence relationship between a beat type and a time signature;
• and
• performing music score rendering based on the chord information, the original mode information, the quantity of beats and the time signature of the target audio, to obtain a target music score.
