Embodiment

[0059] As shown in the following process:

[0060] A. After installing the APP on the mobile phone, the user selects the type of accompaniment or musical instruments and other parameters (by default, it can be automatically selected randomly), and then turns on the recording function to sing songs. Then, by clicking on the audition, the recording file and other parameters input by the user are uploaded to the server.

[0061] B. After receiving the file and parameters, the server converts the audio file into MIDI format through an algorithm and optimizes it. Then use the method of this patent to match a perfect MIDI accompaniment according to the parameters specified by the user. Then synthesize the MIDI into an audio file and send it to the mobile phone.

[0062] C. At this time, the client will prompt the user that the composition is completed, and the user can listen to it.

Abstract

Artificial music composing for a song is a very difficult and big job. In a traditional method, if a fitting degree between the accompaniment and human voice is high, the effect is good and the cost is high. Software on the internet integrates part of playing templates, but, in order to make a complete song, some professionals are needed to choose suitable chords and instruments and to make changes of music levels during song production. The method for automatically composing an accompaniment for the melody comprises steps of receiving an MIDI file provided by a user and parameters of various instrument types, dividing bars according to a speed to obtain note information, determining tonality through analysis, determining a musical mode, composing a chord and optimizing an effect, matching instruments and generating the MIDI. The method and system for automatically composing accompaniment for the melody turn a burdensome artificial processing process to a fast and efficient automatic intelligent accompaniment composing method. The user can try multiple matching modes in a short time, can modify any instruments and chords at anytime, can listen to a final effect during operation and stores the accompaniment as an audio file.
