The invention discloses a self-adaptive music generation method based on mobile phone shaking. The self-adaptive music generation method comprises the following steps that S1. the shaking action of a mobile phone is detected; S2. a Riff set corresponding to the shaking action of the mobile phone is screened out of a music database; S3. the coordination degree of all the material of the screen-out Riff set is optimized so that preliminary pure music is formed; S4. the screen-out Riff set is inputted to an effector to be processed; and S5 the finally generated pure music is outputted. According to the self-adaptive music generation method based on mobile phone shaking, the corresponding music material is detected and screened out through the shaking tracks of the mobile phone, and optimization and effect insertion are performed on the screen-out music material and the finally generated music is obtained so that the limitation that music can only be created by professionals can be broken through, and everyone is enabled to participate in music creation.
