  • Computer music production is an essential branch of computer technology in artistic creation. This is an interdisciplinarysubject with information science and art. This paper proposes a creation model for digital music with first-orderinhomogeneous first-order constant coefficient linear differential equations. This mode includes acoustic modes forwaveform envelopes and bands. It has a straight-line mapping of phonetic patterns and rhythmic patterns. Then this paperuses the signal reconstruction principle and iterative extrapolation method to restore the signal in the frequency domainto obtain the simulated music. The experimental results show that this digital music creation model of inhomogeneousfirst-order constant coefficient linear differentiation can save a lot of labor costs. And this way can improve the audioquality and output effect. Compared with the undetermined factor method and the Laplace transform method inconventional advanced mathematics, the inhomogeneous first-order constant coefficient linear differentiation is moreconvenient in music composition
