PURPOSE:To easily generate a rhythm sound strictly in accordance with an image and matched to the tune of a music piece by outputting a rhythm information by inference from a performance data by using a neural network. CONSTITUTION:A performance data of a music piece is input to a neural network means. A neural network is a hierarchical network and treated as a software by CPU 1. Rhythm parts are previously learned about a plural number of music pieces in correspondence with melody parts of famous music pieces in the neural network. The neural network outputs a rhythm information of rhythm accompaniment against the music piece of the performance data by inference on the basis of a plural number of parameters input to neurons I1-I11 of an input layer and a synapse weight (w) in ROM 2. Consequently, it is possible to automatically and easily create a rhythm sound based on the music piece. |
