PURPOSE:To extremely exactly evaluate the result of musical performance with a simple arithmetic processing by applying a fuzzy inference. CONSTITUTION:A theme melody suitable for user's own musical performance level is set by a setting switch (step S3), a musical performance of set melody data is started and an error counter measurement processing is executed (step S5), and based on the number of times of erroneous musical performance and the number of times of practice, an operation of fuzzy rules A, B, C, D and E is executed and adaptation to a membership function is obtained (steps S7-11). Thereafter, a MAX operation i.e., OR processing is executed (step S12), and also, by executing a centroidal calculation, defuzzy processing is executed (step S13). In such a way, by a fuzzy inference, a level P of a player is obtained, and comparing with the previous evaluation level FL (step S15), its evaluation contents are displayed (step S16-step S18). |
