Abstract

PURPOSE: To simulate features of player's or composer's accompaniment line determination process by estimating a fundamental tone of a noticed section in a form dependent upon past fundamental tones in consideration of a musical condition given to this section and estimating it in a form independent of past fundamental tones. CONSTITUTION: Past-dependent fundamental tone estimation means 7, 10, 11, and 17 which estimate the fundamental tone of the noticed section in the form dependent upon past fundamental tones of sections in accordance with the musical condition of this section and past-independent fundamental tone estimation means 9, 15, and 16 which estimate it in the form independent of past fundamental tones of sections are provided. Both of means function so as to complement each other to generate a musical fundamental tone progress which cannot be obtained a fundamental tone determination device with a single estimation logic. Thus, features of composer's or player's accompaniment line determination are expressed well, and the fundamental tone progress on a level which cannot be achieved by conventional accompaniment line fundamental tone determination technique is generated by artificially intelligent approach taking the musical condition into consideration.
