PURPOSE:To obtain the automatic music composing machine that makes a quick system response and generates a melody which matches the progress of music (chord progress) and is based upon musical knowledge. CONSTITUTION:A 1st current pitch candidate is generated according to a last pitch 202 and a random number 204. A sound kind and interval series generation block 208 classifies the kind of sound of the current pitch candidate and the interval from the last melody sound according to the music progress (current tonality 210 and current chord 212) in process and evaluates a melody pattern consisting of the current pitch candidate and a precedent melody which is generated yet. A matching module 214 retrieves the evaluated melody pattern in a melody pattern rule base 216. In case of a failure in retrieval, generation and retrieval are repeated through a next candidate generation module 220. A current pitch is decided on retrieval success. |
