CHORD PROGRESSION INFORMATION GENERATION APPARATUS AND PROGRAM FOR IMPLEMENTING CHORD PROGRESSION INFORMATION GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a chord progression generation apparatus allowing users having no knowledge of chords to easily generate chord progression information in the rhythm of music data to be generated, and a program for implementing a chord progression information generation method.SOLUTION: When chord progression information is generated on the basis of reference origin chord chart data 100a, an interval from "|" to "|" represents one bar in the reference origin chord chart data 100a, so that a CPU reads letter string data therebetween and sequentially generates chord information (generation timing, a chord route, and a chord type) for each bar on the basis of the read letter string. Rhythm information acquired, and stored in an RAM is used for generating the "generation timing". The rhythm information is not included in the reference origin chord chart data 100a so as to be set independently of the reference origin chord chart data 100a. When generation of the chord information for each bar is performed till the last bar, the chord progression information is generated.SELECTED DRAWING: Figure 2
