ABSTRACT:
The present chord progression composer provides an open and wide space of composition and yet can compose those chord progressions having a desired valuation of fitness for a given melody. To this end, the composer receives an initial chord progression population. It computes melody fitness valuation of chord progression individuals of the population of interest. The chord progression population repeatedly undergo genetic operations (selection, crossover, mutation etc.). The melody fitness valuation will generally increase with generations under the control of the chord progression composer.
