ABSTRACT:
In a musical instrument having a solo and accompaniment keyboard apparatus is provided whereby an accompaniment tone color is selected which adaptively complements selected solo tones. The first zero crossing spacing of the autocorrelation function for the solo tone is used to implement a tone selection logic. An effective zero crossing is computed for combinations of available accompaniment tones. An accompaniment tone combination is selected whose effective zero crossing has a maximum value that does not exceed a complemented value of the zero crossing for the selected solo tone.
