Abstract
First, an extracting unit extracts chord progression of a tune to be reproduced. Then, a timing detector detects the timing of variation of the chord progression extracted by the extracting unit. Subsequently, an add-tone reproducing unit combines an add-tone with the tune to be reproduced according to the timing detected by the timing detector. The add-tone reproducing unit can also move a sound image to reproduce the tune or reproduce the tune as an arpeggio.
