MUSIC COMPOSITION REPRODUCING DEVICE AND MUSIC COMPOSITION REPRODUCING METHOD
摘要
<p>Firstly, an extraction unit (101) extracts a chord advance of a music composition to be reproduced. Next, a timing detection unit (102) detects a timing when the chord advance extracted by the extraction unit (101) changes. Next, an additional sound reproduction unit (103) adds the additional sound to the music sound at the timing detected by the timing detection unit (102) and reproduces it. The additional sound reproduction unit (103) can move a sound image for reproduction or perform reproduction as a broken chord.</p>
