Abstract
Bar codes representing sound information are printed on a marginal portion of a score. Prior to the performance, these bar codes are read out by a bar code reader, whereby chord data represented by these bar codes are successively stored in a memory provided in the body of a musical instrument. At the time of the performance, accompaniment sound corresponding to the stored chord data is automatically added to the melody performed by the player.
