Abstract
A plastic card mounting an IC memory of a credit card size called a music card stores encoded digital music information including tone, musical interval, musical length and loudness of each musical note and pause, and said music information actuates a synthesizer which generates music sound signal. The music card also stores a character code for indicating title of music on said synthesizer. As music note is encoded and stored in a digital form, a small capacity of IC memory is enough for storing a long play music.
