摘要： The present invention provides method and system for composing music with chord accompaniment. One or more keys on a first keyboard are selected by end-users to generate a chord progression, and a computer generates a chord progression MIDI file, and associates the file with a first physical card that is embedded with a unique machine-readable ID (UID). After the UID of the first physical card is subsequently recognized, the chord progression MIDI file is retrieved and played. While the chord progression MIDI file is played, certain keys on a second keyboard are highlighted, and each of the highlighted keys on a second keyboard represents a music note that is in harmony with a particular chord in the chord progression while the particular chord is being played, and one or more of the highlighted keys on the second keyboard are selected by the end-user to compose a melody.
