BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music composition technique, and more particularly, to a music composition support device capable of automatically composing music by combining a coarse sound and a discordant sound in accordance with a music fragment input by a user.

Mars is the temporal flow of sound produced by successive chords in music. The study of the method of continuing the harmonics is called the harmonic law or harmony. A chord is a note that occurs when notes of different pitches sound at the same time. When two or more notes are sounded at the same time, some notes sound good to hear and some notes feel inconvenient to hear. The notes that sound good for listening are called "coarse" and the notes that are uncomfortable to hear are called "dissonant".

Generally, the number of chords used in one melody line is about three or four, and the key chord that is the most basic when making a harmonic is called a tonic. The harmonics that make Mars the best match with the master chord are the dominant and the subdominant.
