PROBLEM TO BE SOLVED: To solve the problems that, while a melody road can be formed only for a musical piece that can be expressed by a scale playable with a normal musical instrument and the sound of upper and lower chromatic scales can be determined by multiplying or dividing the frequency of a fundamental tone by a coefficient of about 0.934 for the determination of the scale in a conventional technique, it is extremely difficult to use and apply the voice of a person, the cry of an animal and a musical piece that cannot be expressed by notes of staff notation in a conventional music technique such as ethnic music and a musical piece peculiar to a region in which the pitch of the sound freely changes, etc., to a melody road or a road that plays music.SOLUTION: By converting the change of the frequency of the sound to be used for the melody road at every foundation unit frequency generation groove interval as needed, the voice of a person, the cry of an animal, and sound expressed by freely changing the pitch, volume and tone of the sound by the natural change of the frequency that cannot be expressed just by regular and stepwise scale change in music can be used in the melody road.
