The Rāgas of Indian Music have their origin in folk melodies of different parts of the country
and are being performed and practiced by independent ethnic groups. More delving deep into
this matter indicates the unique characteristics of folk forms, engendered by man's
spontaneous habit of cultural expression apart from their continental contrast. Because of
this coherence, outside of the Indian subcontinent, a close resemblance is very observable
between Indian Rāgas and foreign Modes. Undoubtedly these Modes are also generated from
the folk tunes of those lands as in Rāgas. In this article, an attempt has been made to establish
this kind of cultural integrity and singularity by analyzing three traditional Japanese Scales,
which carry tonal similarities with the three North Indian Rāgas.
