China also passed on to Japan the ceremonial dances of India with their music, which were Japanized as the solemn and colorful Bugaku. - Curt Sachs

[And here is what Sachs has to say about the 7-tone-22-shruti system of notes described in Bharata's text:] We know that two basic principles have shaped scales all over the world: the cyclic principle with its equal whole tones of 204 and semitones of 90 Cents, and the divisive principle with major whole tones of 204, minor whole tones of 182, and large semitones of 112 Cents. Bharata’s system derives from the divisive principle, and this, in turn, stems from stopped strings. But the earlier part of Indian antiquity had no stringed instrument except the open-stringed harp; no lute, no zither provided a fingerboard. India must have had the up-and-down principle, and it cannot but be hiding somewhere.

[In Siamese (Thai) music,] "the comparatively large share of drums, however, indicates the neighborhood of India"

The strange, never-ceasing drones used in the choral singing of Tibet belong in the Indian, not the Chinese sphere of Tibetan civilization.
