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

The oldest preserved style, the classical Sino-Japanese Bugaku dances […are…] of Indian origin, and Chinese and Japanese music on the whole were under Indian influence in the second half of the first millennium A.D. And yet the most typical trait of Indian music, its sophisticated rhythmical patterns or tālas, had no chance in the East. In 860 A.D., someone wrote a treatise on drumming in China, with over one hundred ‘symphonies’ which doubtless were Indian tālas; but nothing came of this, and not one of the Far Eastern styles has preserved the slightest trace of such patterns. The three rhythms used in Tibetan orchestras, and kept up in percussion even when the other parts are silent, are obviously not Far Eastern, but deteriorated Indian patterns. The elaborate polyrhythm of Balinese cymbal players that Mr. Colin MePhee has recently described is not Far Eastern either.

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

[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.
