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

[In respect of the Slendro or "male" scale in Indonesian music,] "It seems that the modes or, better, the melodies ascribed to the modes, matter today only from the standpoint of choosing the adequate time for performance: pieces in nem are to be played between seven and midnight; sanga is the right mode for the early morning between midnight and three and for the afternoon between noon and seven; manjura belongs to the hours between 3:00 A.M. and noon. This time table is unmistakably Indian. The name salendro points also to India. It probably stemmed from the Sumatran Salendra Dynasty, which ruled Java almost to the end of the first thousand years A.D. and had come from the Coromandel Coast in South India. Thus it might be wiser to connect slendro with ragas like madhyamāvati, mohana, or hamsadhvanī than with the Chinese scale"

In the retinue of Buddhism, it had a decisive part in forming the musical style of the East, of China, Korea and Japan, and with Hindu settlers it penetrated what today is called Indo-China and the Malay Archipelago. There was a westbound exportation too. The fact, of little importance in itself, that an Indian was credited with having beaten the drum in Mohammed's military expeditions might at least be taken for a symbol of Indian influence on Islamic music. Although complete ignorance of ancient Iranian music forces us into conservation we are allowed to say that the system of melodic and rhythmic patterns characteristic of the Persian, Turkish and Arabian world, had existed in India as the rāgas and tālas more than a thousand years before it appeared in the sources of the Mohammedan Orient.

When we read in Bharata's classical book of the twenty-two microtones in ancient Indian octaves, of innumerable scales and modes, and of seventeen melodic patterns and their pentatonic and hexatonic alterations, we realize that music at, or even before, the beginning of the first century AD was by no means archaic. Indeed, there is no reason to believe that India's ancient music differed substantially from her modern music.
