 A scale with 25, 35 or even more pitches can be obtained by combining these base ratios, as in five-limit tuning.In Indian music, the just diatonic scale described above is used, though there are different possibilities, for instance for the sixth pitch ("Dha"), and further modifications may be made to all pitches excepting "Sa" and "Pa".Some accounts of Indian intonation system cite a given 22 Shrutis.
