The earliest sprout of Brahmanism classical music can be seen in Nateya Shastola. Na Teia Shastola will take the smallest differential interval obtained by hearing as "Shruti" (meaning "hearing" in Sanskrit), and usually divide an octave into 22 shrutis. In actual music, two or four shrugs are regarded as an interval (called "Svahla"). Svahla and interval also mean pitch. It consists of seven Svahla in octave, and its scale is called sarigamapadhani.
