A sruti is the interval between two audibly different pitches in Indian music. Thus, if a given note is to be taken somewhat lower or higher than usual, a teacher will often instruct her student to sing it "a sruti higher" or "a sruti lower." It does not refer to a specific ratio (e.g. a half-step), but rather to a psychoacoustic difference. Treatises from the first millennium report that the octave used to be divided theoretically into 22 sruti-s, and at that time, intervals seem to have been measured precisely in srutis. By the 16th century, however, this practice seems to have died out, except in popular folklore.
