The Construction, Reconstruction, and Deconstruction of Shruti

2010, Hindustani music: thirteenth to twentieth centuries Bor, Joep, New Delhi, Manohar

Abstract

Intonation, and in particular the concept of shruti, has perhaps received more scholarly attention than any other topic in Indian art music. After the Natyasastra, the first work to discuss shrutis extensively, virtually all treatises on music have elaborated, criticized or commented upon this issue. Shruti is intimately linked to the fundamental concept of svara. Whereas svara is a musical note or scale degree, shruti is a more subtle division of the octave. From early times, an octave was said to contain twenty-two shrutis, and as we shall see, the relation between shruti and svara has been a major source of confusion. It has not been uncommon to refer to shrutis as microtones or quarter tones, but with twenty-two shrutis to divide over seven svara in an octave, this clearly presents a mathematical problem.
