1. Sruti in Ancient, Medieval and Modern Contexts   by Dr.N.Ramanathan, Head, Department of Music, Madras University, Chennai on Sruthis. This article puts the entire subject in proper perspective and is a refreshing departure from the practice of assigning frequencies to the 22 sruthis (in my view, without adequate analytical evidence on present day music) The article was first published under the title "SRUTI-S ACCORDING TO ANCIENT TEXTS" in the Journal of the Indian Musicological Society, Baroda. Sept. & Dec.1981, Vol.12, No.s 3&4, pp.31-37. It was later revised and presented as a paper at seminar under the title "SRUTI - ITS UNDERSTANDING IN THE ANCIENT, MEDIEVAL AND MODERN PERIODS" in the National Seminar on Perpetuation and Preservation of Indian Classical Music, Historical Continuity
