Ramesh / VK: Having been a witness to Smt. Sowmya's research work and its outcome (mostly as a helping hand, nothing more!), I must say that the innocuous-sounding title of the thesis masks what will eventually be acknowledged as a path-breaking PRACTICAL innovation to stabilize the pitch of the instrument, which varies widely across climatic variations and ambient conditions, posing a challenge to performers especially in this age of globe-trotting! Importantly, this has been done WITHOUT tampering with the basic construction or natural materials traditionally used in constructing the mridangam. Professional percussionists and mridangam craftsmen have been involved in the work. I believe the thesis can be made public only after the convocation, with the University's formal consent. As of now, the results have been publicized only at her final viva voce that happened on Sept. 4th, wherein the examiners recommended that Sowmya be conferred with the Ph.D.
