I read in Hindu sometime back that Apollo Hospitals, Chennai has a music therapy center. A call-center employee had recurring migraines and associated health problems. She was asked to listen to the Raga Mohanam 6 times a day whenever she felt a migraine come on. The lady reported 4 months down the line that she rarely ever had headaches now!
I was feeling super-stressed this morning. For lack of anything else to distract me, I started playing a Ragam Tanam Pallavi in Mohanam by TV Sankaranarayanan. I can swear that the moment I heard the initial notes of Mohanam, I could feel the stress draining out of me, literally. My neck muscles loosened up and I was feeling much more peaceful in a few minutes.
I have felt that hard-core music enthusiasts discount Mohanam as a Ragam. They extol the virtues of Bhairavi, Todi, Kharaharapriya et al. because of the scope offered for manodharma. But if you ask me, I'll take a beautifully sung Mohanam over any other Raga in Carnatic music! :)
