Ravi, since my review of Sudha's concert wasn't overly positive, I used the mOhiniATTam as counterbalance! Now I see what has happened! I'm so sorry for sounding stupid, but what is sOpAnam?
The music for mOhiniATTam is called sOpAnam music - unfortunately, it sounds just like CM to me, sung in ati-vilamba kAlam. I am sure someone with your technical skills will be able to notice differences, and I was hoping to be educated!
