I was trying to play "Kanmani Nee vara Kaathiruntaen" song from "Thendralae Ennai Thodu" in my keyboard.
I know the combinations of music.. like S R1 G1 M1 P D1 N1 S and I know there are 3 Rs 3 Gs 2 Ms 3 Ds and 3 Ns and their positions in my keyboard.
So I figured out this song belongs to the category S R1 G3 M1 P D2 N2 S. The first 4 scales were similar to Maya malawa gowla. So I went to http://www.carnatic.com/carnatic/ragalist.htm and understood that this scale belonged to the 16th mela kartha raagam and it is called as Chakravagam.
Then I went and googled for the raga of this song to confirm that this song belong to Chakravagam category. In a yahoo discussion group, I found that they were talking about this song belonging to MalayaMarutham category. So I went deep in the site and found the scale for MalayaMarutham raga and found the M is missing. So the scale is S R1 G3 P D2 N2 S and it fitted well. So learnt two raagas today. One is Chakravagam and another is Malayamarutham.
A few songs that belong in Malayamarutham raaga is
Kanmani Nee vara kaathiruntaen from Thendralae ennai thodu
Ragasiyamaai Ragasiyamaai from Dum Dum Dum
Kodi Inbam from Nenjil Aadum Poo Onru (today only I heard this song)
If I figure out some more songs, I will add it to the list when I come across.
