I must never get any heart ailments in my life time, if pundits are true! Yes, Keeravani raga is supposed to be good for heart and Raaja has given us innumerable Keeravani based songs. The more and more you pay attention to the nuances how Keeravani raga has been handled by Raaja, I really wonder, if anything in Keeravani is left unexplored!!
But, the Keeravani based numbers aren't stopping. Even recently in Uliyin Osai, Raaja gave some good piece in Keeravani. Here is the scale for Keeravani: S R2 G2 M1 P D1 N3
Clearly, there aren't any dissonant notes (vivadhi swaras). A perfect scale for melody. If an various permutation combinations of these notes were tried using an algorithm, you might cover pretty much a big spectrum of Raaja's Keeravani based songs.
Some of the famous Keeravani based songs in Illayaraja's composition are:
Kaatril Endhan Geetham (Johnny)
Un Kuthamma En Kuthamma (Azhagi)
Unna Nenaichaen Paattu Padichaen (Apoorva Sagotharargal)
Nila Adhu Vaanathu Mele (Nayakan)
Keeravaani Keeravaani (Paadum Paravaigal)
Ennulle Ennulle (Valli)
Povoma Oorkogalam (Chinna Thambi)
Ennai Thaalaatta Varuvaalo (
Kaalathai Vendra Kalaignan (Uliyin Osai)
The key thing to note here is how Illayaraja has used Keeravani in a wide array of situations. Starting from a "Ekkam" to "Sogam" to "Romantic" to "Dappanguthu" - has used the same Raaga. In some cases, he has taken advantage of his orchestration skills to use the same tune both in a happy and sorrow situation in the same movie.
For instance, "Povoma Oorvolam" from Chinna Thambi re-appears in the climax as "Nee Enge Naan Inge" with the same tune based on same raaga, but with a complete different orchestration. Thanks to Keeravani that is flexible and doesn't pose a stiff challenge, unlike other Raagas.
Let us deal with Keeravani more in my subsequent posts.
