He has used this style in all genres of songs. Ending the charanam with pallavi's tune and again reverting back to pallavi. This style of composing MSV started way back in 50s itself. "Othayile Athamaga Unna nenachi Rasicha Maaga, Kannu rendum moodalaye kaala neram koodalaye". And finally, listen to the last two lines of the charanam. You can find similar style of usage in the song "Azhagiya Tamizh magal". And also in the lines ""Unnai Enni naane, Ullam Vaadi Ponen" the gamakams at the end is also MSV"s style. R.Sundarrajan mentioned in an interview that Ilayaraja himself wanted to get all the tunes from MSV as he wish and Raaja asked R.Sundaraajan not to meddle in composing. Ilayaraja must have specifically asked for this kind of compositions. For example: Naalai Indha Vellai(In the line Vana Vizhiyin vasalail), Bharathi Kannamma(In the line megangalil kaanum padam), Naalam Naalam thirunaalam (in the pallavi). This exact same change he has shown in numerous songs from late 60s to late 70s. In the charanam, he has used N3 in the first line (N3SR SRSN3S) and in the third line he has used N2 (DN2S N2SN2DN2). For example: In "Anubhavam Pudhuamai", he touches the Da1 exactly like this. This is something MSV has done in so many songs. Swaras for the line "Oodha Kaathum Adichiruchu" is G3PG3 G3R2S PD1. He has followed the same in this song too. MSV rarely stick to scale or Raaga unlike other composers.
You people should listen to his songs before blabbering. Those who have commented MSV has never done such tunes have lack of knowledge in his music. This tune is typical MSV's style of tune. This kind of arrangement is unique and we can only find it in Raja sir's music.
For example - Pani Vizhum Iravu from Mouna Raagam. We can find the similar use of instruments in many of his Night-songs. The way he has used flute and synthesizers to give the night effect is brilliant. Raja's chord progression adds beauty to this melody. This has got both MSV and Ilayaraja's style. This is what we get when two legendary composers join hands together.
