The song "Ennai Thalaatta Varuvaalo" from "Kadhalukku Mariyadhai" is a very popular song by Ilaiyaraaja. Recently there was a song "Oru porkaalam thodangum" from the film "Kasthurimaan" again by Ilaiyaraaja. I could sense a similarity in the opening lines between the two songs. The tune looks somewhat similar. However the similarity ends after the first 2 lines. So I mixed the 2 songs together. Listen to this below. In the middle, you will notice that both the songs are played simultaneously with one song on the left and the other song on the right.
Speaking of "Ennai Thalaatta Varuvaalo", the other version of this song from the same film is "Idhu Sangeetha Thirunaalo". Both these songs are set in 4/4 adhi thalam. The song is predominantly in the scale of the keeravani ragam, I believe. Now listen to the prelude of the "Idhu Sangeetha Thirunaalo" song below.
When I listened to the above prelude, it seemed that the timing was in 3/4, but again it was not matching completely in 3/4. Then I heard a few more times and found that the timing goes as follows:
1 2 3 | 1 2 3 | 1 2 3 | 1 2 3 | 1 2 3 4 ||
1 2 3 | 1 2 3 | 1 2 3 | 1 2 3 | 1 2 3 4 ||
tha ki ta | tha ki ta | tha ki ta | tha ki ta | tha ka thi mi ||
tha ki ta | tha ki ta | tha ki ta | tha ki ta | tha ka thi mi ||
Each cycle comes to a total of 16 counts there by effortlessly maintaining or switching to the 4/4 beat after this initial piece. Again the actual beat is predominantly 1 2 3 | 1 2 3 | 1 2 || which is 8 counts.
The 16 beat count above is also used in the song "Siriya paravai siragai virithu" from the film "
Antha Oru Nimidam" however in a much faster tempo. You will notice that the tune also fits into this timing. This is however used only for the 1st 2 lines.
Speaking of the Siriya paravai song, refer
this article to know how IR has used Shruthibedam in this song, where he changes to Charukesi in the 2nd interlude and the following stanza.
