Here is my personal journey with this kriti..perhaps there are more analytical studies out there - but here goes..
This magnificent composition by Muthuswami Dikshitar is very complex in the amount of musicality packed into it. the notes seem simple at first, until you start digging into how each raga is played out. It was a truly memorable experience to learn it. There are at least 2 versions being practised. One version is sung by MLV and others, where certain embellishments are introduced in each raga, especially the Vilamba-kala portions of the song. The second version is from Musiri Subramani Iyer and eliminates all this - in fact my veena guru Mrs Lalitha Venkatraman explicity said "all that detracts from the main kriti, so no need to do it".
Now the piece itself. It refers to 14 'bhuvanas' or worlds that have taken the form of these 14 ragas and are offered as a garland to Siva or Vishwanatha.
The 14 ragas are not split as half: 7+7 . Instead, the structure is:
Pallavi (2), Anupallavi (4), Viloma(reverse), Charana (8), Viloma(reverse).
Each of the 14 ragas has Vilamba-kala phrase followed by Madhyama-kala phrase.
This itself is remarkable, but even more so, see below.
Number of avartanas:
Anupallavi: 4 ragas total: 2 ragas * 2 + 2 ragas * 1.5 = 7
Charana: 8 ragas total: 4 ragas * 2 + 4 ragas * 1.5 = 14
(why did he choose 1.5 avartanas to the latter portions? is it just to reach some factor of 7 ?)
Finally, it is remarkable how the composer can bring out key raga lakshana in half-avartanas only! The pauses and word selections - all done with purpose (and inspiration).
The ease of transition between ragas is also so amazing.
I really enjoy playing this on the veena - pretty sure Dikshitar did as well !!
I welcome all inputs and comments, especially on things i got wrong!
