Nice one Gowtham. Many chords seem right to me. Their placement could be more precise though. There are only a few basic chords used in the song.
The song's magic is all credit to Ilayaraja's amazing tune, bass track, arpeggios and of course, Jeyachandran's voice! Original scale seems to be Eb (according to youtube).
(Eb)Uravu(G#)gal (G#)thodar ka(Eb)thai (Eb)unarvu(G#)gal (G#)siru ka(Eb)thai
(Eb)Oru kathai yendrum mudiyalam
(Eb)Mudivilum ondru thodaralaam
(Eb)Un nenji(Gm)le (Eb)baaram unakaga(Gm)ve (Eb)naanum
(Eb)Sumai thaangi(G#)yaai thaanguven
(Eb)Un kanga(Gm)lin (Eb)ooram yedarkaga(Gm)vo (Eb)eeram
(Eb)Kaneerai (G#)naan maatruven
(G#)Vedanai theeralam(Bb) verum pani(G#)ii..vilaga(Bb)lam
(Cm)Venmegame puthu azhagile naanum inayalaam
Will try and post interludes sometime later.
