AR has a strong presence in melody like his predecessor IR. What makes him different and appealing to the current trend is the way the melodies are arranged along with orchestration. Well IR also has as well done this but the difference is voice and instruments contributing melody together. IR songs has orchestration in interludes and then followed by the voices. Listen to Hawa sun Hawa from ADA (leave aside the topic why the reels are still secure in the box) The first interlude begins with the flute and sets it all when singing continues to take it further. From there the entire song just follows and its pretty difficult to guess the phase. Clearly different from other MD's melody. A melody song either from HJ or Yuvan has either a strong section of singing or the orchestration and if together the melody of orchestration is played and stops with interlude and theres a distinct separation before the voice. Coming back to AR listen to Kannamucchi yennada (KK), Sonnalum (KV), yenthan vaanil (KV), Kandukondein Kondukondein (KK), Azhage Sugama (Parthale Paravasm), E Ajnabi (DilSe), Hosanna (VTV).. the list goes on. This is one such among the various techniques used by AR which clearly sets him apart from the race of other MD. I shall try to write how AR is unique in using harmonies sometimes in my next post. But need to learn more before I write
