I am learning Carnatic Classical Music (well, I used to learn for a long time, and will restart learning in the near future), and for me, Music is something that links human with God. Almost all the kritis and varNas sung are known both for their sangIta aspect and the sAhitya aspect. Then, why pray, are they sung with such a horrible accents that one cannot even figure out the lyrics, let alone enjoy them? With the exception of a few, musicians do not even *try* to pronounce words properly. For some time, I had completely stopped listening to vocalists because their mistakes were so glaring that I could not even appreciate the good parts in their music!
An example- an old CD of GNB's recordings had this in its index "Manasulonima" ... ! Is it so hard to figure out that it 'manasulOni' and 'marmamu' are two different words? I have heard a musician pronounce 'nArada bhayahara' as 'nArada bayagara'. 'One who dispelled the fears of nArada' became, to my Tamil-untrained ear 'One who created fear in nArada'!
I had once attended a concert of T.N. Seshagopalan, one of my favourite musicians. He sang a romantic aShTapadi in - tODi! The rAga tODi is good for dainyarasa, and certainly anything but romantic! His Todi is impeccable; I have not listened to any tODi better than his. But it would have been much more enjoyable if he had chosen a different composition, or sang the same aShTapadi in a different raaga like kAmavardhini!
A course in saahitya must be made mandatory for musicians. This will help them put more emotion or bhAva into their singing. For example, lines like "kaantamagu pEru ponditivi" in "paalinchu kaamaakShi" are filled with love and devotion for the Mother. The neraval should bring out this devotion and love. It is of no use otherwise. I have heard some 'good' musicians sing 'nagumOmu ganalEni' with an enthusiasm that puts an child high on espresso to shame ! The meaning of the pallavi of this kriti is 'Rama, how can you have a smiling face when you know about my suffering?' See what happens when the musician does not understand the lyrics? It is the confluence of sAhitya and sangIta that makes Carnatic music so beautiful. Unless musicians understand this, they cannot do justice to their music.
