Here are the qualities that make NCK the winner in the history of all such shows:
1) Total command of words and intonations.
2) Incredible memory for lyrics.
3) Total comfort with fast changing scales and lyrics.
4) Great breath control, even after dancing and jumping during the song.
5) Ability to emote and act during the song without compromising singing.
6) Ability to maintain sur througout the song (probably the most important).
7) Great imagination to add individual touches to songs; so as to not imitate the original version. (Hema is even better at this)
7) Knowledge of the fundamentals of music, sur, taal etc.
8) Voice quality. Incredibly smooth, without jitter. A little high pitched for my taste. But, can change voice to suit song (eg. yamma, yamma song).
All of this at the young age of 19, with experience to gain, is just an awe-insipiring combination. Good luck NCK!
PS. If any of the above goes over your head; seek the nearest parent/elder for explaination. 😉😉
