Remember Nihira's 2 octave singing of Hare Rama Hare Krishna.??
Is singing at 2 octaves difficult, my 2 cents:
while 2 octave singing needs a good range control, It can be more difficult to sing a song with various crescendos: rising tempo & hitting low........without a time frame, latter needs very good breath control & superb modulation. In fact most of the imes it would be more difficult to sing latter than former.
Rangeela re was more difficult than HRHK, but somehow, latter got hyped more. While Nihira is flawless in most of the songs in terms of both range control & voice modulation, Himani's Kache dhaage was also quite good in this respect. There are other singers also who have this capability & need appreciation.
Hema is master of this art..I've seen him doing this quite a few times.
Credit also goes to ID who has consistently guided her in song selection very well.
