  The works of Rabindranath Tagore have been sung by various artistes over
generations spanning over almost 100 years. there are few songs which were
popular in the early years and have been able to retain their popularity over
the years while some others have faded away. In this study we look to find cues
for the singing style of these songs which have kept them alive for all these
years. For this we took 3 min clip of four Tagore songs which have been sung by
five generation of artistes over 100 years and analyze them with the help of
latest nonlinear techniques Multifractal Detrended Fluctuation Analysis
(MFDFA). The multifractal spectral width is a manifestation of the inherent
complexity of the signal and may prove to be an important parameter to identify
the singing style of particular generation of singers and how this style varies
over different generations. The results are discussed in detail.
