Manna Dey, legendary singer, dies at 94

I may not know music but have sense for music and Google:

1. The absolute frequency of a female voice is about twice the
absolute frequency of a male voice. Therefore, when Lata and Rafi are
singing together, Rafi is singing the (lower) octave equivalent of
what Lata is singing.
2. While male singers can (and do) employ head voice to sing high
notes, in the context of playback singing, the loss of “masculinity”
that accompanies transition into head voice is probably the reason
most singers prefer to “belt out” their mixed register as high chest
notes. While comparing voice ranges of male singers, therefore, it
makes sense to consider only their chest voice.
3. Finding the range of a voice and classifying a voice as being of a
certain type (depending upon vocal range) are two completely different
exercises. The former involves finding the highest and lowest note
produced by the voice while the latter involves finding the most
comfortable range, or tessitura of the voice. For example, a soprano
and a mezzo-soprano may have similar vocal range, but the former will
have a higher tessitura with a stronger head register.
4. Male voices are classified into four types: tenor (C3 – C5),
baritone (F2 – F4) and bass (E2 – E4).

Let’s start at the bottom of the list. Basses are difficult to come
by. Can’t think of any as far as Hindi films are concerned. KL Saigal
came close. He went down to (I think) E2 in ‘do naina matwaare’, and
he was comfortable alright.

Baritone is the most common voice type. All the leading playback
singers – Rafi, Kishore, Talat, Mukesh et al – were baritones with
varying tessituras. I am familiar with Rafi’s, and to some extent,
Kishore’s output, so I’ll talk about them a little.

Rafi was a high baritone. Many of his songs go as high as A4, some
even up to B4! For example, ‘dole re dole re praan’ and ‘dekhi zamaane
ki yaari’ (the highest note is in head voice, though). The lowest I
can recall is ‘tune mera yaar’ in which he went down to Bb2
(incidentally, in the same song, he also attempted to hit Bb4 two
octaves above Bb2, but cracked on it!)

Kishore’s highest note should be around F#4 – ‘beqaraar dil tu’ or
‘koi hota jisko apna’. In the second song, he also goes down to A2
(which makes his recorded range over one and a half octave). He
deployed his falsetto voice to sing in the female range in ‘aake
seedhi lagi’, going as high as G#5 – more than an octave above his
highest chest note! I think the tonic was C# for that song, and on
that scale, G#5 would be his *ati-taar* pancham (whereas it would have
been taar pancham for Lata).

Manna Dey was also a high baritone. His highest recorded note should
be Bb4 – ‘ketaki gulaab juhi’, ‘ek ritu aaye’ and ‘ud ja bhanwar’. In
the third song, he also goes down to Bb2 (I think), which makes his
recorded range over two octaves.

Coming to the highest voice type – tenor – I can only think of Nusrat
Fateh Ali Khan at the moment. He routinely did C5 in chest voice, and
I’ve heard him go up to D5, which is insanely high! Oh, his nephew,
Rahat has an extremely high range too. There are several B4’s and even
C#5’s in ‘ajj din chadeya’.

Are you trying to suggest you know more about music than music directors of that time?
