I have always failed to understand this allergy of masses to the instrumental components of a song.
There have been many compositions by RD Burman, AR Rehman which have very powerful instrumental interludes & preludes. In particular Pancham was a very good user of instruments, we have seen this in songs like tere bina jiya jaye na(Ghar) whre he has played chords on tabla tarang or complicated use of wind instruments in unknown films like Drohi/Samundar etc. His preludes & interludes have so much to discover in terms of instrumental expertise that any ardent instrumentalist will never get tired of listening to his songs. If some of these effects like the one I mentioned about tere bina jiya jaye na, got recognition then it is because these effects supported the vocals in a subtle way in form of tala. If this effect was introduced in an interlude then needless to say it would have got consigned to oblivion.
I read somewhere that slightly metallic effect of 12 strings guitar in the prelude of Ha yahi pyar hai(Rocky) is because Pancham converted 12 strings into an electric guitar….!
Now going by the discussions all around I can safely assume that many such beautiful works by different composers have gone unnoticed by listeners.
And this soutela treatment to the instrumental components continues even today, I often wonder how composers like ARR must be feeling when their predominant instrumental compositions like title track of thiruda thiruda goes unnoticed.
This is a big reason why RDB's work of 80s has gone unheard by & large, these were the years when he extensively experimented with miscell. instruments & effects.
I'm afraid to admit that quite a chunk of this allergy has been propagated by Golden era lovers, I being one of them.
Somehow this concept has grown all these years that a song must be judged by its lyrics/sur/expression/flow & other things, instrumental support being the last of it.
