Do you remember the dhun played by Amitabh Bachhan on mouth organ in SHOLAY when he used to look at Jaya Bhaduri? Do you know these very notes were used to make song 'Aane wala pal jane wala hai' (Golmaal: RD Burman, ), now compare that song with opening notes of Yaro sun lo dil ki (Rok sako to rok lo: Jatin Lalit), do they sound similar?.... because they are all based on raag Kirvani.
we all agree that there is nothihg wrong in rag based compositions.
but that does not mean that they are copies at all though they may sound similar.
there are a finite # of factors which influence a MD when he/she is
composing a song.
1. his own knowledge and exposure to different kinds of music,
2.public taste
3. the demands of the filmmaker.
So for example HR is a young guy in his early 30's so he has been exposed to a whole body of Hindi music (SDB, RDB, LP, OP, etc...) not to mention western music and of course Pakistani and Arabic music.
So naturally, these influences will show up at various times in his music. I think that sometimes a composer does not even realize where his inspiration is coming from when he is writing music. Now with the internet, it is easy for people to root these things out. But
in the old days when a song seemed heavily influenced by a genre, I don't know if there was such protest. I know that a lot of Bengali composers were influenced by Tagore as well as baul music. Sometimes old Tamil songs sounded like Salil chowdhury songs or maybe vice versa.
I would love to know of what other members think in this regard: how do you define plagiariam, raaga & folk song based influence so on.
