Probablity and the seven swaras
Are you one of those people who ``chose'' to take physical education
in 11th standard with the apparent excuse that it was more related to what
you wanted to be, and math wasn't? Well, if you are, then you are in the
right place right now. I'm glad you are finally here.
Because here's where you find out why math is important.
Because if you had taken math in 11th standard, you would have learnt
some basic stuff about probability and chance. To quote Bob Marley, then
you won't have to ask me, just who the hell do I think I am?
What am I talking about? Yeah, well it usually takes me some time to get to the point. But hey, by clicking on the timepass pages you agreed that you were here to waste time anyways, right?
Before I spew some venom, let me review basic probability for you: suppose
you have a set of five blanks, like so:
_____ _____ _____
_____ _____
and I asked you to fill each blank with a number between 0 and 9. The
question is, what is the probability that you end up with the number 12345
(or any other number, it doesn't matter)? The answer: consider each blank
separately. There are 10 numbers to choose from, so the probability that
you choose one of them is 1/10. The probability therefore, that you fill
the first blank with a 1, is 1/10. The probability that you fill the second
blank with 2 is also 1/10, and so on. But the chance that you fill the
five blanks IN ORDER with 1, 2, 3, 4 and 5 is then
0.1 X 0.1 X 0.1 X 0.1 X 0.1, which is 0.00001, or one chance in a hundred
thousand. Do you think this event is probable? You do? Okay. Consider
this. Consider this, hint of the century, consider this script.
Suppose you and another friend of yours are given two separate sets of five blanks each, and are asked to come up with a five digit number, what is the probability that you both come up with the same number (if there was no ``collaboration'' between the two of you)? The answer: 0.00001 X 0.00001, which is one chance in TEN BILLION. Think that is probable?
Where am I going with this? Be patient, I'm almost there.
So, this is what I was talking about to a Tam friend of mine, quite a few years ago, and this is just a typical conversation, because I remember this subject coming up again and again (I never keep quiet about these things, you know), and the answer being the same:
Me: Shit! This song is copied from an English song! How can you
even think this ``composer'' is original???
Friend: Of course he is original! How do you know he copied
it from that song? You are so biased!
Me: Well, its copied because the leads are exactly the same!
Friend (eyes thinned into slits, since I have insulted the very
existence of the Tam being): Dey, ezhu soram daan irukku da, overlap
aaha daan aahum (translation: Hey, there ARE only seven swaras
(notes) in music, there WILL be overlaps)!
Some names might have been censored (including the name of this ``creator, not imitator'' Tam ripoff ``musician'') in the above dialogue.
So what, you say? How many of you believe this shit? Do you really think, ``Of course! There ARE only seven notes in music, there HAVE to be two people who think up the exact same progression!''??? If yes, then I'm glad you are here. Here's a simple calculation in probability that can help prove it to all you mofo's finally that I speaketh the truth:
Let us consider (without loss of generality) the song, Tarzan
Boy by Baltimora. The chorus to which goes,
``Oh oh
oh oh oh
oh oh oh
oh oh oh
oh'' (where the colours signify different
notes) There are 12 oh's in this chorus. Now, consider the song
Tum Ladki Ho from Maine Pyar Kiya. Let us consider
the possibility that the tune to this song was not ``inspired'' by the
former song, but the fact that the chorus sounds exactly the same is just
because of the fact that there are only seven notes (``Dey! Ezhu
soranga daan irukuu, na!''). The chorus to this song goes (in
the ``melodious'' voice of SPB):
Hey hey hey
hey hey hey
hey hey hey
hey ho ho....
Think of it as 12 blanks, each of which can be filled with one of the seven sorangal. Since each note is equally likely, there are 7 possibilities for each blank. Therefore, the probability that ONE particular arrangement of notes - namely, Baltimora's Tarzan Boy arrangement - accidentally turns up when Ram-Laxman were trying to think of a tune for Tum Ladki Ho, is 1/7 X 1/7 X.... twelve times... that is 1/712 , which is close to one chance in TEN BILLION!!!!
Still think it's all just because of there being
only ezhu sorangal?
