The maths in Melakartas and writing IF-THEN without writing IF-THEN

Jan 24, 2005 23:43

Note: this is more of a maths/computing post than a music related post.

To give a brief introduction: there are 72 different primary ragas or parent ragas (loosely you can call them as 'scales') that are nothing but the permutation and combination of the various notes that can appear in a scale (again they follow the rules -- see link). These 72 ( Read more... )

Nice to know. I'm no big musician or whatever. I'm just learning and into it for ~3 months now. but I *love* it entirely. :)

I've added you as my LJ friend.

on the guitar right? ive tried playing veena on a guitar but it was unsuccessful.

what songs do u know? have you dont any keerthanams? i just started krithis last august. ive only learned 6, my teacher keeps alternative from krithi to varnam. i like the familiar organization of varnums, the pallavi, anupallavi, etc. My teacher was a disciple of the late Chitti babu. have you heard of him? he was really good on the veena. nice and mellow. i liked it much. now shes a disciple of sri lalgudi krishnan, the violin maestero (whatever that means). I thank God (/karma, or whatever) all the time for letting me be the student of a really talented person.

I see. Guitar is a different instrument in that, i personally think, some techniques that are used in Veena don't work on it. For example: bending the string is "difficult" than a simple 'slide'. I only do slides (so far) but my teacher said I will have to do 'bending' at some point where we do ragas that use the 22-note octaves.

No, I've just been learning for like 3 months now -- My teacher has taught me some basic arohanams and avarohanams, tests me randomly with random swaras. Nowadays, I'm getting better at real-time translation of "sound-in-the-mind" to "sound-on-the-guitar".

Chitti babuYes! A Stalwart! I heard that the front-row audience for his concerts are chosen by the sabha because he gets _very_ angry when someone in the front-row is not listening or is doing an out-of-sync Talam. He would walk away, it seems ( ... )

*dazed*

Err... what was that?

Did you try the 'demo'? :) Basically its a 'table-lookup' logic in an expression. Given a number, the expression tells you which cell it belongs to.

Its more like this: There were all these interesting equations floating around in school where you can do things like finding the greatest of two given numbers without doing an IF statement:

greater = ( ( a + b ) + | a - b | ) / 2
lesser = ( ( a + b ) - | a - b | ) / 2

and similarly, swapping two variables without having to use a third variable:

a = a + b
b = a - b
a = a - b

then we started creating our own problems... like "How to write a generic IF (a > b) THEN a = a + N ELSE b = b + N" kind of thing.

ah... it takes too much time to explain over here... lets meet up sometime :)
