Carnatic music gives the artists freedom to exhibit their talents in many ways. RAgam ThAnam Pallavi, now-a-days known as RTP,
gives the maximum freedom! Sruthi bEdham in singing the rAgam, the beauty of different patterns in thAnam, the thALam intricacies
and lyrics of the pallavi are a few specials.
We can say that a Pallavi is a one line composition - either taken from an already existing krithi or just the one line composed
by an artist. The rAgam of the pallavi is indicated sometimes in the lyrics of the pallavi. A famous one is 'SankarAbharaNanai
azhaithOdi vAdi KalyANi DharbArukku'. This has four different rAgams - SankarAbharaNam, ThOdi, KalyANi and DharbAr.
The two number system of swarams, which the beginners learn, is denoted by the twelve basic notes, namely
R1 - shuddha Rishabham, R2 - chathusruthi Rishabham, G1 - sAdhAraNa GAndhAram, G2 - anthara GAndhAram,
M1 - shuddha Madhyamam, M2 - prathi Madhyamam, P - Panchamam, D1 - shuddha Dhaivatham, D2 - chathusruthi
Dhaivatham, N1 - kaisiki NishAdham and N2 - kAkali NishAdham.
Since the vivAdhi swaram shatsruthi Rishabam is same as G1, suddha GandhAram is same as R2, shatsruthi Dhaivatham is
same as N1 and suddha NishAdham is same as D2 the three number system came into existence.
It is S; R1; R2; R3 = G1 in two number system
R2, G1, G2 in the two number system becomes G1, G2 and G3 in the three number system
D1; D2; D3 = N1 in two number system
D2, N1, N2 in the two number system becomes N1, N2 and N3 in the three number system
The position of swarams are like this:
S R1 R2 R3
.......G1 G2 G3 M1 M2 P D1 D2 D3
......................................N1 N2 N3
Thus the twelve basic notes became sixteen swarams!
And, the beginner's rAgam MAyAmALavagowlA has these swarams: S R1 G3 M1 P D1 N3 S'
