## Topic 37: Relation of 22 Shrutis with the 7 Natural notes

The % distances of all the 22 Shrutis from Shadja are actually the % distances within the 7 Natural notes ! (Refer to following table) Table shows Western Terminology of 22 Shrutis

For example, if we consider R at 112.5 as 100, M at 133.33 comes at 118.51.
If we consider G at 125 as 100, S' at 200 comes at 160.

Thus, 17 Shrutis as shown above are also based only at % distances between natural Swaras.

It can be seen that 2 positions of the same swara have appeared here, namely:

1. 1
2 Rishabhas : 111.11(R1) and 112.5(R2), and 112.5/111.11 = 1.0125
2. 2
2 Komal Gandhars : 118.51(g1) and 120(g2), and 120/118.51 = 1.0125
3. 3
2 Madhyams : 133.33(M1) and 135(M2), and 135/133.33 = 1.0125
4. 4
2 Dhaivats : 166.66(D1) and 168.75(D2), and 168.75/166.66 = 1.0125
5. 5
2 Komal Nishads : 177.77(n1) and 180(n2), and 180/177.77 = 1.0125

Very interestingly, the ratio between all these is 1.0125! This has to be therefore the ratio in all other missing Shruti-pairs (r1-r2, G1-G2, m1-m2, d1-d2 and N1-N2) also.

And in fact, it is so!

As we know now, this value of 1.0125 is the ratio of "Pramana Shruti".

Thus, one and all the % distances of 22 Shrutis from Shadja are actually found between the 7 "Natural" Swaras. This should be a great revelation.
