The keys location of keyboard

There are 7 swaras or sounds in a keyboard, namely

S(called as Saa in tamil)
R(Ree)
G(Gaa)
M(Maa)
P(Paa)
D(Dha)
N(Ni)

. There are two sounds for some notes called as and to differentiate. The keys that vary are

R
G
M
D
N.

It is shown in the picture below.

Note that all 1's and 2's follow same pattern except for M which is vice versa when compared with others.

This is carnatic notation. Henceforth all my posts will be in carnatic based.

Below is the location of various keys on the keyboard.
