Hello Suresh,

Plain notes can simply be assigned a frequency. Most forms of music agree with 12 unique notes (frequencies), which are called as Swara(m)s in Caranatic music. Here is a link to my matlab code that plays the major combination of these notes:

Carnatic Music Melakartha Ragams - File Exchange - MATLAB Central (mathworks.com)

Gamakas are "details" between notes. Multiple types of Gamakas exist and these need to be considered individually. With Gamakas the focus is also on the magnitude and speed (time) in addition to the frequency of the notes (sin(2*pi*f*t+phi)).
