• P: Pa
• D: Dha
• N: Ni

Flat notes supported are:

• r: Komal Re
• g: Komal Ga
• m: Komal Ma
• d: Komal Dha
• n: Komal Ni

To play a high note, append the note with ' and to play a low note, append it with .

For example:

To play S at one, two and three notes higher,

S' S'' S'''

To play S at one, two and three notes lower,

S. S.. S...

To elongate a note, append it with ~

For example:

To play S for two beats, S. for three beats and S'' for four beats,

S~ S.~~ S''~~~

To give a pause, use -

For example:

To give a pause between S and R

S - R

To group notes together, encapsulate them in parenthesis.

For example:

(S'NDP)
