Dear Bhavesh, I listened to your downloaded
extract. however, Indian music does not have any universal rules to begin with.
just like a tailor, who measures your body before stiching your clothes, the
music teachers too, have to go through your strong and weak points before
preparing some practice excercises for you.
That is why, it is not possible to teach Indian
music through correspondence.
As some general rules are always there, so I am
quoting some of them.
1 Try to sing with the caraoke of your
choice.
2 If possible, get up in the morning and practice
for the lower octave.
3 immitate different voices is
possible.
4 Try to use lover tone while talking to your
friends. speak in base.
These are some of the rules and in no way are
exaustive.
