Rehna hai tere dil mein

I have used Sa Re Ga Ma Pa Dha Ni to write the notations. They can be very well mapped to Western notations as follows- Sa-C, Re-D, Ga-E, Ma-F, Pa-G, Dha-A, Ni-B. I have used # to denote lower octave, and ' to denote higher octave. For example, Sa#, Sa, Sa' stand for Sa in lower, middle and higher octave respectively. Hope it helps.

# represents lower octave

Rehna hai tere dil mein....
