Its based on real flute Also try clicking space! use keys from- q - Pa, w - Da, a - Ni, s - Sa d - Re f - Ga g - Ma h - Pa j - Da k - Ni l - Sa'
The sound is not good because I didn't get proper sound track for note :( Note that in sargam there are- Sa Re Ga Ma Pa Da Ni but , represents down octave for example Ni, is lower than Sa and same goes to ' that are higher
