This question already has an answer here:
I happen to have what I believe is called a bansuri. It seems to be of Chinese or Indian origin from what I can find out on Google, but I don't seem to be able to find note equivalents for it in a standard system, at best some kind of Indian note system.
In a standard music alphabet, what notes (and key) would an instrument like this play? Note that you need to approach me as someone who is a complete beginner in anything related to music.
