You are right.. I meant pitch and not scale. Apologies for loose usage
of the term.

OK. Let me try to define some terms (the way they are commonly
understood.) It will need a slightly long winded explanation but it is
worth it. A picture of the flute would have made it easier.
The tonic (Sa) of the bansuri is (defined as) the note produced when
the top three of the six holes are closed. So the Sa of a Kali 2
bansuri is the note produced when it is played with the top 3 holes
closed. The tanpura and accompanying tabla are tuned to this Sa.
- When the third hole is also opened, you get Shuddha Re
- When the second hole is also opened you get Shuddha Ga
- When you open the first hole you get Tivra Ma
- With the third hole partially open you get Komal Re
- With the second hole partially opened you get Komal Ga
- The first hole partially opened you get Shuddha Ma
- When all holes are closed you get Pa
- Shuddha Dha and Ni are obtained by opening the sixth and fifth hole
respectively. Opening the sixth and fifth hole partially gives you
Komal Dha and partially.
The precise microtone required is produced by controlling how much of
the hole is covered, and the blowing angle.
Hence, with this Sa you get the Kalyan Thaat when each hole is opened
fully (i.e.,no hole is opened partially.) All raags can be, and are
(usually) played in this fashion.
While your statement that you get the Bilaval Thaat by taking the note
produced by closing all holes as the Sa, etc. is true, Hindustani
Classical performers normally play with the top three holes closed as
the Sa. Depending on the composition, performers often play a raag
like Bhairavi with a bansuri with the tonic tuned to the Madhaym on
the tanpura.
Flautists playing light music often do what you have said, i.e., play
with different tonics on the same bansuri.
I think the above addresses Vivek's question as well.
