PS. I was trained classically in Hindustani classical & owned a harmonium. I preferred Sitar accompaniment to set the scale in my vocals.

Shows how much my disinterested self-involved 7-year-old self gave a shit about learning music :-D
However I stand corrected for having said "never".
i guess only in dhrupad they get very close to this approach. you would take forever to tune the tanpura to your tonic and 5th (or 4th) above (depending on raga), low tonic. now if your tonic isnt a standard note, you would first tune the tanpura to your tonic (by humming), then you understand the 'relationships' between your tonic and your 5th (or your 4th) better by tuning (ie listening deeply to) the tanpura cos you cant simply dial up a standard note. its a whole different world.
one could argue why not tune the harmoniums notes into your personal tonics and 5ths and 4ths and all other notes but of course its tedious, the other deeper idea is in indian classical music gurus wouldnt quite fix the position of a 'note' in the raga, its fluid, it emerges, its rediscovered (the ahha happens here) etc.
what is happening now is as harmonium is immensely popular they start to rewrite history and say well indian classical music wasnt about finding your own tonic after all...u are no special...u were waiting for our standard notes...u are just like us....but not as good as our beethovens and mozarts ;)
I am from Europe and my mom has so-called "shruti box" which is basically harmonium with fixed chord on it and it's used to play drones. Shruti box is considered exotic and Indian here and it's almost unusable for anything Czech, because our music do not rely on drones too much.
The harmonium uses reeds as the primary oscillator.
It's like the difference between a recorder and a clarinet.
