I'm learning without a guru, so I'm confused if my technique is correct or not. 3 months still I face hissing sound also whenever I start I have to adjust else the sound is improper in between.

Is pvc c flute ok and what should I buy next for transition.

Is taar saptak supposed to be a bit pinching in ear for C scale.

Also what channel should I follow to correct my posture once and for all.

Should I just use metronome or start playing in different taals

So far I'm just able to play titanic and some other songs by looking at the notes.

When can I actually hear the music by looking at notes what practice do I need.
