I am teaching myself Bansuri (23", A scale), using YouTUBE videos.
Just recently I understood the concept of octaves, i.e. blowing sound hard and soft with same closed holes will produce high and low octave, respectively.
I am also practicing SA RE GA MA PA DHA NI SA
For past day or so, I noticed that I have to exert to make same low octave sound. Yesterday I didn't practice, thinking I need to give diaphragm/lungs a rest.
Today when I tried there were times I couldn't make low octave sound. I had to take deep breath from diaphragm and try again.
I am getting anxiety over this .... I really wish to learn Bansuri for hobby.
Question is, how to get consistent sound on Bansuri. Is it possible that I should limit practice to 30 minutes, daily, and take minute break in between.
