Hey guys, i am new to flute playing and i have been playing since 5 months. So, i want to know how to get rid of the 2nd octave rough tone. I have seen various fonts and practiced alot of soft long tones, but my tone does not get any near to the normal flute tone that we all know. Please tell me as much details as possible, such as embouchure, how to control air, etc. that can fix this.
