Hi all, I've recently started noticing that if i play any notes above an F (top line), my sound gets overpowered by the sound of air. My current slow solo (An Untold Story) ends on a top Bb and whenever i play it it sounds horrible because of the air. I have checked my mouth and it's not escaping out of the corners of my mouth, and when i play a top Bb, withdraw the note but keep blowing, i can still hear the air. Is it just the natural way instruments work where you blow air through and it's audible, or am i doing somehting wrong???
