Okay, is this embouchure correct? Naturally I tend to play the lower notes as if my mouth is smiling and as I move higher, usually when I press the octave key, I bring the corners of my mouth in to hit the higher notes like I'm whistling. I'm not sure if this is correct can someone clarify for me. I've also read that with correct embouchure you shouldn't need to move your mouth at all. It's as if you're consistently blowing and when you press the octave key it just goes an octave higher no movement whatsoever and this doesn't happen for me I just can't hit the notes without bringing the corners of my mouth in. Which is this correct? I've only been playing for a month in a half (id that means anything).
