All great info and helpful as well. I was asked to clarify a few things, I will try.
When I say pull the Air through your lip, I mean while the Mouthpiece is setting ON, your Bottom lip, with the angled mouthpiece, NOT STRAIGHT, ( I use an angle cut).
MOST people, PUT the mouthpiece IN, they're mouth, I, do not, I lay it, on my bottom lip, not in my mouth.
I LAY, the mouthpiece ON MY BOTTOM LIP, and PULL the Air through my lip, not, OVER it, get my meaning?
By doing this, I can control the air greater, it is a learned thing, from practise, but you can tell the difference after many hours of playing the two different CUT'S, of mouthpieces. The angled cut, vs the round, is something you have to learn, you can pick both up, and play them the same, but after practise and TIME with the two different callers, you will tell the difference w/o a doubt.
What it actually IS DOING, the (angle cut), is creating a larger airway, w/o, enlargeing the inner diameter hole, so, you have greater range of tones with this cut, vs a none cut mouthpiece, because you now have more SURFACE AREA OPEN TO MANIPULATE, very little, but look at the size of the hole in the mouthpiece, takes very little to change a tone, and this opens it up to great ranges of playing. Playing an angled cut mouthpiece, is harder to control than a round, but more versatile in my oppinion, and, allows for greater kee kee, and Higher note to lower note DROPS, in tone, and Vice Versus.
When people say drop your jaw, they mean exactly that, you do not hardly notice it after learning it, like a kee kee, one day, you just have it, same with this. You do not lose the seal, you just simply drop your jaw in the note, to creat the two note yelp.
It is not drastic, just a movemennt, like holding a cigarette in your mouth, and opening and closing your jaw, while the cigarette is still in between your lips, no air loss, but you dropped your jaw creating a bigger sound chamber " IN ", your mouth.
Picture a Drinking straw, between two pieces of bread, flush, with the ends of the bread, thats how I PULL AIR THROUGH my lips, most, put the straw, past flush, and IN, they're mouth, get my meaning ?
