It's great to hear from you!! Happy New Year!!!
NEVER can you reduce a playing problem to one thing-NEVER. That does not mean that every position is the same - but I never said that. Everything is connected. Realizing that is the first step to effectively helping someone.
I have to agree. But just like a heavy footed driver of a car. Many parts are at work but if I can get them to reduce the pressure on the gas peddle, they will get less speeding tickets. Sometimes adjusting one thing can cause a host of other things to align.
For example, proper adjustment of the horn as we ascend and decend can make a big difference.
Successful playing is ALWAYS the connection of many factors. Changing the embouchure does NOT connect breathing, hearing and body use - in my experience where most of the sins start.
Yep, I agree. Unfortunately many people see an embrochure change (along with a screamer mouthpiece) as "the silver bullet" and will turn them into Phil Smith in six short weeks. Proper consistent practice is what's required.
If a dedicated player does not have range after years of practice, then no silver bullet will cure that.
That in my opinion is a problem. If a person can not play in the register the music is written (for example E or F above high C), then they are using some faulty mechanic (usually forcing something). High notes are not hard. they just take more focus because the partials are closer together in the upper register. The neat thing is that fingering is sometimes optional when you get that high.
Range starts with a relaxed body, breathing and well developed habits in the lower registers. It continues with a methodical approach to improving what needs to be and not just beating the chops up.
The only thing I would add to this is that they need to be able to hear the note in their head and (for lack of a better way to describe it) feel the note in their mouth.
