Above and beyond entertainment value? I agree there isn't any need to play a triple C. With perhaps a few exceptions I'll list at the end. But to quote William Costello (from the book)0
"A man who can lift 200 lbs over his head will surely have no trouble lifting 150 lbs. Or even less so 100 lbs".
It's a loose quote but pretty accurate.
If we compare the "200 pounds" to the triple C?
Then the double C is analogous to the 150 lbs. And yes I've seen and played lead trumpet parts with double C's and notes close around it.
Unfortunately for me the way my chops used to be programmed only allowed me to JUST BARELY be able to play double C. In other words I was like the man who could just barely lift 150 lbs.
Now had this been my only problem I'd have been fine with it. However that "150 lbs" took EVERYTHING that I had physically. Comparing it to the double C that is.
And after playing that double C I wasn't worth much to the band afterwards. Because I had expended most of my reserve energy.
In the Stevens-Costello method we set the embouchure to be able to blow this double C from the very start. Beginners learned the embouchure and started out making little "statics", squeaks or "cyclonics" come out of the horn. Just wispy little tones. Some people catch on right away. Others like me take longer. I had to make a mouthpiece change (larger) to pull it off.
We shoot for high G at first but accept the high C. Resting often because tired chops can not learn much and the whole process of playing while exhausted produce bad habits.
Soon as we get a wispy little high G we continue gaining control and range. I continued above the high G until I could sustain a few notes above double C. Like an E or F/double C. At this point?
I knew that I was setting my embouchure as directed by Stevens-Costello. Because if I hadn't done so I wouldn't have been playing so high to begin with!!. THAT'S PART OF THE TEST! The goal of starting out playing extremely high notes is not necessarily to become a screech player BUT AS A CHECK TO PROVE THAT WE'RE PLAYING CORRECTLY!
That was last November. Soon as I could get notes in or around double C I took this same embouchure and worked it down to my concert B flat tuning note. NOW I started playing conventional exercises. It is at this point where I can't really fail.
Because we all know that building a middle register is far easier than building an extremely high register. And the low register is much easier than the middle one. Our teachers all started us out in the middle and lower registers when we were kids because,
A. Teaching lower tones is far easier than playing high ones.
B. Our teachers never knew any better.
This is what Roy Roman calls the "Evolutionary Method". And again WE ALL WERE TAUGHT THIS WAY.
The main problem with the evolutionary method is that only a small fraction of those playing this way will ever develop the complete range of the instrument. This is because only a small % of trumpet players have teeth, lips and jaw etc that automatically place their embouchure in the CORRECT position to allow extreme range.
One of my own beliefs, outside of the Stevens System is that perhaps these lucky few also have a particularly elastic surface on their upper lip. The part that vibrates on their lip is well suited to sustaining a vibration in the extreme upper register.
Not so for the rest of us. Our chops USUALLY tend to be incorrectly set up to allow extreme range. So we mash the mouthpiece into our chops. Our range has a ceiling. Usually we're limited to a High C to D area. I was a little luckier and had a workable and nice sounding G/High C.
But it was so hard to blow! And difficult to just "sit on" for any length of time.
If you remember only ONE THING about the Stevens-Costello method it is that we demand that our teeth NOT GET IN THE WAY OF THE LIP/AIR intersection!!!
So many trumpet players do not understand this! Way back when I was in the road I decided that although I didn't have the time to convert my chops completelyover to the Stevens-Costello system that never the less I was at least going to KEEP MY UPPER LIP IN A POSITION WHERE MY TEETH DIDN'T BLOCK IT FROM VIBRATING.
What a freakin eye opener that was! PLEASE TAKE NOTE OF THE FOLLOWING. PLEASE BELIEVE ME!
Back on the road playing 5 nights/week plus rehearsals & travelling. It all took a toll on my chops. While I didn't need to play any high F's and G's on my gig I still had trouble with endurance and power up to High C and D. The singers demanding that I play louder.
Well that took a lot out of me. I tried all sorts of ways to conserve my strength but then I remembered the number 1 point in Stevens-Costello. Roy Stevens said,
"You can't play on your teeth".
Meaning that most of us do not leave enough upper lip below our upper teeth. In order that is to sustain a vibration in the upper register. We're always fixated upon our lip position on the mouthpiece. Forgetting of course that our upper teeth are equally important. The teeth act like the other "bookend" to the teeth. I guess that another term could be called the other clamp on a vise.
If our teeth cover too much of the upper lip? The tone will usually cut off somewhere as we begin to ascend into the upper register. Or the tone can grow weaker.
So right then and there I decided to DROP MORE OF MY UPPER LIP BELOW MY TEETH!!!
Almost immediately after consciously pushing my upper lip down a tad my strength to blow high C and such more than doubled. I could BLOW the roof off of the room throughout my whole range!! A high C and D felt like nothing. I could blow them at will, all night long and loud as hell. The guys in the band loved my new way of playing. This meant better job security and a more friendly atmosphere in the band.
Granted that my "practice room range" didn't increase. Nor would it because I hadn't converted completely over to the Stevens-Costello design. Like I'm doing now. My sound (back then) had a serious ceiling around a high G. But at the time it hardly mattered.
So I can see why people have questions about Stevens-Costello. A working musician probably shouldn't expect to convert completely over to Stevens-Costello. However he can still pick & choose those universal elements that may support his existing limited embouchure. As I just described.
Back to work now!
I'm from among the lucky few who aren't.much affected by the endemic. Being retired and hsve a small business that largely comes to me thank Gid. So I have plenty of time to convert over to Stevens-Costello. This is my fifth month into it. And am progressing nicely.
But I want to share a caution to all!
My right, front incisor broke off in August of 2018. Due to roughly 46 years of jamming for my high G's and whatnot. Thus my old way of playing was history. I couldn't play trumpet for crap.
Now had I fully converted to Stevens-Costello at a younger age ? I might very well have saved that tooth. Incidentally my Stevens-Costello embouchure is completely unaffected by tooth loss. While on my old embouchure?
My former way of playing is ruined.
