Here's a blast from the past for you: In the early 1960s during the height of the bosa-nova craze, Stan Getz' saxophone was stolen from his Corvette parked outside a Greenwich Village (New York) nightclub. A columnist writing for the Village Voice newspaper announced the famous saxophonist was offering in excess of $1,000 dollars for just the mouthpiece.

[@rudva]

[@Smackdabinu]

Hey Jay, I’m wondering if you ever heard of, or had dealings with,a man by the name of Claude Humber? He lived in Dallas Tx in around 1970-80s. He was a professional “hand surfacer” for sax and clarinet mouthpieces. He also sold his own hard rubber blanks. He had a handwritten book of all the work and measurements he had done on so many professional musicians. It was incredible to see Coltrane, Parker, Hodge, Carney, Getz, Basie band, Ellington band, Welks orchestra and many more. And he only charged $5.00 to surface it, to how you wanted to sound, and $25.00 for his autographed blank. Man, it must’ve been a trip, seeing and hearing these sax legends sitting at his kitchen table while he worked on their mouthpiece!! “Those were the days!”

[@alejandrodonceltalavero7385]

I remember your solo on a world sax collab Jay and so good, i wanna say for me a word can be good for your playing is the perfection, i don't know you play so perfect, perhaps i wanna listen of you something more free or wild but is so good, thanks. I love the classical too, i went a conservatory, Marcel Mule reminds me so many things hehehe.

[@bobjacobson858]

Thanks for this informative video. I play clarinets and brass. I'm aware of the subtleties of brass mouthpieces, but I didn't realize there are several designs of single-reed woodwind mouthpieces that influence the sound the instrument produces.

[@joekappes8648]

Great presentation J! Thanks for clearing up so much of the Internet propagated ignorance that we see on forums about how mouthpieces work. You already touched on the difference in materials in your Jody jazz comparison where you pointed out that their darkest mouthpiece is metal. I would love to see you dive into a materials comparison a little more deeply with different brands comparing metal versus hard rubber versus 3-D printed ABS plastic and dental resin. And one last subject that I feel is very underserved - comparison of different types, not just brands but types/cuts of reeds. Vandoren has some useful comparison videos of the different cuts within their own brand but I’d love to see you compare some jazz cut, classical cut and other reeds. I think many players who complained that they have tried a mouthpiece and immediately found it to be unplayable might have been better served by trying different types of reeds. It’s an expensive habit but that’s what we sign up for when we choose a reed instrument.

[@bettersax]

Joe, that's a good idea for a video. Would need to have the same exact mouthpiece mad in three materials for that. Honestly material does make a difference, but not as much as the shape or precision with which the mouthpiece is made. For me, the material has a huge impact on how it feels to play a mouthpiece which is very important.

Hi and thanks. One type of baffle you didn't mention is the absence of any baffle having no baffle at all. My Jody Jazz Custom Dark tenor mp appears to have no baffle. I assume that and the large chamber with scooped side walls are what delivers its warm spread sound. Personally, I love it!

Hard to beat a Berg Larsen IMO. I play a 90/1 for Alto, and 110/2 on Tenor. Classical, Lead Jazz, and Bebop. I have many many many mouthpieces ( Meyer, Peter Panzol, Otto Link, 3D Printed,, and I always go back to the Bergs...

[@kjell-akeapell3285]

How does a flat baffle look, a roll over and what,s the difference?

[@JeffreySaxophoneTallNewton]

Over time, you'll find a way to get "your sound" on any saxophone, mouthpiece, reed, ligature, etc. you please. Mouthpieces in particular are roughly analogous to wardrobe choices at best, and the player can "wear" them in this fashion. Some mouthpieces "match up" with certain saxophones and players better than others, for acoustical physics reasons. Actual saxophone tone, as with the voice, is largely determined by the physical attributes of the player. At least that's what Stan Getz said, and he should know a thing or two about saxophone tone.

Bonjour, dommage que votre émission ne soit pas traduite en français. J'adore tout les contenus de la chaîne. Cordialement. Fréd.

[@bettersax]

Désolé

[@Ithirahad]

This begs one to ask: what happens if the ramp rolls UNDER instead of OVER? In other words, what happens if there's a concave curve inside the mouthpiece? Do you get a super round, dark, and flugel/French horn-like brass sound? Do you create a honk that could knock down the walls of Jericho? Will the mouthpiece simply fail to sound at all because it messes with the pressure differential between the inner and outer sides of the mpc? At an extreme, what about an anti-step where the baffle goes up at a high angle and then turns to nearly flat?

[@ElekhtroLT]

Question: what type of mouthpiece was used in the 20's and 30's and later into the century, featuring among the saxophonists in bands such as Guy Lombardo and His Royal Canadians? Was this intermediate sound being able to project but also to control the dynamic range created by the emergence of different baffle mouthpiece + classical embouchure, or the other way around - classical mouthpieces featuring modern adaptation of embouchure? Thank you for your videos, they are really helpful.

[@derekakien7379]

Hi. My teacher ran big bands during WWII. He said the guys would use chewing gum in the mpiece to improve the sound. Probably very little choice in those days.

If you are playing classical saxophone and need to blend with others in that style you will want an appropriate mouthpiece to make that easier.

[@frankiegray4569]

Great informative video....all this info holds up very well if ur doing an acoustic gig...but when u play thru a mic hooked up to an amp or pa system, mouthpiece dynamics dont really matter as much as far as sound goes....especially when U have the volume, echo and reverb effects going...Gato Barbieri played with tons of effects so I don't think it really mattered which of his mouthpieces he used..and for most pros, we usually always blow thru a mic

[@justinjohansen5992]

I agree with this. Once you are in a heavily mic’d environment, you might as well just play what’s most comfortable. When I was playing a lot of tenor in heavily mic’d settings, I just used an off the shelf Otto Link STM NY 6* for everything. The difference between old school swing and modern funky stuff was just bumping up the reverb and presence.

[@frankiegray4569]

@@justinjohansen5992 there U go! I think most sax players feel the same way..it's when U play somewhere acoustically that ur mpc becomes crucial in ur sound..be well my friend!

[@bettersax]

Yes, always go with the mouthpiece that gives you your best sound. However, sometimes you may want that sound to blend well with a funk band and have more higher frequencies in it, while other times you may want your sound to blend well with an acoustic piano, bass and vocalist. I totally agree that one solid middle of the road mouthpiece is the way to go so that you can use it on any kind of gig. (that was the basis of the design for the Burnin' mouthpiece). Some people can get a dark sound on a step baffle piece or get a bright sound on a low roll-over piece. Most people are not at that level though.

[@craigscott3133]

Hi Jay, Got a problem maybe you can solve. I have a tenor and have used a Selmer C* to play in concert bands etc. However, I wanted to go to a brighter sound as I played jazz and got a Jody Jazz HR. But the JJ is too big for the cork on my neck, while the Selmer fits fine. I've tried plumber's tape to build up the neck but that doesn't seem like a good solution. Should ai just go with two necks or is there a cheaper solution to this? Thanks!

[@bettersax]

Craig, have a new cork put on by a repair technician. Doesn’t cost much.

[@TransformsIntoAGuitar]

[@Androcentus]

Not a word about the popular Vandoren V16 metallic pieces...Are they that bad???? Got a T6 small recently and it's beautifully crafted, although I found so difficult to blow air into it with any reeds bigger that 2.0...Am I doing something wrong? Thanks!

[@bettersax]

No those are good pieces but they are very much inspired and based on Otto Links.

[@MrGuto]

Jay, your description of a rollover baffle, with an arrow pointing to the bump in the middle of the baffle at 2:00 is surprising. Theo’s website explains the rollover that characterizes this type of design is right at the tip! He refers to it as «a short round at the tip» with a drawing showing it. I’m so confused.

[@bettersax]

On Theo Wanne's website there are 2 arrows indicating the baffle. "The baffle is the section of the mouthpiece directly behind the tip rail that extends back into the mouthpiece about two centimeters." hope this clears things up. My arrow is pointing to the middle of the baffle section.

[@MrGuto]

@@bettersax I guess this means the entire about two cm of baffle being curved as a "bump" is what characterizes a rollover baffle. I always thought what mattered most was the slight bump right under the tip. thanks for the clarification.

Yes those combinations exist.

[@matta5348]

Off topic, but was Coltrane a small-statured guy? His horn always looks so big on him. Obv Canninball was a big man and played alto, so his horn always looks small, but Trane always looks like he’s playing an outsized horn.

[@chriscoulter1358]

Matt that’s a great question-I always felt that the tenor in the hands of tall/bigger guys like Dexter Gordon, Sonny Rollins, Micheal Brecker certainly must have been more physically comfortable than say in the hands of shorter guys like Jimmy Heath Joe Henderson and Johnny Griffin yet they are all amazing and all handled the horn with no discernible difficulty!

[@cliveastle9372]

Jay - On advice from his private sax tutor, I'm thinking of upgrading my son's mouthpiece from the Yahama 5C he currently plays to a higher level one and your new tenor burning sax looks/sounds interesting. Do you think your mouthpiece is a good choice? He is almost 14 (7th Grade), has 3 years of tenor under his belt and plays in both the school symphonic and jazz bands and made the area All County Jazz Band (only took 2 tenors). Do you think the 6 tip opening would be the way to go or maybe a 7? We will also be upgrading him to an intermediate or higher level horn here fairly soon. Thanks! We enjoy your videos a lot!

[@bettersax]

Steve, glad to hear your son is doing well with his saxophone playing. Good for him. The Burnin' would be a great choice for him playing in the jazz band for sure. In the symphonic band he should probably stick with the 5C as it will blend well in that type of ensemble. There will likely be an adjustment period for him as he has only ever played the Yamaha mouthpiece and switching to your first upgraded pro level mouthpiece takes some getting used to.

Its actually a Selmer S80 C*

[@bettersax]

Yes, you are right. For whatever reason we always just refer to these as C* when that is actually just the tip opening not the model of the mouthpiece. I should have been more precise...

[@TransformsIntoAGuitar]

I'd like to know how shapes affect altissimo.

[@bettersax]

This is a great topic for a video actually. I have come to realize that altissimo does not depend on any particular shape of the mouthpiece interior since I can get altissimo pretty easily on any mouthpiece as long as it's well made and the reed is good. Some are easier than others for me, but I suspect each individual will have different results depending on how they blow. Classical saxophonists can shred altissimo with no baffle at all so I think that is a bit of a myth that you need a high baffle for it.

[@TransformsIntoAGuitar]

​@@bettersax I couldn't get altissimo on my Selmer classical mouthpiece so I bought a SYOS and was able to get it. When I tried again on the Selmer some months later I was able to get altissimo on the Selmer. I think mouthpiece shape facilitates it, especially when learning.

[@eliwyatt2292]

I know there’s a lot of myths about what previous players used, but didn’t Trane have a wedge, or makeshift step baffle put in his mouthpiece? It sounds like in his earlier recordings it’s not there but in the later ones his sound is much edgier.

[@bettersax]

I have heard that many times yes. I cannot know really what setup he had exactly in that clip, but earlier Trane sounds a lot more Roll-over baffle than added wedge baffle to me.

[@SchielMusic]

It's a little misleading to call the Selmer S80 mouthpiece a "C*". C* indicates the size of the tip opening, and the S80 is available in several sizes C-F (C* being a little larger than a C). Several models of Selmer mouthpieces are available in size C*

[@bettersax]

This is true. In the old days we always just referred to them as C* even though the model was S80 or S90.

Irony is in the Brecker clip he's playing a Link.

[@kenjett2434]

Well I agree that mouth pieces can change how a sax can sound but without a good reed no sound can be generated. Why is a Reed geek so important in correcting imperfect reeds? Why is it only a percentage of reeds out of a box is fitting to use in a gig? Even a beginner mouthpiece can generate sound plenty good to do a gig. A mouthpiece is also made of pretty tough material while reeds are very delicate and easy to destroy or make unplayable. So although a mouthpiece can have design changes that aid in certain styles of music. The Reed has to have that perfect fit in order to reach that sound or any design change in a mouthpiece is irrelevant.

Hello , after watching this upload three separate times now there is a clear need to rebuff the whole message of your presentation . Firstly , you have not explained anything regarding how a reed mouthpiece works - that is how it generates sound. By dismissing that issue you then eroneously make false statements about the baffle . That confirmed to me that you don't understand how a reed mouthpiece both creates the 'attack' of sound and how the baffle functions . Secondly, most of your presentation continues to reinforce and give creedance to the error that the mouthpiece somehow regulates the character of the sound by altering the 'flow of air '. This lack of understanding of schoolboy physics regarding the relationship between air and how sound is transmitted needs to be addressed . Thirdly ,like all public figures,and you have become one with the many videos here , a certain duty of care and accuracy is expected regarding the facts . The whole presentation is based on false presumptions and lacks facts. It is so simple . The player squeezes the reed up towards the mouthpiece top rail then pushes/ blows/ injects air in the space. This creates a 'venturi ' pressure passage lowering the pressure in the space . The two reed 'wings; and centre tip are pulled further in closing the gap until the elastic strength of the reed pulls them back . They then snap back under air venturi induced depression slapping the air against the top rail and 8mm or so of the inner baffle creating a series of repeating sound waves . These sound waves can only go into the mouthpiece where the side rails, lowerbaffle and throat shape and size ,by reflection , alter the charcter of the sound. At this stage the flow of air has done it's job and is just an exhaust waste , Its the flow of reflected sound waves completetly independant of any air 'movement which creates the character. Obviously the more air pressure you inject into the venturi tip space the louder the sound .Once that sound has been made its out of your control and dependant on how its reflected against the baffle,side walls undersid eof the reed which is not moving and the throat Just for the record, sound waves are transmitted through still air , at sea level at 1125 ft/sec.(or 343 m. persecond .They do not travel any faster or slower in moving air . nor are altered by the flow or direction of that air. Do what you like but you cannot blow sound waves down a tube as they are travelling much faster than you can blow . You can deflect soundwaves with solid objects by natural reflection and alter the pitch of a sound within a tube by adjusting its length . This is acheived when the constant uniform reflection of the sound waves inside the tube is interupted by a hole . Please read and re read this comment and try to forget all that the fancy mouthpiece makers tell you about 'air flow'. Its a nonsense and so obviously so . Jonny Uk
