The Landing: The Final Focus and Seal

Author’s note:  In the three years since this article was written, I’ve come up with some newer ideas on how to set the embouchure.  The information in this older article that follows below still stands, but the new ideas offer an easier way for some players.  So if you find any of the articles from the “Landing Series” interesting and helpful, be sure to also read “Teaching an Old Dog New Tricks (or How to Break Old Habits)”.

The trumpet is an incomplete instrument, which needs to interface with its human counterpart in order to have the ability to produce sound.  For optimum performance, the human component of this hybrid instrument must be made with the same degree of precision as the design and manufacture of the trumpet and mouthpiece, otherwise the compromises that can occur (due to the player’s inherent physical structure, lack of knowledge and/or awareness) will most likely negatively impact the player’s ability to make music.  Can you imagine the problems that could happen if the threads of two connecting water pipes were not of matching sizes, were stripped or misaligned, or if they were only loosely screwed together?  Parts One, Two and Three of this “Landing” series discussed how to set the lower jaw, approach angle and landing of the incoming trumpet (with the ideal mouthpiece placement and the distribution of the mouthpiece weight) in order to best match the flat rim of the mouthpiece, and how to create the ideal underlying structure for airflow, lip vibration, embouchure focus and seal.

By then stopping the incoming mouthpiece weight when it first contacts this ideal preset of the embouchure, the player will have taken all of the steps to create the best possible seal before involving any action of the embouchure musculature.  This extremely close proximity of the mouthpiece serves as a great reference…meaning it will clearly reveal what specific gaps still remain, and what exact shape the embouchure must assume to complete its interface with the mouthpiece.  This embouchure “sandwich” (like the filling of the Oreo cookie) between the mouthpiece rim and teeth (with their irregularities) must fulfill much more than a role of a seal or gasket though, for it also functions as the instrument’s reed and facing (the top and bottom lips, respectively).  That means the act of sealing the interface between mouthpiece and teeth formation must be done in a way that does not disrupt the vibration of the top lip, but that instead increases the efficiency of its vibration.  This efficiency is achieved by also simultaneously focusing the size and shape of the lip aperture, all the while making sure the top lip is as relaxed as possible.

This is a tall order for the embouchure muscles, but even though everyone has a different facial structure, the same procedure can be taken by all to complete this final step of assembly.  A useful image to hold in mind is the cutting action of a pair of scissors, or actually two identical pairs for our example (all of these images will open with a new window so you can refer to them at any time during the reading of this post).  Most of the cutting energy is achieved by the four fingers gripping their handle, which is below the fulcrum (the screw) of this lever, on the opposite side of the screw from the moving top blade’s downward cutting action.  The thumb, which is above the screw and controls the stationary, lower blade, is generally relaxed…which stabilizes the lower blade (and the scissors in general) for more precise cutting control.  As the grip on the lower handle increases, the top blade comes down on the lower blade (action #1, felt most closest to the screw), while the contact point of the cutting action gradually moves towards the end of the blades (action #3).  The last part of the blades to touch will be at their tips.  The #2 action, which is related to the embouchure and not to this scissor analogy, will be discussed below.

This is no news to anyone who has used a pair of scissors, but it is a great analogy for the making and the holding of the embouchure.  The picture here shows just one pair of scissors superimposed over an embouchure in the “M” formation, with the screw of the scissors directly over one corner of the lips.  The right side is scissor-free in order to illustrate the 1/4″ teeth aperture (represented by the little boxes), centered lip line (where the lips meet in relationship to the teeth aperture), lip aperture (tiny blue slit) and mouthpiece placement (2/3 on bottom lip).

A look at the muscular structure of the face shows why the muscles above the corners must remain fully relaxed.  If they are allowed to contract, the reed of the top lip would be pulled up and away from the facing of the bottom lip with a sneering action, and/or the lips (and the sound) would be thinned out with a smiling action…causing the corners to be stretched back…which would also raise the lip line, break any semblance of a seal, and destroy the lip alignment.  These actions leave the lips weak (although tighter), unsupported with air, and prone to injury from mouthpiece pressure.  There is only one case where a slight smiling action could be allowed, and that would be if the lip line is naturally too low.  The thinning action could be used to raise the lip line (and the corners) to the place where they are centered between the teeth, but at that point the muscles below the corners must lock the embouchure into place.  The “braced muscles” (labeled on the right) do not actually contract, but as the lateral walls of the oral cavity, their ability to channel the airstream also helps to provide a matching resistance to the intra oral air pressure, which is how the air supports the embouchure and efficiently governs the tension of the lips.  The amount of intra oral pressure naturally increases as the embouchure becomes more focused and/or the airspeed is increased.  You can also see how the lips are one round muscle, and that the bottom lip is supported below by much larger, thicker muscles than the muscles above the the top lip (proving that it really does take more muscle to frown than to smile!).  This design makes the bottom lip an ideal facing, for it will not vibrate as easily as the top lip, and it is more suited to receive a little more than half of the playing weight of the mouthpiece (which also helps keep the top lip freer to vibrate).  When both lips and corners (the “modius,” circled in red) are equally spaced between a 1/4″ teeth aperture, the corners (the fulcrum of the “scissors”) are situated in the perfect place to function as the anchor of the embouchure.

The lips play a vital role in so many of our daily functions (speech, eating, communicative facial expressions, etc.), so they are packed with blood vessels (hence their deeper color) and nerve endings (a large part of the brain’s surface area is devoted to the lips).  This is one of the reasons that kissing is so pleasurable, but it also means that a trumpet player can feel the smallest changes in tension and areas of contact.  Lucky for us!  The muscles below the corners are the ones left with the multi tasked role of shaping the lips into an embouchure design that both seals and focuses.  However, just flexing these muscles alone does not guarantee that all of the necessary details will be addressed.  A clear image of those details, monitored by a mirror and a keen sense of feel will direct the proper muscles into a very refined grip. If we make sure the muscles above the corners do not come into play, and that the jaw remains stable while setting the embouchure, the correct musculature will learn to master not only the fine degree of coordination needed for correctly setting the embouchure, but also for playing….they are the same complex action.

To set the embouchure, start with the lips parted, so you can see both the top and bottom teeth edges, and then set the lower jaw so that it is slightly ahead of the top teeth (see Part Two of this series for more details).  Next set the teeth aperture so that there is a 1/4″ gap between them (about the diameter of a standard wooden pencil, which can be used as a gauge).  You may notice that the corners of the mouth are already (or close to being) centered between this teeth aperture, which is exactly where the lips should meet when they come into contact with each other.  This jaw position can be locked with a tongue stop (seen at the right, where the tip of the tongue touches where the bottom teeth meet the gums) in order to learn how to keep the jaw stationary when setting the embouchure.  Now let’s examine each of the three simultaneous “scissor” actions of the embouchure, governed by those muscles below the corners.

Top Lip Down (Action #1)-  This should always begin with the act of relaxation.  By releasing any tension in the top lip it will naturally drop down and be in an ideal state for vibration.  The top lip must come down until it occupies 1/2 of the 1/4″ teeth aperture, from corner to corner (also illustrated in Part Two), keeping it exposed to the optimum amount of air.  The muscles below the corners are used to bring the top lip down any remaining distance to this position, 1/8″ below the top teeth edges, and should never cease with that act during playing in order to hold that position, otherwise the body will look for other ways to maintain lip contact (like mouthpiece pressure or squeezing the bottom lip up).  I have a saying:  “Never give up on top down,” which rates right up there with “Never let go of your trumpet while playing.”  Note: some players drop only the center of the top lip (which is contrary to Action #3, described below), which makes the center (instead of the corners) the point of greatest resistance…not a good idea.  Bringing the top lip down in a way that is felt at the corners first is the Scissor Action (#3), which is the best way to decrease the size of the lip aperture while still allowing the center to be free.  Keeping the top lip down is the best way to keep the lips in contact with each other.

Bottom Lip Hugs (Action # 2)-  The “hugging” action evenly inverts and aligns both lips from corner to corner (see the picture with the single pair of blue scissors above) and is again accomplished using the muscles below the corners.  This happens in front of the teeth (rather than “sucking” the lips into the mouth between the teeth, which is usually accompanied by a “smiling” action of the corners) and essentially hides the red part of the lips completely.  It is also important to achieve this inverted position without squeezing the bottom lip up, for that action tends to close the center…making it, rather than the corners the point of greatest resistance.  This also pushes the top lip up past the top teeth edges, effectively starving it from the supporting airflow.  The bottom lip’s hugging action makes the bottom lip a stable foundation for the top lip’s downward force.

These crude diagrams of the side views of a pair of pinkish lips (and generic caucasian skin) show various degrees of contact (in red).  Diagram”A” represents the lips touching in front of aligned teeth with a 1/4″ aperture (none of these are accurate in scale).  “B” show the lips “chasing” the airstream…which enlarges the ideal paper thin lip aperture, decreasing its efficiency and contributing to an airy, flabby and/or distorted sound. Because this shape protrudes into the mouthpiece cup, one of the instrument’s resonant chambers becomes smaller, which means the overall sound is also smaller and less resonant.  “C” shows the correct hugging action’s larger area of contact, where the lips are still in front of the teeth, and the lip line is centered between the teeth aperture.  “D” shows the bottom lip squeezing up, which results in the high lip line described above, and a much smaller area of contact.  Compared to “C,” you can see the upward motion of the bottom lip is not equipped to hold against the vector of the incoming airstream.

When done correctly, the hugging action fulfills many vital embouchure functions. Inverting the lips from corner to corner against the teeth (the modius should be felt hugging against the 1/4″ teeth aperture) is much like the way a sail catches the wind and converts it into useful energy.  If either the sail or the mast (which the lower jaw functions as) are not held in place the energy of the wind cannot be harnessed (lips that are allowed to “chase” the air, like Diagragm B above, are more like the flag flapping in the wind at the top of the mast).  This analogy also underscores why it is so vital that the bottom lip is exposed to air from corner to corner within the 1/4″ teeth aperture, and why the jaw should remain stable.

The greater area of contact area between the top and bottom lips shown in Diagram C produces a much “thicker” sound.  Could you imagine what a viola would sound like if its bow only had one horse hair?  The sound would still be there, but because the contact area would not be as great, the vibration of the string would not be as robust.  Note: the lips are very pliable, so even very large, full lips can be inverted, which is one of the easiest ways to instantly improve the sound.

The hug also helps to align the lips…not just the vertical alignment stemming from the matching inversion of the lips and the forward lower jaw position (like Diagrams A and C above), but also the horizontal alignment, which influences the size, shape and location of the lip aperture.  The picture above shows a common, naturally occurring lip shape at the center of the top lip called a Cupid’s Bow (circled in blue) which could lead to two apertures (the small yellow ovals), as the lips come in contact with each other.  However, mastery of the hug will produce precise, even, and gentle contact from corner to corner, and (along with Action #3, described below) a small, centered, paper thin lip aperture.

Scissoring in from the Corners (Action #3)- this occurs naturally as a result of combining  Actions #1 and #2, which focuses the lip aperture towards the center rather than squeezing and/or closing the aperture at the center, all the while keeping the corners at their natural width.  In this way the lip aperture can be very small and yet still be very free as the embouchure’s point of least resistance.  Because the muscles (below the corners) that govern this small focused area are relatively farther away, the tension is also farther away from the point of vibration.  This also helps the lower register’s form and sound, since the lips can still retain their proper position.  The player should be able to feel the width…the outside edges of the lip aperture (described by some as the “artificial corners”), well within the inner rim of the mouthpiece.

Assembling the embouchure in the way described above can cause the muscles below the corners to flex in a way that actually begins to change the shape of the facial platform the mouthpiece rests on (the way any muscle can change shape when it is flexed).  This means that there is one more function of the muscles below the corners!  This diagram can be misleading though, for there is no “pooching” out (I hate terms like this) of the lips at the points of contact with the sides of the mouthpiece rim. Underneath those contact points both the top and bottom lips are still engaged in the scissor action.  While the proper jaw position and horn angle can minimize the amount of mouthpiece pressure needed for a good seal, the muscles below the corners and the bracing muscles of the lateral walls of the oral cavity can take the minimal pressure concept even farther…protecting the center of the top lip from any remaining weight needed for the final seal, or from careless mouthpiece pressure arising from an uninformed “landing,” lack of air support or poor posture.

A common problem players have when learning to make this set is using far too much tension, especially at the center of the embouchure (in the form of squeezing the bottom lip up when inverting the lips, or pancaking/flattening the bottom lip and chin muscles).  Also, the tongue should remain relaxed and low (unless using the tongue stop, described above), as should the upper body, and throat.  Noticeable improvements can be experienced even before this setup is perfect.  Any practice that brings the embouchure closer to this position will produce predictable improvements in sound quality and performance.  I see this every day with my own playing, and with my students….with beginners and with those who have been playing for a long time.

For most players it will take a while to assemble their embouchure with the degree of precision that honors all of the points discussed here, but when this blueprint is the basis of a clear mental image that oversees the setting of the embouchure, the player can progress much faster than more traditional ways of learning how to play the trumpet that prioritize “what you play” over “how you play.”  There are no playing exercises that can bring an embouchure to this degree of refinement if they are performed with an uninformed mouthpiece placement (especially if done before setting the embouchure), or if played with poor weight distribution, and without an awareness of this ideal.  However, with a good starting position established first, those more traditional playing exercises take on a new life, as the player learns to maintain this form (with the same coordinated muscles that made the position) while practicing long tones, slurs, scales, arpeggios, tonguing exercises, etc.  Then those exercises can reveal what might have been missed during the initial setup, and/or when, where and why there may have first been a departure from form.  Practicing in this way takes the player to the heart of any fundamental problem and provides a clear path to the solution.

There are some who say you should never change a student’s embouchure, but most original embouchures were arrived at by beginners, and in my case, I would not want to put my career in the hands of an eleven year old.  There are others who say that the student should find what works best for them…what feels most “natural” and comfortable, but those feelings are usually based on a limited experience, and usually involve unfocused embouchures.  I can’t imagine any setup more comfortable than the air cushion created by a well aligned, well sealed embouchure with good air support.

    I’ve been playing trumpet for more than 50 years and this is the most informative and helpful writing on embouchure, airstream, jaw position, and lip/tongue function I’ve ever seen. Makes me want to try some things on my horn and I would but it’s 3 AM!

  2. says:

    I play mellophone with a Hammond 6MP (cup mouthpiece) and french horn with a Vincent Bach 16 (funnel mouthpiece).

    Would the techniques posted here help with those instruments, or is this just for trumpet?

    • bobgillis says:

      This “blueprint” would definitely apply to you and your current equipment. Mouthpieces and teeth formations are variables that can be adjusted for with the correct jaw position, horn angle, mouthpiece placement, mouthpiece weight distribution and the way the embouchure is formed and held, plus a relaxed upper body, throat and tongue…especially when all of these elements remain in balance after the air is added. The results you experience will depend on how much correction is needed, and how well you can adhere to all of the principles. Most brass players share many similar problems, and will notice improvement with every corrective measure taken. I hope that helps! Bob

      • Scratch Gobo says:

        When I form my lips like figure C, I can’t play low notes, and have trouble controlling my pitches, but my tone is loud and clear. Is this a common problem? And how should I fix it?

        • bobgillis says:

          You have taken the first step, which reveals how easy it is to play in the upper register. The control will come with more control of the airstream…for an efficient embouchure is very sensitive to air. The low register often does not play at first because of too much tension at the center of the embouchure…usually from too much mouthpiece pressure (the embouchure is also more sensitive to that as well), weight distribution that is still favoring the top and/or center, and/or squeezing the lips at the center (often by bringing the bottom lip up), rather than by “scissoring in” towards the center. The lip line needs to be down and centered between the teeth aperture so the top lip is better exposed to the moving air. There should only be gentle contact at the center, leaving it the point of least resistance…even with a very small hole…all the while the throat is very relaxed and open, and the airstream is flowing. Be patient and don’t force a note to play or let go of the position (even if there is no sound at first)…stay relaxed and focused, for the skills you are learning will develop much more than the lower register. Check the related posts for more info, and good luck! Bob

    This is the best article on embouchure I have ever seen! It’s been a couple of months since I read it, and my endurance, tone, articulation and range improved dramatically. Thank you and be very happy in your life!

    • bobgillis says:

      Congratulations on your success! You’re another great example of the kinds of results that can be achieved when the physics are understood and implemented.

  4. Michael Lee says:

    Amazing! I am not a pro trumpeter but am a serious hobbyist for over 20 years. I tell you that this article plus the other three, titled “The Landing”, deserve some recognition from the professional trumpet community. I would seriously recommend these articles for doctoral consideration. Seriously! Congratulations! And many thanks to your unselfish dedication for the benefit of the brass players in general. I’ve made a color printout and am planning to read it over and over until I understand every detail of it. I wish I live close to you and I could get some help from you. I will write more later.

    • bobgillis says:

      Hi Michael,
      Thanks so much for your kind words. I’m happy to hear that you will be studying this “blueprint,” for developing an awareness of How we play is a crucial step for both problem solving and self growth.
      I wish you all the best,

      • Michael Lee says:

        Hi Bob,

        I consider myself very lucky in discovering you website since I am in the process of a major embouchure overhaul. My main problem with the current embouchure has been lack of endurance due to the fact that the lips, especially the top lip, are being stretched out and not providing enough cushion for the mouthpiece pressure. Here’s a question I’d like to ask you. When a strong air stream passes through the tiny aperture of “bottom lip hugs” formation, will the interior space between the inverted (or rolled-in) lips and the teeth be filled with air like a sail catches air and is inflated? If your answer is “yes”, then this air filled gap might provide the necessary cushion for the mouthpiece pressure and greatly increase endurance. Thanks in advance.


  5. bobgillis says:

    Hi Mike,

    There is definitely a cushion created by the combination of the inverted “M” position (when the Lip Line is centered between the 1/4″ teeth aperture) and a relaxed and flowing airstream. Although air will fill the entire intra oral cavity, we try to keep the lips “hugging” right against the teeth and gums. The more the lips give out (which could increase the space between the lips and the teeth), the less compression and response (think of Dizzy Gillespie in his later years). The more the “sail” of the hugging action inflates, the less the boat moves. That cushion is nice to have, but a focused lip aperture and proper air support will reduce the need for pressure, which is what will increase your endurance far more.

    I should add that you must also consider how the mouthpiece weight (pressure) is distributed. The “scissor action” helps create a shape at the corners that protects the center of the embouchure, leaving it more free to vibrate. For the same reasons, the pressure should be lighter on the top lip. If the weight distribution is not correct, it will be harder to maintain the formation, which then increases the reliance on weight, invites even more mouthpiece pressure, and decreases endurance.

    I hope that helps!


  6. Thank you for sharing your info. I really appreciate your efforts and
    I am waiting for your further post thank you once again.

  7. Brian Gilman says:

    Hi I am having problems with my embouchure, a case of strep ripped out the tissue in my mouth 10 years ago. even though I have long since healed, now when i play trumpet I tend to leak out of the right side of my mouth. it seems I can’t close it tight enough. When I reach the higher notes I buzz and even spray out of the side of my mouth. I can stop it by putting my finger on it but then I cannot play too well. how can i fix or compensate for this?

    • bobgillis says:

      Hi Brian,

      My sincere apologies for not responding sooner…somehow your question slipped through the cracks, and I only just now discovered it. I was sorry to hear about the loss of tissue in your mouth, but my guess is that when you returned to playing after that, the mouthpiece pressure and/or placement (in regards to the distribution of its weight on your embouchure) may have been used to compensate for that muscle tissue loss and any inherent weakness. Even though your body could have healed up afterwards, that mouthpiece weight has remained, closing up the center of your embouchure. The air must be able to flow in order to produce sound, and so the air had to find another way to get past your lips…hence those leaks. You could develop a stronger “Scissor Action” at the corners, but that action alone addresses the symptoms more than the cause.

      I would read my recent post “Teaching an Old Dog New Tricks” and the related articles at the bottom for more details (including “Support from the Sports Medicine and Physical Therapy Fields”), but essentially you have to first make sure that the embouchure is formed correctly (without the horn), and that the point of least resistance is at the center. Then maintain that balance as you blow (still without the instrument), making sure the balance is not disturbed, giving the muscles a chance to develop correctly. After correctly exercising the formation in this way, you can next bring the horn in very close to the lips, still without making contact, just to check that when it does land, the weight will be properly distributed, and that the lip aperture is still centered, relaxed and focused. You may have to start over again if you notice the lips losing their formation, but if all is well, while keeping the air flowing, gently make mouthpiece contact with the embouchure and see if a note plays, making sure you are not using poor mouthpiece weight distribution, or old embouchure habits to produce the sound…in other words, maintain the new balance you have learned.

      It would be better not even to make a sound at first if everything is not yet in place, giving the improved formation a chance to develop, and for that image of playing to be clarified in your mind, than to carelessly just begin playing notes.

      Like I said, there is a lot more information in those articles, but this hopefully at least will give you an idea about the root of your problem, and a start towards correcting it.

      Take care,

    Thank you very much, Bob!! I’m a pro trumpet player and I find this esential information very helpful for me with my own research and for my students for embouchure understanding. I’m from Spain. Thanks again and congrats!!!

  9. Jerome says:

    Hi Bob,
    Very instructive reading!! I have a question about the “C” image where the “roll-in” shape gives a larger red lip part exposed to the air. I have thin lips: you can’t see the red lip part when I have a closed mouth. So if I want a larger red lip part exposed to the air flow, I have to do a “roll-out” position. In this case the vibration is more free and the center is more relaxed than with roll-in position. Is not the good way in my case? For you the good way is the roll in position like the C figure? Thank you for your help

    • bobgillis says:

      Hi Jerome,

      If you have something that works for you, why change it? However, if you would like to improve certain aspects of your playing, you should always consider where your current fundamental approach may be failing you. The hugging aspect of diagram C is only one part of the Scissor Action, and of the entire playing system. Also remember that those diagrams are very crude, and show a very general action of the embouchure muscles, without representing every possible type of lip tissue. If your “roll-out” position continued to roll-out more and more during your playing, it would eventually lose its functionality, so consider that some of that hugging action generally illustrated in Diagram C would keep your current position from going too far in that direction.

      Thanks for sharing your question, Jerome…you brought up an important point, and stimulated discussion on a key point of embouchure formation.

      Good luck!


      • Jerome says:

        Hi Bob and thank you for your answer.
        What I wanted to say is what is the more important: the roll-in of your C diagram, or to have a large red lip part exposed to the air flow to obtain a better vibration, a good sound and a better endurance. In the second case, maybe you have to do a (little) roll-in or a (little) roll-out? It’s depend of the extern part of your lip? Is it the “good” theory? Of course you have to avoid a mouthpiece full of lip or the space between teeth full of lip lol.
        When I speak about roll-in roll-out it’s maybe what it seems to be for your brain but in fact it’s just few mm from the “M” position in one sense or the other?
        It’s like for the corners. When the pressure increase I think that my corners are getting closer together but in fact in the mirror they don’t move. It’s just a sensation but it’s to keep the aperture centered and opened. Same thing for my upper jaw: I think it goes to the back (it’s impossible!) but the lower jaw goes to the front. With that, the teeth stay on a same line.
        All that, is a little bit subjective, isn’t it? lol

        • bobgillis says:

          Thanks for sharing your thoughts, Jerome. I think we would all agree that there are many opinions as to what the “best” way of playing the trumpet is, but the fact is, we are all subject to the same physical laws. The words we use for terminology often mean different things to different players, and can be vague. I come from the camp that believes we have to be as well versed in the design and assembly of the human part of our instrument as the trumpet or mouthpiece designer and builder is with the metal parts. I can’t really review all of the information I’ve tried to present in this blog with this brief response, but would offer this: You have to experiment with any idea that has merit, and be as careful as you can to make sure any experiment is done under the most controlled conditions, so you can really determine why something works or does not work. If done properly, your own experience will reveal the answers you seek. Awareness is critical. The questions will continue to rise as long as you sense limitations in your own playing and desire to improve, and so you must continue to address them in the same methodical way.

          I wish you all of the best, Jerome!


  10. Douggerr says:


    Referring to your side views of the teeth and lips, what would you say about my ingrained embouchure configuration, which is similar to “D”, except that the teeth gap is a little wider and the bottom lip comes up and inward, over the bottom teeth? I probably developed this habit from too much mouthpiece pressure pushing the meaty part of the bottom lip up and over the bottom teeth. Should I endeavor to correct this? I am working on the scissors action and reducing mouthpiece pressure, but trying to correct the bottom lip seems like it is a giant step backwards and is going to take a long, long time to accomplish.

    • bobgillis says:

      Thanks for your Inquiry, Doug. If I were you, I would definitely make some changes, but first it’s important to ask how you first developed those habits. We want to address the root problems, rather than trying to fix the symptoms. As you suggested, too much mouthpiece pressure can cause problems. Without actually seeing you play, I can only guess how they began, but I’ve seen what you have described many times, and can suggest a way out of your dilemma.

      The heavy mouthpiece pressure was most likely caused by trying to play with too large a lip aperture to begin with (probably caused by not setting up properly before adding the mouthpiece, or carelessly placing the mouthpiece on the top lip first, in an effort to begin playing immediately). Inadequate air support (especially hard to come up with in that situation) only adds to the problems. This made it hard to focus and compress the air column, so in reaction, the body reacts by trying to accomplish this by various forms of misdirected tension (like more mouthpiece pressure, tight throat, squeezing the bottom lip up, etc.). This tends to disrupt the flow of air and plug up the center of the embouchure and inhibit vibration of the top lip, so the jaw recedes or opens in an effort to free things up. Then the body reacts to that misguided opening by squeezing the bottom lip up, and/or “tucking” the bottom lip into the mouth, over the bottom teeth edges ( (trying to establish some kind of focus and compression). Unless the mouthpiece is going into the mouth (which of course you would never do), it can’t push the bottom lip in there.

      I would begin with some preliminary steps that are done without the horn, but in front of a mirror. Start with getting the top and bottom teeth vertically aligned, and gently touching. Then slowly bring the lips together, meeting 1/8″ below the top teeth in an “M” position, trying to invert-hide the “reds.” Most people tend to squeeze the bottom lip up to get this inversion (and is why the lower register then becomes harder to play), but there are solutions to that below. This is not a playing formation, but with the teeth touching, you can’t curl the bottom lip over the bottom teeth edges. The only way your can achieve this lip inversion is with the hugging action. With the teeth touching, you become more aware if the jaw starts moving around. It must remain passively stationary.

      Then blow air gently (but steadily) through the center of this setting without letting the jaw open or recede, or the lips erupt out. With the teeth just touching and the lips inverted, there will be all lot of initial resistance to blow past, but rather than forcing things, the objective here is to learn how to release all unnecessary tension at the center without releasing the position.

      It’s amazing how easy this is once the coordination is learned. Practicing without the trumpet in hand keeps the attention focused on this important step, rather than trying to make a sound or music, which also speeds up the learning process. Divide and conquer.

      Next, place an unsharpened wooden pencil through the middle of this setting, with the pencil sticking straight out. The jaw will now have to open 1/4” (the diameter of a wooden pencil, preferably unsharpened). Always hold the pencil, so the lips or jaw aren’t closing the center. Blow again as above, but now maintain the proper teeth aperture too. One reason the teeth were touching originally was to keep the bottom lip from “tucking” into the mouth over the bottom teeth edges. Make sure to avoid this now as the teeth open. Continue to use the same muscles you used when the teeth were touching.

      Rushing these steps along (sorry!) for now, once that is working, learn how to gradually speed up the air, without getting tight in the throat, clamping or drifting with the jaw, or squeezing the lips together at the center. The embouchure is holding its position at the corners (like the way a string is held in place at its endpoints, to allow the center to vibrate freely). If this is working, see if they can do they same thing without the pencil (something I call “Focusing Air”).

      After many repetitions and mastery, next bring the trumpet up to your lips, as close as you can without touching them. At this point the urge may still be to “kiss” the mouthpiece, and/or recede or open the jaw more than that 1/4” aperture, but now you have the experience gained from the above exercises. The air will help to trigger the new feeling of embouchure and air working together in a relaxed yet efficient way (I call this step “No Weight Blowing”). If you can ignore the mouthpiece and can concentrate on maintaining the new feeling, the embouchure and air working as a team will then learn how to translate this to your playing. You can also practice music this way…the counting, fingering, and articulation. Since the mouthpiece isn’t yet touching the lips, the attention is on the form, rather than the sound. However, listen to the sound of the airflow, making sure that it doesn’t sag. If the air sags, it’s likely that the lip formation will too.

      Long tones follow that step, and the old habits will still want to kick back in, but just cycle back and forth with Fighting Air or No Weight Blowing. These exercises are also great ways to rejuvenate the lips if they are getting tired.

      By prioritizing sound over form, you are creating a strong mental image, and giving the correct muscles a chance to develop before trying to play. With a more consistent way to focus air, the body is less apt to come up with its own knee jerk solutions, which only spawn unwanted side effects in a vicious circle.

      I hope that helps!

      Take care,

        I have a rather pronounced Cupid’s bow and overbite
        I am always fighting these
        Although trusting the air and embouchure etc is important
        It is hard to trust my set up
        That is my plight !
        I can play 2nd in any big band – lead never !
        Thanks again
