Embouchure 101Notes on the basics of a well-formed embouchure John EricsonA version of this article was published in the Texas Bandmasters Association Journal 4, no. 2 (December, 2002). 1. Mouthpiece placement
For as long as horn method books have
been written horn teachers have advocated using a mouthpiece placement of 2/3
upper lip and 1/3 lower lip. Ideally the horn produces a mellower, richer,
darker tone than any of the other brass instruments. An element of this tonal
color is certainly driven by the embouchure being generally more relaxed and
puckered than the embouchures used on other brass instruments. This slightly
more relaxed, puckered position of the horn embouchure emphasizes the fleshy
mound in the center of the upper lip, and this in turn favors a higher
mouthpiece placement.
Besides the darker basic tone production
of this setting, a higher proportion of upper lip is also beneficial in playing
the entire range of the horn, which is almost four octaves. Too little upper lip
will not allow for production of the lowest notes of the horn with a full tone
without making major shifts of placement.
The basic setting should be the same in
the high, middle, and low ranges of the horn. Often students don't place the
mouthpiece as high as they think that they are actually placing it, something
closer to 50/50 than really 2/3 upper lip. You ideally want the mouthpiece to
rest over the top of the fleshy mound in the center of the upper lip.
The most ideal mouthpiece placement is actually fairly easy to define for most players. One simply needs to wet their lips, place the mouthpiece on the lips, and let the mouthpiece slide into that position over the mound of the upper lip. Another way to think of this is to "hang the mouthpiece on the hook" of the upper lip. Either method accomplishes the same thing and will almost automatically give a hornist a good, natural mouthpiece placement for the horn, 2/3 upper lip and 1/3 lower lip. A related question is does the
mouthpiece have to be centered left to right? The short answer is no. The face
and teeth may dictate an off center placement, but this is of no real concern if
the player feels comfortable and natural with the placement and can form a good
aperture. There are many fine professional players who have slightly off-center
embouchures. But it should be added that if you play off-center with dry lips
you might in fact be forcing the placement into an unnatural placement. See the
following section
2. Wet (moist) or dry lips
Closely related to the topic of mouthpiece placement (above) is that of playing with wet or dry lips. The eminent horn teacher Philip Farkas in his classic treatise The Art of Brass Playing estimated that approximately 75% of professional brass players play with wet (or moist) lips, and I would add that it could be argued that the percentage is even higher among fine horn players. The primary advantage of wet lips is that the mouthpiece is free to move around somewhat and find its best, natural placement on the lips when first placed on the lips. This freedom of movement is also helpful in making large register changes, as the mouthpiece is not "stuck" in one position. There is no obvious disadvantage to playing with wet or moist lips for the horn player. Playing with wet or moist lips is especially important for the beginner on the horn, as the mouthpiece will be free to settle into its most natural position over the fleshy mound on the upper lip. Even for advanced players the topic of lip moisture is very worth considering, as on dry lips the mouthpiece can easily get “stuck” in a position that may feel normal but is nevertheless not necessarily the ideal setting where the tone will be the fullest, where the lips are free to vibrate in their most natural manner, and where you can play easily in every register. Finally,
mouthpiece rims plated or made of different materials will feel relatively more
or less slippery. While a silver-plated finish is the most widely used, gold is
also popular and some players prefer plastic or nickel silver. In the “old
days” some players even used raw brass rims, although this is recognized today
as not generally speaking being a good idea for health reasons. In any event,
there is no one ideal material for a mouthpiece rim and each one will alter your
perception of how the rim feels on your lips.
3. The function of the lip muscles
While perhaps an oversimplification, a way to visualize how we form a brass embouchure is to imagine that there are basically two groups of muscles at work. The first are those muscles that bring our lips to an extreme pucker, such as would be used to whistle--the muscles around our lips. The second group are those that bring our lips to a smile--the cheek muscles. Either group, working primarily by itself, can form a brass embouchure of sorts. Muscles can only contract or relax. When you pucker the cheek muscles relax while the lips contract. When you smile the cheek muscles contract while the lips relax. To form a correct brass embouchure the actions of smiling and puckering must be combined and balanced in a "tug-of-war." The best horn (and brass) embouchure would be one that finds a balance between the two extremes; Farkas called this ideal a "puckered smile." A large problem for brass players in general is often too much smile in the embouchure. This is a problem because this type of embouchure requires the lips to be pulled thin by the cheek muscles, and this leaves the lips prone to injury, will add a distinct "edge" to the tone, and cuts down endurance. A more puckered embouchure is naturally "thicker" in the area where the mouthpiece makes contact and provides for better endurance and tone. A bright basic tonal color on the horn is often related to too much "smile" in the embouchure, and it is not uncommon for this to also creep in when approaching the top register of the horn in an effort to reach the notes. The corners should remain the same in all registers; if the corners pull back in the high range this is an issue that should be addressed. While too much smile is not uncommon, it is very rare to find a player who has too much "pucker" in their embouchure. But to visualize how to play with the correct balance it can be useful to intentionally pucker too much. One exercise I have found helpful is to take a pen and try to hold it straight out with your lips only. You have to pucker and be aware of the puckering muscles to do this successfully; if you use the muscles that you use to smile the pen will droop. Avoid a bunched up chin when doing this
exercise. The bunchy chin is always a problem if encountered. See section 4.
A final related point has to do with
movement around the lips--the type of movement that you can see when playing
passages of music when looking at your embouchure in the mirror. An embouchure
with less overall movement between notes is better, as it is a more efficient
embouchure. A small amount of movement is not a real problem, but you do want to
be aware of and control large movements around the embouchure and lips as for
the most part these are extraneous movements.
4. The lip aperture and the chin The formation of the lip aperture is very closely related to the way one uses the cheeks and lips. Inside the mouthpiece the lips form an opening roughly the shape of the opening of a bassoon or oboe reed. If the embouchure is in a position that is too puckered or contains too much of a smile this ideal lip aperture shape will be distorted and tone will suffer. Ideally, a good lip aperture can be formed without the mouthpiece, in a manner where the air stream can flow straight out the mouth. Most often the aperture, if a problem, will be too flat due to either too much smile in the embouchure or to the chin being bunched up. The chin should be flat--if it is bunched up this is a sign of a serious embouchure problem that must be corrected. What happens is by bunching up the chin the embouchure will be too closed down because the aperture is being closed down from below and loses its proper shape; tone and volume will suffer a great deal with this type of setting. Another reason the aperture can become distorted is because of too much lip in the mouthpiece. Not only does this make the aperture flatter in shape but there is a characteristic roughness to the tonal color with this embouchure and often a lack of dynamic range. Only a little extra lip in the mouthpiece is the cause of this “clamping” condition and can drastically alter the resulting tonal color. In this situation playing with wet lips and a more open embouchure can make a great deal of difference on the instrument. A final reason the aperture can be
distorted relates to the structure of the lips themselves. See section 8 for a
further discussion of this topic.
5. Aperture control and the corners An important issue of playing in general and especially in the high register is aperture control. Proper aperture control will help not only the high range but will also help with accuracy in general. The aperture must be smaller in the high register than in the low register, and you want to practice in a manner that helps you to feel and develop fine aperture control. One method is to as you play visualize that you are controlling the muscles “inside the mouthpiece,” making the aperture smaller from the corners and keeping the same basic shape playing low and high. Visualize the relative size of the opening of a bassoon and a oboe reed, holding that basic shape. As this can be difficult to visualize, a more concrete method of thinking about aperture control, suggested by Fred Fox in his book Essentials of Brass Playing, is to think of the embouchure being controlled by two sets of muscles. One set is in the corners and is used to produce the sound "eeeeeeeeee" and the other set is in the middle of the lips and is used to produce the sound "mmmmmmmmmm." While this is obviously an oversimplification, aperture control involves the use of these muscles, especially the muscles used to say "mmmmmmmmm." The corners relate to the aperture in
the sense that they need to remain firm and retain the same basic position
playing high or low. A correct position is similar to the "mmmmmmmmm"
position. A horn player should be able to buzz on the mouthpiece to the top
notes of their range; if this is not possible, even if they are able to play the
notes on the horn, it is likely that they have too much smile ("eeeeeeeeee")
in the embouchure.
6. Mouthpiece pressure and playing
high notes
Moderate mouthpiece pressure is required to play any note on the horn; there must be a seal between the lips and the mouthpiece. However, especially during the warm-up, it is critical to not use excessive mouthpiece pressure in the high range. Only by practicing in this manner can real strength and proper form be developed. It is a natural and actually an effective approach to use more mouthpiece pressure to reach the highest notes of the horn. This, however, is NOT the ideal way to reach them. We should instead focus our attention on the muscles of the lips that are inside the mouthpiece, focusing the air stream very finely with the aperture, and using plenty of support. An interesting question to consider is "why does mouthpiece pressure help in reaching the high notes?" The reason is that the extra pressure makes the lip aperture smaller. Farkas gave the example of a doughnut, placed under a piece of glass. If the piece of glass is smashed down on top of the doughnut, the hole in the middle of the squashed doughnut does get smaller. Our lips are the same as the doughnut in this sense. As we press harder, the aperture gets smaller. The result is higher notes come out, but with a cost in relation to tone and endurance. It is critical instead to focus our attention on focusing the aperture by using the muscles of the lips without using excessive pressure. In other words, if the top notes don't come out well, you may just need to be patient, practice consistently, and build up the strength to play high without excessive pressure. Thinking "mmmmmmmmmm" really does get at what we want, especially when playing passages like slurred arpeggios. There is one final pressure related point that must be addressed as well; lateral pressure. This type of pressure is basically only an issue for horn and tuba players, as these instruments (typically) rest on the lap. Lateral pressure is a type of mouthpiece pressure that forces the mouthpiece up, down, or to the side. This is type of pressure is just as undesirable as straight pressure because it cuts endurance and thins the tone by forcing the lip aperture out of its proper, natural shape. This pulling or pushing most often occurs when reaching for the highest notes on the horn. Besides focusing on the aperture, for
hornists an effective way to work on a lateral pressure problem is to practice
standing, as it is more difficult to apply lateral pressure with the horn off
the leg. Lateral pressure can also be very obvious when trying a new leadpipe
that is only taped to the horn--practicing with a taped on leadpipe is a
practical exercise to at least be more aware of the problem.
7. The jaw and the lips
The jaw is too often ignored as an element in forming a high brass embouchure. The placement of the jaw is very important. The reason this is critical is that the placement of the jaw relates to the way the lips are used. For the majority of horn players the jaw MUST be pushed forward somewhat from its normal position at rest, so that the teeth are in line with each other (up and down), as though you were biting a sandwich (but not, however, pushed out beyond being even with the upper teeth). Another easy way to visualize this concept is to imagine spitting a watermelon seed out. You will not roll the lips over one another--the jaw will come forward a bit in a very natural way. A common fault seen in less accomplished horn players is that the lower lip is rolled over the bottom teeth, and the jaw is not pushed forward. This type of embouchure is for most players problematic. An easy exercise to check the jaw placement is the following: form an embouchure without the mouthpiece and blow. The air stream should go out at the angle of the instrument--nearly straight forward--not at a steep angle down the chin. Most sources on brass pedagogy agree that an embouchure where the lower lip is rolled over the lower teeth and the air stream flows at a sharp angle down the chin is not a well-formed embouchure. Blowing forward and down the center of the mouthpiece is the ideal. The angle of the mouthpiece has a distinct relation to the jaw position. As a general rule you should feel that the mouthpiece pressure is basically the same on the upper and lower lips. A little more pressure on the lower lip is of no real concern and can be a part of a well-formed embouchure (some teachers even recommend this), but more pressure on the upper lip could point toward problems, as this will cut your endurance. It is result of improper jaw position. Mouthpiece angle is also of special
concern if you change the position of your jaw from a receded to a more square
position--the mouthpiece angle may also need to be changed somewhat as well.
8. An exception to the rules: the
“teardrop” upper lip
The basic geometry of the lips and jaw described above holds up well for most horn players. There are some players however for whom this basic set up simply will not work well. A “teardrop” upper lip, an upper lip that protrudes somewhat into the mouthpiece and that even at rest appears to hang down in the middle, like a teardrop, requires a somewhat modified approach. With this type of embouchure essentially the lip aperture must be formed so that the air will flow at a downward angle below the teardrop. With this type of setup you are looking for the same basic aperture shape described in the previous sections but it that shape will be accomplished on a slightly different plane, directing the air stream more downward. In relation to this, for the “teardrop” upper lip to form a successful horn embouchure you will need to allow the jaw to remain more or less in its natural, receded position so that you can form the aperture below the teardrop. The air stream will in this case be directed more downward and the horn angled more downward as well so that mouthpiece pressure is even on both lips. This type of set up may also work for
players where this is not an issue. It is probably not the ideal, but at the
same time it is not something to change if all the major aspects of playing the
horn are working for an individual player. This is also to say, there is no
one-size-fits-all horn embouchure setup; a “square” setup that directs the
air stream forward is desirable for most players, but for some this setup is
simply unworkable as the upper lip will in fact obstruct the aperture in this
type of embouchure setup. If you in fact fall into this category, be sure to
practice at the full range of dynamics and be conscious to make the best
aperture shape and tone possible.
