Here’s a neat site that has a number of classic jazz solo recordings played back at half speed. It’s called Half Speed Jazz. The recordings aren’t really at half speed, they are retained at the original pitch. And then it’s played at the original speed.
Someone who isn’t a jazz improviser might wonder why recordings slowed down to half speed are helpful. Transcribing classic jazz solos is considered an essential part of learning to improvise well. Particularly when you’re a beginner at transcribing, it’s helpful to be able to slow down the recording to pick out individual notes.
While it’s much more convenient to simply get a hold of software that will do this for you, I found it interesting to take some time to listen to the slowed down recording and then the original speed. Different things about the solo stuck out to me, depending on which speed the playback was. It’s also striking how hard some of the solos swing at half speed.
Having a comments section here in my blog is sometimes a double edged sword. I do feel that one of the most powerful tools the internet can be used for is the ability for us to question and discuss things with people that we would not otherwise get the opportunity to interact with. The flip side of that benefit is that online discussion often breaks down and has the opposite effect that we want. I see this all the time on brass fora. Too often folks offer advice to someone they have never seen or heard play before. Sometimes I question whether the confidence they seem to have about their responses are unjustified. Sometimes those folks don’t (or can’t) demonstrate even basic competence. Joey Tartell has noticed similarly and written about this phenomenon in his blog post, Nuance.
I do not argue with these people. In fact, I choose not to engage with them at all. What I’d like to discuss today is what’s missing from so many online discussions.
One common pattern Tartell notes is the false dichotomy, when a disagreement is framed as either all or nothing, black or white, without acknowledging that there can be a continuum of possibilities and shades or gray in between. My posts a while back about the relative value of metronome practice is one example. The ensuing discussion between blogs and in the comments section kept getting reduced, in spite of my efforts, to “metronome practice is bad versus metronome practice is good.” There was little room to discuss the nuance between. Another similar pattern is the assumption that when someone says one thing is good, that means the author is calling something else bad. The metronome discussion is another good example. Just because I find a metronome a good practice and teaching tool doesn’t mean that using other approaches are bad.
Tartell lists several suggestions for how to make an online discussion more fruitful. Here is his basic list, but I suggest that you go over and read his elaborations on his original post.
Decide what’s important to you.
Will getting involved do any good?
Stick to the subject at hand.
Realize that other people could have something important to say.
I’ve been fascinated by harmonic singing for a long time, ever since I first heard that it was possible for singers to produce more than one pitch at a time. There are different musical traditions that make use of harmonic singing, but to me the most interesting is the traditional music of Tuva. While I’m no expert, my curiosity led me to explore the techniques and taught myself the basics.
Mike Ruiz is a former colleague of mine. In addition to being a fine classical pianist, Mike is a physics professor at the University of North Carolina at Asheville, where I used to teach in the music department. I’ve enjoyed picking his brain in the past about acoustics and recently Mike asked me to assist him with some physics education articles and videos he was producing. He was interested in trombone multiphonics, but in the course of our conversation I mentioned the harmonic singing. The resulting article is called Tuvan Throat Singing and Harmonics. The abstract can be read here. Here’s the video abstract.
At the same time that I demonstrated the Tuvan throat singing technique for Mike I also demonstrated trombone multiphonics as well, including some techniques that incorporated the throat constriction used for harmonic singing. When I put together trombone multiphonics with harmonic singing I have been able to come up with some interesting sounds that are similar to what you might hear on a didgeridoo. If and when that paper gets published, I will post about it here too.
Here’s a neat video I came across by Tyley Ross, a voice teacher and vocologist from New York City. He demonstrates four distinct vocal styles while in an fMRI to show how his vocal tract changes for each style.
I am always excited when musicians and pedagogues investigate the science of how we create musical art. It’s easier to do with voice than with brass instruments, since there’s not external instrument that needs to go into the MRI. Because the voice is also an area that medical science specifically studies also, we happen to know more about how sound is produced when singing.
I was somewhat surprised by how open the soft palate was open on the operatic style compared to the rock style. It’s pretty cool to be able to look inside the body and see what’s going on.
Learning to play any musical instrument, including trombone, is an inherently “knacky” experience. So much of what you need to do to be successful involves trying something a bunch of times, making small physical adjustments each time, until it clicks once. Then there’s a lot of trial and error trying to make it work that way consistently. Each musician’s playing sensations are going to be different and be influence by not only anatomical differences, but also the history of how they played before and their personal beliefs and biases.
This is undoubtedly why a lot of brass pedagogy involves teaching musical artistry first and teaching technique through modeling and metaphor. The end result, however, is that there is less consensus about what good brass technique is and how to achieve it. We have a tendency to look towards so-called “natural players” for advice, who may be the least qualified to tell us what’s actually physically happening when performing.
Couple this with a persistent culture of ignorance in brass pedagogy. It’s normal for some brass teachers to discourage folks to analyze their playing. It will to lead to “paralysis by analysis.” If you do, you won’t see the forest for the trees. Imitate the sound you want and you’ll learn it, just like you learned to talk as a baby. If a centipede had think about how it walked it would get nowhere. Don’t think, play.
I find this attitude confusing. Why would a teacher disparage questioning and thinking? That’s the message it sends. And that’s what those students end up passing on when they become teachers.
The other side of this coin is the vast amount of pseudoscience you can find in brass pedagogy. Part of this is due to literal interpretations of analogies and over reliance on fallible playing sensations. A lot of it is due to us over estimating what we actually know. At its heart, it’s a lack of scientific literacy. Trombone teachers usually aren’t scientists, but we tend to misunderstand what science actually is and mistrust it. It’s often seen as a non-overlapping magisterium with both music and teaching. If the science suggests something we’re teaching is wrong, that’s just an egghead in the white tower who hasn’t spent enough time in the trenches.
Science isn’t a collection of disciplines like anatomy, physiology, kinesiology, and acoustics, although those disciplines might inform how we teach trombone. Science isn’t about acquiring facts either, although they might help us too. At it’s heart, science is about exploring the limits of what we know. It’s about testing a hypothesis and challenging assumptions. And it also happens to involve a lot of creative thinking, much like in music.
Superficially, we probably already do this in our instruction. We try out something with a student and assess whether it worked. We test it out for a while and then try something else. If we can’t find the answer is a resource we have, we create one specific to the student. When something works for one student, we try it out with another student and see what happens. Over time, we can develop a large repertoire of analogies and methods and get a good feel for when to try one and when to try the other.
However, we sometimes confuse this for science. Science recognizes that the nature of that experimentation we did in our teaching studio is inherently biased. It’s too easy to simply confirm what we already believe, rather than learn something new. You can’t look for evidence that your hypothesis is right, you look for ways to falsify your beliefs. If you ideas withstand that sort of scrutiny, then maybe you’re on to something. Brass pedagogy has long only looked for evidence to support our preconceived beliefs.
Herein lies the scientific method’s greatest strength. It is self-correcting and always looking to learn more. Science-based pedagogy has been more popular in other disciplines (e.g., athletics) because brass pedagogy hasn’t been as good at fixing our old mistakes. We routinely revere long dead pedagogues, now and then referring to their texts as “bibles” and former students of those teachers as “disciples.” This isn’t an attitude conducive to change.
There is good science being done on brass pedagogy. Our understanding of both the acquisition of motor skills and the specific physical process of playing the trombone is better understood now than it was when I was a student. The exciting part is that access to this research and the scientists who do this is easier than ever. What’s difficult is vetting the information into a correctly nuanced context. That takes some effort and should be an ongoing process. You can’t just look at what we know, but also question how we know what we know.
The following rant was inspired by a Trombone Pedagogy Facebook group thread started by a teacher who was wondering how to help a young student who was playing with his lower lip predominant. The teacher was asking for advice on how to correct this embouchure. My rant below is in response to many of the ensuing comments. I will be paraphrasing instead of directly quoting, in part because these responses are so common and don’t really need an attribution for context.
First, a little background on what an upstream embouchure is. All brass musicians, regardless of what they might think they are doing or should be doing, play in such a way that one lip or another predominates inside the mouthpiece. When the upper lip is predominant, most common, the air stream passes the lips in a downward direction.
Most brass players have an embouchure that is similar, although the amount of upper to lower lip may be different. A minority of brass musicians, however, do the opposite. These players place the mouthpiece closer to the chin and because of the predominance of lower lip the air stream gets directed upwards.
With that basic understanding out of the way, I will get into addressing some of these typical comments.
Change the mouthpiece placement. That student will thank you for it later.
While it does happen that students will adopt an upstream embouchure when they should be playing downstream, it’s much more common for these “low placement embouchure type” players to be playing that way because it is the most efficient embouchure type for their anatomical features. Before you change the mouthpiece placement you need to address issues with embouchure form, breathing, tonguing, posture, etc. Usually if you correct those other playing characteristics the embouchure will function better.
Sometimes you can disguise those other issues by changing the mouthpiece placement, but that’s only covering up the real problems the student is having. Before the embouchure form is developed properly, for example, you just can’t tell where the best mouthpiece placement is for a particular student.
That student should try another instrument instead. Has he/she considered a woodwind instrument or vocals?
I tend to avoid encouraging a student to change to a different instrument if they’ve expressed an interest in their brass instrument. Sure, maybe some folks will take to another instrument and never look back, but that’s a solution in search of a problem. If you need more bass clarinetists in your band be honest about why you are encouraging the change. If you’re suggesting the change because you don’t know how to help that student, then do some homework and learn. This is your responsibility as a teacher (or even as someone giving advice on the internet). Ask questions. That’s what the Facebook Trombone Pedagogy group is for!
Upstream players are players who have a protruded lower jaw or an underbite. That’s what makes them upstream.
Players with an underbite almost always play better with an upstream embouchure, but that alone isn’t going to make their embouchure upstream. There must be more lower lip inside the mouthpiece in order for their embouchure to function upstream (Caveat – Sometimes lip texture comes into play. It’s rare, but you might look at an embouchure from the outside and think it’s one direction but when you look on a transparent mouthpiece the lip position seem flipped. My feeling is that moving the mouthpiece placement to a more appropriate placement can often help).
I don’t have a way to post the video clip (nor have I obtained permission), but my teacher, Doug Elliott, made a film in the 1980s called The Brass Player’s Embouchure. In this film he shows a trombonist with an underbite, but with a mouthpiece placement that was close to the nose and it function downstream. Moving this player’s mouthpiece placement so that it had more lower lip inside worked better.
And not all upstream players will have a protruded jaw position anyway.
Look again at the downstream embouchure example I posted above and note his jaw position. Jaw position while playing will be an influence, but doesn’t actually make a player upstream or downstream.
Also worth considering are Donald Reinhardt’s embouchure types. While I prefer to teach and communicate using different terminology, he did make note of players with particular jaw positions while at rest compared to playing. For example, he classified players with a natural, even bite.
Such brass musicians will almost always need to place the mouthpiece either very high (close to the nose, downstream) or very low (close to the chin, upstream). It might go either way, and for players like this it is sometimes quite difficult to tell which way it might go. Even if that is a very accomplished brass musician (read through what Brad Goode has written about figuring out his embouchure type).
That’s an [insert one brass instrument type here] thing. Those of us who play [insert other brass instrument type here] can’t/shouldn’t play upstream.
After 20 years of studying brass embouchures on all instruments intensively, I’ve come to the conclusion that while there are some differences that the size of the mouthpiece causes, it’s only a matter of scale and that the same embouchure characteristics are found on all the brass instruments.
Now it’s easier to find examples with trumpet players for a couple of reasons. Consider that the larger the mouthpiece, the more likely that the chin or nose will get in the way of placing very high or very low. A trumpet mouthpiece, on the other hand, allows much more leeway for getting the most efficient ratio of upper to lower lip for the particular player. That said, horn players are much less varied, which I believe is due to the adherence of a particular pedagogue’s advice as well as a comparative lack of players who are self taught and simply do what works instead of what is commonly taught.
That’s an [insert musical style] thing. It won’t work for [insert another musical style].
It’s only good for [high or low register playing]. It won’t work for [low or high register playing].
Embouchure type is influenced by the musician’s anatomical features, not playing style, instrument choice, or musical genre.
When you place the mouthpiece with so much rim contact on the upper lip, it isn’t free to vibrate and causes problems.
Both lips do vibrate in conjunction, but they do not vibrate with equal intensity. The predominant lip inside the mouthpiece vibrates with greater intensity. Brass embouchures appear to be sort of between a double reed phenomenon, where both reeds vibrate with equal intensity, and a clarinet reed, where the reed vibrates against the surface of the mouthpiece. For a brass embouchure to function efficiently the lip that has more rim contact (the upper lip in the case of the upstream brass musician) will function somewhat like the clarinet mouthpiece while the other lip (lower lip for upstream embouchures) is more like the reed.
This isn’t arm chair speculation. You can see it in Lloyd Leno’s film quite easily. Here’s part 1 of 3, but the link is to the entire playlist.
If you watch the entire film you’ll also be able to note some downstream trombonists in the film who place the mouthpiece with a great deal of rim contact on the lower lip. For some reason this isn’t as widely discouraged, even by the same players who make this argument when it concerns an upstream embouchure.
I am an experienced teacher and performer and I have never come across a successful upstream player.
My first response to this is that you’re probably not qualified (yet!) to identify one when you see it. Furthermore, if you don’t consider embouchure types to be a useful pedagogical tool, then you’re simply not going to look for them – even if you know what to look for. So many teachers seem to think that by watching a player blow air, free buzz, mouthpiece buzz, talk, whatever, that you’re going to be able to determine a player’s embouchure type. You can’t. Or at least I can’t and I doubt you can.
I’ve gotten to the point where I don’t need a transparent mouthpiece to type most players’ embouchures, but I know the limitations of this and will grab a transparent mouthpiece when needed. Simply put, the most accurate method of typing a brass musician’s embouchure is to look at how they play while playing the instrument into a transparent mouthpiece. Rim visualizers can give you important clues, but the lack of resistance and the reflection of the standing wave back to the lips (as well as other factors) come into play and make a rim visualizer less accurate.
To my knowledge, no one has yet conducted a robust enough study to determine the percentage of upstream players, but by my best guess I would say around 10%-15%. That’s a sizable enough minority that anyone who takes the time to actually look for upstream players among your students and performing colleagues will find them. If you’re not seeing them, you’re probably not looking.
That said, an awful lot of teachers who should know better make a big deal about “correcting” an upstream embouchure when they see one. I get emails and private messages all the time from folks describing this situation. Particularly for teachers who work with older students you’re going to find fewer upstream students because they get “weeded out” by well-intentioned, but ignorant teachers. Either those students quit brass out of frustration or they play with less success than they could because they had their embouchure changed to a less efficient one. I’m a good example of the later, although I was never changed to downstream. I was instructed from the get go to play downstream. Which leads to:
We should teach what’s most common because that will have the best chance of success.
There is some logic to this, but in the case of mouthpiece placement I don’t even think we should talk about it with beginners. Teach embouchure form, not mouthpiece placement, and most of the time I’ve found the student will naturally gravitate to the best embouchure type for his or her anatomy. When it doesn’t, then it’s time to intervene, but this correction needs to be an educated choice that eliminates difficulties in embouchure form (or breathing, tonguing, whatever is influencing the student’s embouchure in a negative way) first.
I am an experienced teacher and never have to consider a brass embouchure type. It’s unnecessary and even makes things worse!
It does take some effort to learn how to type a brass student’s embouchure and use it to make embouchure corrections and design a course of study and practice that will work best for the individual student, but it’s not rocket science. If you found studying music history and music theory to inform your brass playing in a positive way then you already understand how taking the time to learn about different related topics is useful. If embouchure analysis is making things worse it’s because the analysis is faulty in the first place. Learn how brass embouchures actually function and apply what you learn, adjusting as you need to. And if the student is analyzing their embouchure technique at the wrong time, help your student learn to focus on one thing at a time while practicing for a bit each day and focus on the musical expression the rest of the time.

Here is another TED talk, part of a playlist on “Practice Made Perfect.” The overall theme of these videos are improving learning. In this talk, Angela Lee Duckworth discusses the importance of grit to learning.
Leaving a high-flying job in consulting, Angela Lee Duckworth took a job teaching math to seventh graders in a New York public school. She quickly realized that IQ wasn’t the only thing separating the successful students from those who struggled. Here, she explains her theory of “grit” as a predictor of success.
So far, the best idea I’ve heard about building grit in kids is something called “growth mindset.” This is an idea developed at Stanford University by Carol Dweck, and it is the belief that the ability to learn is not fixed, that it can change with your effort. Dr. Dweck has shown that when kids read and learn about the brainand how it changes and grows in response to challenge,they’re much more likely to persevere when they fail, because they don’t believe that failure is a permanent condition.
I find it interesting that Duckworth also studied teachers in her research. She not only looked at which new teachers in a tough neighborhood would stick it out, but also which teachers would show more successful outcomes for their students. This tells me that grit and the growth mindset are also characteristics of good pedagogy, as well as qualities we want to encourage in our students.
I’ve been meaning to post about these videos for a while. Matthias Bertsch, who has conducted a lot of research into how musicians perform on their instruments, has posted a couple of videos on YouTube that look at the tongue motion of different musicians. He attached sensors to the tongue and was able to model how the tongue moves when performing different things on trumpet and clarinet.
Just last week I posted about Doug Yeo’s experience playing trombone while inside an fMRI scanner. Bertsch’s trumpet video above showed some of the clips from much older research looking at the tongue motion of brass players using fluoroscopic techniques, which unfortunately exposes the test subjects to radiation and really isn’t an ethical use of that technology knowing what we do now about the dangers of such exposure. The motion sensor analysis and fMRI studies are significant improvements and hopefully as the technology gets better (and cheaper and easier to use) we will see more research conducted into how brass and woodwind players play their instruments. Taking the guess work out of what correct technique is and what a student is actually doing has the potential to significantly improve how we teach music in the future.
