Understanding Callet: The Wisdom Behind Superchops

Understanding Callet: The Wisdom Behind Superchops

A discussion by Richard Colquhoun explaining the Tongue Controlled Embouchure
for those who wish to develop informed opinions

Introduction:

Below you will find 2000 words explaining the fundamental teachings of Jerome Callet. The reason I feel this article is necessary is because as I browse the internet I repeatedly find negative comments about Superchops, written not by people who understand the system, but by people reacting to and jumping to conclusions about things that they have clearly not researched. I do not wish to convert or change the minds of people, but instead to present facts so that people can develop informed opinions about this brass playing technique.

On the surface Superchops (closely related to the Tongue Controlled Embouchure) is an embouchure technique for brass players that includes using the tongue in a way that may people find unusual. This, however, is not all there is to it. Superchops is the result of half a century of research, testing and teaching. The goals of the system are very clear and striving to achieve these goals, even without using the technique, should be of benefit to every brass player.

Within this article I use the term “Superchops” to refer to the research and teaching of Jerome Callet. “Tongue Controlled Embouchure“, and “TCE” refer to the work of Bahb Civiletti, who has developed the technique further through the addition of different articulations and exercises. Some people use the terms comparably so in the “Narrative” section below I do too. Unless specified I am not referring to any one of his books or videos that share the same name (but could represent different time frames in the method’s development).

Narrative:

Imagine that you’re a trumpet player. One day you are having a break between practise sessions and you sit at your computer with a cup of coffee. You load up YouTube and because of your previous trumpet-themed viewing habits you see something titled Tongue Controlled Embouchure in your suggested videos list. Not having come across this term before you unwittingly click and watch a video in which somebody tells you to bevel your tongue forward, block the airway, and spit into a stupidly small mouthpiece. Instantly you know this guy is a hack and browse on to something else. When you return to your trumpet this stupid idea is still playing on your mind and you give it a try. You can’t even get a sound out of your instrument this way and again you reinforce the thought that this is a dumb idea.

Some time later you are browsing the web for some information about improving your higher register and you come across a forum post about using TCE for screaming high notes. Within a few replies of this thread you see people saying things like “TCE gives you a really piercing bright sound, is that really what you want?”, “I tried that once and I could never get a good sound, the articulation was too messy”, or “I can’t believe people do this… what flawed teaching!” (These are all direct quotes taken from various websites).

The problem I see with this narrative is that you’ve not been presented with a balanced argument but rather had your opinion dictated to you by people who, most likely, don’t have any experience of learning from Jerome Callet, or know what the goals of this teaching actually are. If you’re still reading this then my hope is to clarify the situation for you. It’s worth pointing out here that I am pro-TCE and use this technique in my playing. However I do assert that despite the development in my own playing, this method and way of thinking is not for everyone and trying to learn it without a teacher and the proper books will lead to you becoming another internet hater. OK… here we go!

What Superchops is not:

Here are some common misconceptions relating to Superchops:

  1. Superchops is a high note technique. FALSE. This method is very efficient and requires little physical effort. When mastered it means that playing high notes is easy, but that is definitely not its purpose.
  2. Superchops gives you a bad sound. FALSE. Playing badly, whether it be overblowing, poor articluation, or simply a lack of balance between different aspects of your technique, gives you a bad sound. This is true of all techniques. If you switch to playing with another technique you will start out sounding like a beginner because you are a beginner.
  3. Superchops gives you a bright sound. The principal lesson in Superchops is understanding how a trumpet should sound. This is achieved by listening to examples of the best recorded players in history and identifying the common features in their playing. This, coupled with learning to identify problems in your own sound, teaches you to be dis-satisfied with anything other than making the correct trumpet sound.
  4. If Superchops is about developing a powerful embouchure with strong articulation, what if I want to play a nice soft melody? This is the one that bugs me the most. Contrary to popular belief, learning about trumpet playing does not eliminate ones ability to be a musician. This argument is like suggesting that somebody in a Ferrari is incapable of observing speed limits. Just because the car can go fast, it doesn’t mean that it cannot go slowly.
  5. You need a small mouthpiece to play with Superchops. FALSE. You can learn to play anything on any mouthpiece. I have learnt how to make a big sound with a small mouthpiece because Superchops is efficient, but I can still play on any mouthpiece I need to should I have to adjust my sound for different playing situations.
A little history:

I don’t wish to repeat the standard story about Mr Callet’s failed trumpet playing as a youth, and how that drove him to rediscover techniques from the past and create a modern embouchure system based upon these ideas, because you can go and read that somewhere else. I also do not believe that creating a mythology around this subject matter helps to make things clear.

Here’s the story how I tell it. In 1972 Jerome Callet released a book called Trumpet Yoga. In that book he describes how through practicing exercises that involve moving between an Einsetzen and an Ansetzen embouchure enabled him to develop the strength to consistently play notes in the extreme upper register with ease every day. In 1987 he wrote another book titled Superchops. In this second book he explained a little more detail about the direction of the movement of the lips. There is a little more analytical information for those who want it. In both of these books he writes about articulating through the teeth with the tongue touching the lips, but it isn’t until the book Trumpet Secrets (written in 2002 with Bahb Civiletti) that he insists that the tongue never breaks contact with the bottom lip. This is the biggest point that most people have a problem with when introduced to the Superchops or the Tongue Controlled Embouchure. Interestingly he actually got the idea of tonguing against the lips from ancient cornet methods such as the one written by celebrated cornet soloist Jules Levy. The idea of tonguing through the lips being bad has mainly been perpetuated by writers and teachers such as Donald Reinhardt and Claude Gordon. Throughout Jerome’s work, over the whole 30 year span outlined here, the things that didn’t evolve or change were his definitions of a correct trumpet sound.

Correct Sound:

Jerome Callet’s definition of correct trumpet sound is “Very centred and brilliant where you can hear the total resonance of the sound. Solid, but never overblown.” It is worth noting that there are certain words that are not used here, such as bright or dark. That’s because these are not accurate descriptors of sound. For further explanation of this please refer to this previous blog post.

This definition came from years of listening to the best trumpet players in the world. In order to learn what this sounds like for yourself it is recommended that you listen to recordings of Bud Herseth, Peter Masseurs, Timofei Dokshizer, Maurice Andre, Rafael Mendez, Conrad Gozzo, Charlie Shavers, Horst Fisher, Al Hirt, Roy Eldridge, or Harry James. There is no claim that these people follow the teachings of Jerome Callet, but he teaches that you should aim to sound as they do. These are just a few examples, but there is a distinct quality that these players have that others lack.

This definition of good trumpet sound is not contradictory to traditional teaching. There are a couple points that many people miss when thinking about how they sound. Firstly, the sound you hear behind the mouthpiece is nothing like what is coming out of the bell. I know this gets said a lot, but I feel that particularly in reference to a dull, spread sound it cannot be emphasised enough. Players try to spread their sound so that they can hear themselves clearly. I think it’s more important for the audience to hear me clearly. Secondly, the small rooms we practice in are nothing like the rooms in which we perform. When I began practicing Superchops I found the sound to be harsh, and the sound bouncing back off of the walls hurt my ears. When I played with that same sound in a church or concert hall the resonance was brilliant, exciting and complimented by my colleagues. My college teacher Philippe Schartz used to make it clear that piano dynamics needed to be soft, but clean enough to be heard 100 metres away at the back of an auditorium. People worry too much about sounding beautiful in a 5-metre-squared box.

Now that we’ve established the main goal of Superchops, the difference from traditional technique comes when describing how that sound is achieved.

Why Tongue on the lips?

The reason for playing with the tongue on the lips is quite simple. This way of articulating a note allows the full power of the attack to happen at the instant the sound begins. It puts everything in the right order, allowing for improved accuracy and intonation. If the tongue remains anchored to the bottom lip as instructed in Trumpet Secrets and Master Superchops (2007) then this adds stability to the embouchure. The lips grip against the tongue rather than pulling apart from each other or squeezing together, thus creating a strong structure that does not collapse into the mouthpiece.

Here is a quote from the Master Superchops DVD:

In the Arban book it says never play with a du-waaah sound. We want pomp, pomp, like hitting a bell. Never blah, blah, blah. 150 years ago, Arban described the du-wah sound as thick, disagreeable, and flat. Many modern teachers want to hear a so-called symphonic sound, not too percussive. But in starting a student or for a player who wants to correct embouchure problems, they must have a sharp attack with a tongue-stop before each note . The tongue-stop is like hitting a bell: ping-ping.

Edit (19th April 2016): Since meeting with Bahb Civiletti I have re-considered my opinion of the necessity of using the tongue to stop the air. My current thoughts are that the tongue is not making an action to stop the air; the fact that the aperture is controlled by the tongue means that the stopping of air moving is synchronised with the closing of the aperture by the tongue. It’s a chicken-and-egg situation. When playing with TCE as described by Bahb there are 5-articulations to practise that result in the same thing as thinking about the tongue-stop – the ability to maintain the tongue in the correct position.

Did you say tongue-stop? Yes. It is important here to realise that if the tip of your tongue never leaves the bottom lip then a tongue-stop does not create the unfavourable slapping sound that it would if the tongue were moving from further back in the mouth. In fact whilst you are playing this way the aperture between the top of the tongue and the cutting-edge of the top teeth is only a couple of millimetres, so stopping the sound with the tongue is quite logical. This is also the primary source of increased air compression as it acts like the valve on a bike tyre – releasing pressurised air when allowed. It is this system that makes this way of playing so efficient.

Efficiency/Correct use of air:

I’ve mentioned efficiency a few times in this post so I’ll only briefly cover the topic here. You may also wish to read my blog post Use of air: Quality not quantity for further information.

Jerome Callet writes in his books about the importance of understanding the difference between how you use air rather than how much air you have. In learning to play with compressed air and tongue on the lips you find that the quantity of air needed to play becomes less and less. At most approximately one third of that used when people talk of taking a full yoga breath. This is because the power needed to play the instrument no-longer comes from your lips resisting an air flow, but instead the air being compressed before it reaches the lips. I constantly demonstrate to pupils and other players that I can play the note ‘G’ in five different octaves without taking a breath. Sometimes I’ll breathe out first to further emphasise the point. It is not volume of air that changes the pitch of notes but the compression.

If you wish for proof of this idea then I would recommend that you search for Jim Manley on YouTube. He is not a Superchops player, but he constantly proves how he can play anything on the instrument by taking a very small breath.

Final statement:

One of the most important things to take on board when considering the teaching of Jerome Callet is that he does not claim to have any original ideas. Although his method appears on the surface to be extreme the more research I do into his ideas the more people I discover who are saying the same things. Most are not saying all of the same things, but priorities such as clean sound and efficient use of air are prevalent in the teachings and descriptions of the world’s best players. This is simply because Jerome Callet developed his ideas by observing, listening to and meeting with the world’s best players. Maurice Andre was excited by Jerome’s double pedal notes, and Pierre Thibaud wrote about them in his methods after taking lessons from Jerome (The Callet Opera mouthpiece was actually designed for Pierre Thibaud, in case you’re interested).

There is definitely more than one way to play the trumpet, and the wisest of players take tips to improve their playing from many different sources. Making a switch to Superchops or TCE is hard work and I would not recommend it for anyone who is not completely dedicated. In fact there are methods such as Jeff Smiley’s Balanced Embouchure, that are influenced by and derived from Callet’s research that people may find more favourable. Maybe in time a derivative method will gain more popularity. What would be sad is if in time the fruits of Callet’s personal success are forgotten again.

Use of air: Quality not quantity

Use of air: Quality not quantity

A discussion by Richard Colquhoun about correct breathing technique for brass players

There are a number of blog articles that I have tried to write a few times and failed to find the right approach to the topic. There are some points of view I have about trumpet playing that are not conventional and so when writing about these topics I often have to start a number of times until I feel I’ve found the right angle or voice. This is one such topic. My drafts folder has a good few attempts at this subject and this could well end up being another of those attempts. If you’re reading this then I have had some degree of success.

I usually start this topic with a story about how I started out playing the cornet in a certain way and how a journey brought me back to where I started but I’ve found that not to be helpful. Instead I’m going to make a statement and then back up that statement with the research of a respected scientist, some instrument designers and teachers. I will then throw in a simple experiment you can do that proves my point. Resistance to change is something that occurs in many disciplines and I don’t expect people’s beliefs to change overnight, but the understanding of the mechanics of brass playing has changed significantly for those who care to do the research and I hope to share that with anyone willing to listen.

“Fill the instrument” or “Use more air” are examples of the kind of uninformed phrases that one hears pouring out of the mouths of brass teachers the world over. Many of these people are suffering from an “it never did me any harm” attitude or are simply describing what they think they do rather than knowing what they actually do. Unfortunately there are also a fair number of brass method books available that describe technique based upon what people feel rather than what people do.

Here’s my statement: Contrary to popular belief, traditional teaching, and many books on the subject of brass technique the idea of using more air and developing the ability to use more air when playing a brass instrument is always wrong.

This statement is one that I first came across when I began learning about the work of Jerome Callet. On page 8 of his book Superchops (published 1987) he states:

There is a large movement to increase lung capacity and measure each player. This concept, I feel, is completely wrong. […] It is how you use your wind power, not how much air capacity you have.

But it doesn’t stop there. Knowing that there is plenty of criticism of Superchops by people who find these ideas to be too extreme to digest I decided to research further. I found out fairly quickly that Jerome was not the first or only person to be saying this. On an undated paper distributed at clinics by the Schilke Company, Renold Schilke describes an experiment whereby he demonstrates to an audience of brass instructors that it is not in fact air moving through an instrument that makes sound, but instead it is the air that is already inside the instrument that carries the sound.

If, after our lips were vibrated, the air could be disposed of in another way other than going through the instrument, the tone would be at its best. People who have used and understand physics know that this is true. However, there are people who do not understand this point. I put this as a question one time when I was giving a clinic to some bandmasters after listening to various remarks made by them about air having to go through the horn. I asked, “Is it necessary in the production of sound for the air to carry the sound through the horn?” I had hands by people in the affirmative that it was. To prove my point, I had a tuba player come up on the stage and had him blow some smoke into his tuba and begin to play. He played over a minute before some smoke finally began to tickle out the bell of the instrument. So, it is necessary to have air in the instrument so the player can establish the nodal pattern. It is not necessary for that air to move through the instrument any more than an energy impulse created by dropping a stone in water causes the water to actually move.

The paper can be found in its entirety by following this link. Here is a link to a YouTube video in which Roger Ingram, one of the worlds most accomplished lead trumpet players, describes the same idea. In his video titled Got High Notes? Lynn Nicholson also talks about how little air is needed to play, but that is a subscribe-to-view lesson so I cannot post it here.

To further illustrate this point Dr Richard Smith (12 years as chief designer for Boosey and Hawkes, and Smith Watkins Instruments for 30 years since) had an article published in the International Trumpet Guild Journal in May 1999 titled Exciting Your Instrument (available here). In that article he shows, by sealing off a mouthpiece and drilling a hole in the side for the air to escape, that the instrument works perfectly well with no air going into it at all. The article is well worth reading to open your mind to this idea.

Update: Dr Richard Smith has a video on YouTube in which he demonstrates this idea. Click here to view.

So how can we use this information to better understand brass playing and become better brass players? When asking why people believe that deeper breathing and more air is the solution we quickly find that there are a number of technical issues that are trying to be solved:

Playing a long phrase in one breath: I see this as being a matter of efficiency. You are using too much air to produce the sound and so you solve it by using more air…? By learning to play more efficiently (i.e. putting less in and getting more out) you can make your air last much longer. One way this can be done is by prioritising articulation, but that’s the subject of another blog post.

Getting out of breath whilst playing for a long time: I frequently have to remind my pupils that after playing a few long phrases the reason they feel out of breath is not because they should have breathed deeper or sooner but because they are biological creatures that need oxygen-rich air to survive. If you hold your breath for 30 seconds then this upsets your natural rhythm and you feel the need to take a few breaths to re-oxygenate your blood. I tell my pupils to breathe so that they stay alive, not because they’re playing an instrument. This idea alone can sometimes instantly solve the problem.

Misunderstanding compression: Compression of air is where all the power comes from in brass playing. To some people the only way you can get more compression is by squeezing more air into the limited confines of your body. This is the sort of approach heralded by people like Claude Gordon, Kristian Steenstrup or the guys behind Breathing Gym (a quick YouTube search will show you what you need to know about that). In learning to play with the Tongue Controlled Embouchure I have learnt that compression is created by resisting the flow of air with the tongue. The reason that it is important for it to be the tongue and not the lips is that the tongue is much stronger. It doesn’t matter how much your try to strengthen your face, your tongue will always be stronger.

Fundamentally the problem I have with a “more air” approach is that it results in a loud, spread and dull sound. Playing efficiently results in a focused, powerful and exciting tone. Loud is not the same as powerful and nor is it exciting to listen to. In the interest of keeping this post relatively concise I will recommend that you read my post titled An analysis of tone (click here).

Here’s the experiment I would like you to try: I am doing this with a normal B-flat trumpet, but any brass instrument will be fine as they all work in the same way (pitches of the notes differ). There is no preference for mouthpiece either.

  1. Remove the tuning slide and play a note on only the leadpipe. (On this length of tube you should be able to produce a pitch approximately concert E-flat above middle C)
  2. Put your hand about 1cm from the end of the pipe and feel the air moving whilst you play.
  3. The next available note in the harmonic series is approximately a major 9th higher. Play this note and observe that at the same dynamic much less air is moving through the tube.
  4. If you can produce the next harmonic (approximately a perfect fifth higher again) then you’ll notice that now there is further reduction in the air flow. You can almost block the end of the tube with your finger and still produce this note.
  5. Think about what this means.

For some people this is a good trick to learn the sensation of playing notes above the stave and to prove how easy it actually is.

A quote about tone from Trumpet Secrets

This is a quote from Trumpet Secrets Volume 1 by Jerome Callet and Bahb Civiletti. Sadly this book is now out of print but luckily I have it!

If the player tries to play with the clearest, most compact and brilliant sound, the player will produce overtones that will project the tone in the largest concert halls. Most trumpeters and trombonists are trying to develop a tone that is not truly characteristic of these instruments. The incorrect tonal abuse causes it to spread the tone too wide. When you play this way, with a “spread” tone, you cannot produce purity of sound for which your instrument was built, and you will always force your tone and over-blow.

Open your ears to the true trumpet sound.

An analysis of tone

Playing the trumpet with an appropriate tone is something that has arisen more than other topics in my trumpet-playing life. There have been a variety of reasons for this. Some of them are related directly to choices or changes in equipment and others are related to the fact that I could be playing in a salsa band one night and a chamber orchestra the next, or a brass band: all of which are thought to require vastly different tonal qualities.

When I first began playing the trumpet at the age of thirteen I had been playing a cornet for a few years already and like many young people who play both I bought a mouthpiece for the trumpet that was similar to my cornet mouthpiece. Not appreciating the difference between the two instruments at the time I had made a mistake – my trumpet now had a dull, spread tone. Years later when I was studying at music college I bought a mouthpiece with a shallower cup than my standard-issue Vincent Bach 1-1/2 C because I could play in the high register for a little longer. My teacher was not at all pleased, saying that I now had a thin/bright sound.

I do not intend this article to be about equipment and those who know me also know that I do have quite unorthodox views on equipment anyway, so I shall now steer things in a different direction. The important question to address is which words we should use to describe the tone of a brass instrument, and what those terms mean. I will also state my opinions about which are desirable qualities and give examples. I am going to present a series of terms in opposing pairs. As with colours, we cannot recognise black (no colour) without the opposing white (all of the colours combined).

Bright/Dark vs Brilliant/Dull

This is probably the easiest place to start and maybe the most loaded aspect of tone that we need to deal with. I feel that it is important and most effective to talk about the sound of a trumpet using the terms brilliant or dull rather than bright or dark because the terms brilliant/dull describe resonance whereas bright/dark actually relate more to pitch. The definition of a brilliant tone is one that is rich with high overtones and is very resonant. In a large room it would echo well as there is a lot of energy in the vibrations. In my opinion this is a desirable quality. A dull tone is one that lacks vibrancy – it is often referred to as mellow but I disagree: a flugelhorn has a mellow tone, but it must still be vibrant, not flat in sound. A dull sound is in technical terms off-centre or out of tune with the resonance of the instrument and is often the result of over-blowing – ironic really because people over-blow in order to make their sound carry.
Here are some examples:

A “dark” sound: http://youtu.be/a53s4jyCqqU?t=1m40s

This music begins with the low-pitched brass instruments. Wagner’s music is often described as needing a dark tonal quality. I think that in performing each part with the intended instrument will result in this quite sufficiently. When the trumpet has a solo at 2:21 you will notice that it does not have a dark sound at all (because that is not the trumpet’s role in the ensemble!!).

A “bright” sound: http://www.youtube.com/watch?v=mSHxFybELNY

This is a soprano cornet player called Peter Roberts who has a beautiful and vibrant tone. This, particularly when he plays softly, is the kind of sound that is often described as bright, when people just mean high in pitch. Again, I would argue that people use the word bright because he is playing a small instrument. Were he to play lower notes on a B-flat cornet then I’m sure he would not sound bright at all.

A brilliant sound: http://www.youtube.com/watch?v=TGi3Mlh4esk

Here is a clip of Sergei Nakariakov playing the Arutunian Trumpet Concerto and displaying what I would refer to a brilliant, vibrant tone.

My final argument on this topic comes in the form of logic, and a two quotes from Jerome Callet. The trumpet is the highest pitched instrument in the brass family. It is therefore not it’s job to produce a dark or dull sound. The position of the trumpet in graphic equalisation terms is to occupy the upper frequencies.

“Herbert Clarke said in 1920 that there’s no such thing as a dark sound on a soprano cornet or trumpet and if you try to make that then you’re actually gonna make things harder for yourself.”

“If you listen to a good violinist the tone is sharp and clear and brilliant; the violin doesn’t sound like a bass fiddle.”

Focused vs Spread

The definition of a focused sound is one that has a very distinct pitch. Just as with the brilliant/dull description this is a term best learned by example. You can hear in the previous clip of Sergei Nakariakov, because of the strengths of his attacks in the fast notes, that he has a very focused sound. Strong attacks are an important factor in hitting the tonal centre of a note, especially when playing fast music.
Here are some further examples of a focused sound:

Example 1: http://www.youtube.com/watch?v=0Fo4TKMknzg

This is a trumpet solo played by Wayne Bergeron, I urge you to listen to this guy as much as you can for a real experience of how every note he plays has an even tone quality right across the range of the instrument.

Example 2: http://youtu.be/Gd3DMG0lXto?t=1h32s
Here is a clip of trumpet player Jon Faddis discussing trumpet sound. If you have the time to watch this whole interview then I believe the knowledge and experience of Jon Faddis to be completely invaluable.

Example 3: http://youtu.be/7qiRWgqNhac

This is a recording of Maurice Andre. It is a perfect example of a clean, compact sound. I firmly believe that these three examples clearly demonstrate the correct trumpet sound. Coupled with a greater understanding of the terms above you can vastly improve your playing in any genre by striving to sound this way (and stop using the wrong terminology whilst you’re at it!!).

As a general rule brass players will try to spread their sound for two reasons. Firstly so that they can blend with other players – they do not realise that instruments blend as a result of good intonation and centred pitch; rather, they spread their tone in an effort not to stand out in an ensemble which ruins intonation by playing off centre. Secondly it’s a matter of power. Players do not understand that being powerful and being loud are two different things. Power comes from a compact core sound – something that is ruined by hard blowing.

Pure vs Brassy/Sizzle/Razz/Airy

The definition of a pure tone is one without any distortions and should be one of the primary goals in terms of desired sound on a trumpet. All other sounds are a direct result of deficiencies in technique or equipment. Deficiencies can also mean inefficiencies – that is wasted energy, which will result in loss of stamina, poor intonation, reduced range and often damage to the player in one form or another. I think it is important to note that learning to add to your tone for the purpose of expression is important and I wouldn’t discourage it; but these are performance techniques and should not be the only way you can play.

The thing that many people call a brassy (or even rasp-like) sound; which is much more of a feature of a trombone due to its cylindrical design; is actually a distortion caused by over-blowing. There are times when it is used to sound exciting, but quickly becomes tiresome to listen to.

My final musical example is actually of a natural trumpet played by Bahb Civiletti and demonstrates a pure tone. http://youtu.be/xyCgghWWLCw

Full/Round vs Thin

I believe the terms Full, Round and Thin all to be misnomers. They are words that are frequently used in place of more descriptive terms and it is essential to notice that they are also quite contradictory in nature.
I would define a full sound as meaning one that is both dark and rich in overtones – this is a contradiction.
I would define a round sound as being one that is brassy (over-blown), focused (distinct pitch) and broad (aka spread, i.e. not focused). That is another contradiction. Generally both full and round just mean loud. Have you ever heard of a soft yet full tone? It doesn’t make sense.
The word thin just equates to weakness. Often used to describe a tone that is high in pitch yet unsupported or airy; not a resonant tone.

Finale

I hope that you have found this article to be useful and informative. By adjusting my understanding of the role of a trumpet in an ensemble and by listening to great players, combined with the expert teachings of Jerome Callet, I have greatly improved my tone and ease of playing.

Often the greatest knowledge lies in simple logic but as musicians we are fed an awful lot of mis-information during our learning that leads to confusion that can have detrimental effects on our playing for many years. The most valuable tool you have for your development as a musician is your own ears.
