A book of lip building and
I
flexibility exercises by JnhnRidneon
FOREWORD
I have attempted to write a collection of supplementary exercises concentrating on the generally
overlooked area of study — lip building and lip flexibility.
It includes advice on the essential physical aspects of brass technique, relating specifically to breathing,
resistance and the formation of the embouchure.
For the beginner there is positive instruction on establishing a good approach, for the player in
difficulties a basis for rehabilitation is provided and for those with a sound embouchure I have
included many lip building exercises to develop range, stamina and lip ‘teasers’ to develop flexibility.
This collection is not a magic formula guaranteed to transform an embouchure overnight, but rather
a concise assemblage of my observations and exercises arrived at and written during years of intensive
teaching and research.
If, having read the text, you recognize an apparent embouchure fault do not attempt to rectify it
at once. This invariably prevents a player from performing for some time, leading to frustration
and anxiety, symptoms more detrimental than the original physical defect. Changes should be made
gradually, working towards the ideal over a period of months. In fact ‘make haste slowly’ is the best
advice one can proffer generally, but particularly in relation to lip building exercises when developing
range. High notes, if they are to be produced correctly, are dependant on gradual muscular de-
velopment.
Towards the end of the book 1 have incorporated studies requiring lip flexibility, fingering dexterity
and a facile tonque action. They are demanding but the additional range, flexibility, stamina and
confidence gained through successful application of these exercises more than compensate for the
hours of labour.

HOW BRASS PLAYERS DO IT

BREATHING WELL?
The trouble with most people’s breathing is that just How do these muscles bring about the change in the air

increasing the depth of the cavity. The rib muscles add to
this expansion by increasing the distance between the ribs
and lifting the whole rib cage. These two methods of
breathing are not entirely separate and are used in com-
bination, but it is desirable for the brass player to be able
to isolate these contractions at will.

Let us talk about the correct method of inhaling. Air is
drawn in through the mouth by inducing a change of Umbilicus
pressure which activates a movement of air into the lungs.
There are two main ways of achieving this:
1. The contraction of the principal breathing muscle,
the diaphragm, which is situated below the lungs.
It separates the chest from the abdomen.
When the chest cavity is increased in this way, the air

exhalation in order to produce different dynamic levels and
a multitude of vibrations. Consequently he must use
additional muscular contractions to support the normal
breathing-out process. The muscle concerned was not, of
course, included in the human body for the purpose of
playing a brass instrument, and is regularly employed in
other occupations such as coughing. In each case its use
provides an additional supply of air. In coughing, the
articulation takes place in the throat. In brass playing it is
normally governed by the tongue. Otherwise the action
and the effect are identical.
This extra support comes from the transversus abdominus,
which is in the abdomen and attached to the diaphragm.
Referring again to the beach ball, the effect of this muscle
is like that of grasping the ball and giving it a healthy

squeeze. I have already said that the abdominal muscle is
used for coughing. Let us now find other ways of bringing
it into use, thus discovering an awareness and ultimately
control over this mysterious ‘pump house’.
Suspend a large sheet of paper at arms length between
thumb and finger. Now blow, so that it does not flap but
is held at a steady angle. Having achieved this, increase the
abdominal effort,and in so doing blow the suspended sheet
even farther away from its original position. You will
become acutely aware of the need for increased support in
order to maintain constant air pressure. This can be directly
related to the production of a sustained note free from
‘wobble’ or ‘fade out’.

to synchronise the two methods, starting with the dia-
phragm and moving smoothly into costal breathing.

RESISTANCE
Inhalation and exhalation are the primary factors of brass
tone production. Having mastered these, the next logical
step is control of the breath required, firstly to support
life and secondly to achieve a regular lip vibration. Surplus
breath is as wrong as inadequate breath. Insufficient air
creates physical discomfort and lack of support for an
extended phrase while an abundance of oxygen causes an
explosive sensation in the chest, throat and head cavities,
resulting in the inability to achieve satisfactory control for
anything other than a loud passage. A smaller volume of air
is required for short, soft notes in the high register than for
long, loud notes in the low register, so take the trouble to
look carefully at the music you are about to perform and
decide in advance how much breath is required for each
phrase. You will be rewarded by feeling more comfortable

and relaxed.
Glottis Opened
(Loud note)
Having observed the degree of breath needed for each
phrase, be conscious of the correct method of controlling
the air flow in note production. When the air is projected
forcibly by the supporting abdominal muscles, and is at no
point resisted, the duration of the exhalation will be very
short. If you are one of those players believing that any
opposition to the air flow restricts tonal quality and
should therefore be avoided, try the following experiment.
Take your largest breath, holding the throat wide open,
and produce a HAA breathily and without exercising the
vocal 'chords. Now do you believe that resistance is
necessary! Repeat the same thing, but this time say HAA
vocally. This automatically reduces the size of the glottis
and creates resistance. Even with increased abdominal
support the breath lasts much longer. This high-lights the
significance of resistance and leads us to ask the question,
‘at which points in the breath’s journey do we introduce

Tongue
An observer casting a cursory glance at this problem might
be forgiven for assuming that if considerable air pressure,
created by the contraction of the abdominal muscles in
support of the diaphragm and intercostal muscles, is
required for loud notes then the reverse must be true for
quiet notes. In reality nothing could be further from the
truth. When we breathe out, under normal conditions, the
diaphragm and the intercostal muscles return to their resting
position passively, without muscular contraction. This is
Mr. Average’s mistake. He relies upon the elasticity of the
diaphragm and the intercostal muscles to expel air in a
gentle manner so establishing a ‘piano’. This is simply not
on! Firstly, he creates a flimsy sound lacking in security.
Secondly, he does nothing to provide the machinery for
adjusting the air supply to the note (this point will be

the fall — follows a deliberate path to the ground. The same
principle applies in producing a controlled soft passage.
How then do we achieve this control free from the many
hazards that lend themselves so naturally to colourful
adjectives? The simple reply is to utilize the abdominal
muscles in the same fashion as for loud passages but with
less contraction. You may say, this is all very well but

The aperture
The final adjustable resister to the air flow is created
between the red membrane of the lips. Some authorities
state that the aperture is fully occupied in merely selecting
notes, but in my opinion the only possible way a brass
player can achieve a vibration is by causing resistance to the
air stream at the aperture, thereby exciting the red tissue
and the attacking air column to oscillate. One only needs
to consider the effect a crescendo has on intonation — when

stantiate my own view that the aperture is essentially
a resistor. The average player’s teeth overlap at the top and it is
necessary to realign them by thrusting the jaw forward.

sensitive control necessary to gain complete mastery over
all these minute movements, demands understanding or an
abundance of natural aptitude. Even if you are fortunate
enough to be well endowed with talent and have a natural
physical approach to the instrument, as some undeniably
do, it is as well to pursue an understanding of the subject,
for many a ‘born player’ has woken one morning to find
that things were not quite right. What then?
THE EMBOUCHURE
The function of the brass player’s embouchure is to convert
a flow of air into varying vibrations. Before considering the
facial muscles involved and the skills necessary to control
them, we must determine the structure on which the
embouchure is founded. This is fundamental, as any
maladjustment of the jaw and teeth creates production
problems. It is of prime importance to establish the correct Muscles employed in forming the embouchure
relationship between the jaw and the upper teeth before
proceeding.
Muscles A-E, when contracted, pull the flesh of the cheeks
upward and outwards away from the lips. F-I pull the flesh
away from the lips but downwards. Each of these muscles
is powerful from frequent exercise, whilst the lip muscle K
is far less developed. Unfortunately this has to support the
full weight of the mouthpiece, instrument, and pressure
generated by arm weight. When the lip muscle contracts it
gathers the flesh into a pucker, pulling against the opposing
action of the cheek and chin muscles. This results in the lips
being held in a state of tension responsive to the slightest
manipulation, but with the balance of power heavily
weighted in favour of the outward contraction.
The modiolus muscles J, placed either side of the mouth,
mediate in this struggle, generally supporting the action of
the lip muscle. Their anchored position influences the

When acquainted with the muscles it is necessary to exper-
ience how they function. Place your fingers on your cheeks
while flexing the eye muscles. You will witness the con-
siderable lifting capacity of these and the nose muscles if
you repeat the exercise with the fingers on either side of
the nose. Next, place your fingers either side of the mouth
while grinning broadly. Each contraction pulls the flesh
away from the aperture.
You will find it very difficult to isolate the contractions of
the individual chin muscles, and as this serves no useful
purpose it is more valuable to develop an awareness of their
combined effort. Close your front teeth, without over-
lapping, and pinch the lips. Now move the flesh of the chin

In establishing the aperture it is important to appreciate
that the dimensions will vary from person to person and
from instrument to instrument. It is better not to ponti-
ficate on this subject but to leave it to the individual to
experiment. You should however know that too large an
aperture makes for a breathy, dull quality of sound, while
the opposite extreme produces a harsh, brittle tone.
If you have established the correct structural and muscular
conditions you need only separate the teeth to make an
aperture. (Figure 14) This will be too wide, and it will be
necessary to nip the red membrane on either side, narrow-
