Singing Anatomy

Abdominal Muscles: 
A large muscle in the front of the abdomen that assists in the regular breathing movement and supports the muscles of the spine while lifting and keeping abdominal organs such as the intestines in place.

Abdominal Muscles

 

Arytenoids:
Pertaining to either of two small cartilages at the back of the larynx. They allow the vocal folds to be tensed, relaxed, or approximated (brought together).

Arytenoid Cartilage

 

Diaphragm:
The diaphragm is a large curved muscle that serves as a demarcation between the chest and the abdomen. This muscle lifts the lungs when you exhale, pressing air out of your chest, and contracts downward to open up your lungs, mouth and nose when you inhale. This is the prime muscle that helps the body create the suction necessary to breathe in. ALSO Diaphragm: “The dome shaped muscle attached to the bottom of the lungs that separates your chest and stomach cavities. Its main function is to initiate inhalation.

Lungs


Epiglottis:


The erect cartilage at the root of the tongue which covers over the ’Glottis’ whilst swallowing in order to prevent food from entering the trachea.

Glottis:
The ‘Glottis’ is an opening situated at the upper part of the windpipe/trachea and between the vocal chords. It affects the modulation of the voice by contracting or dilating.
Glottis: The airspace between the vocal folds.

Hard Palate:
The hard palate is a thin horizontal bony plate of the skull, located in the roof of the mouth. It spans the arch formed by the upper teeth and forms the partition between the mouth and nasal passages. It is an important area of resonance for the voice and is also essential in the production and pronunciation of consonants such as ‘d’ and ‘t’. Also a resonator…

Inter Costal Muscles:
External: The external Inter costal muscles are responsible for expanding the rib cage during inhalation. These are the muscles we use to hold the rib-cage ‘up’ whilst singing.
Internal: The internal Inter costal muscles are responsible for the contraction of the rib-cage, bringing it back down into a ‘resting’ position. It is the acting of the internal Intercoms that we singers try to resist in order to maintain breath control without allowing the rib-cage to drop back down too quickly.

Larynx:
AKA the ‘voice box’. The larynx houses the vocal folds and can be felt at the front of the neck. Try placing your fingers at the front of your neck – about mid-way between your bottom jaw and the place where your collar-bone meets in the middle. Swallow – you will feel the larynx move up and then back down again to a ‘resting’ position. Also a resonator…

Lungs:
Well, it’s a formality really, that the Lungs appear in the anatomy section. We’re all aware of their function, however, it’s important to understand that we do not always use our full lung capacity when we sing. This is because we are often so used to only using the upper section of the chest and lungs. To be able to support the voice and learn better breath control whilst singing, we need to focus the breath lower into the ‘bottom’ section of our lungs so that the diaphragm is properly and fully engaged, the lower rib-cage is expanded further and the oblique’s and abdominal muscles can be use more effectively.
Lungs

 

Oblique Muscles:
Found on the sides of your body and extend down in a ‘V’ towards the groin area (*External* Oblique’s described VERY generally). Keeping the oblique muscles contracted during exhalation (singing) helps to keep the diaphragm from relaxing back to it’s neutral, higher position, as is found after full exhalation occurs.
Oblique Muscles

 

Pharynx:
The ‘canal’, that connects the mouth and nasal passages with the larynx …Often simply called ‘The Throat’. Also a resonator…
Pharynx

 

Resonators:
Pictured here, some of the resonating cavities by which the sound is amplified. These are the areas to which, (after initial phonation) the sound wave travels to, and causing intense vibration, produces the ‘phenomenon’ we call SOUND! The main resonating cavities in the body are: Chest, Trachea,Larynx, Pharynx, Mouth, Nasal and Sinus cavities.
Resonators

 

Soft Palate:
The soft palate is movable, consisting of muscle fibers sheathed in mucous membrane. It is responsible for closing off the nasal passages during swallowing, and also for closing off the airway. In Singing, ‘lifting the soft palate’ can enable us to maximize our vocal strength and beauty of tone.

Trachea:
AKA the windpipe – serving as the main passageway of air to and from the lungs. Also a resonator…
Trachea

Vocal Chord Positioning:

 Vocal Chord Positioning

In your lower or chest register, your vocal cords are vibrating along the full length of the cord, thus producing a slower  vibration and lower pitch. (See Above) In your middle or mix register, they are for example, zipped up to about half their length – thus causing the vibration of the cords to become faster – thus producing a slightly higher pitch. (See Above) In your upper register or head register, the vocal cords are zipped up to about 2/3’s of their length, thus producing and even faster vibration resulting in an even higher pitch. (See Above)

Vocal Folds:

Also called “vocal cords.” Two ‘folds’ of mucous-secreting membrane stretched horizontally across the larynx which initiate ‘phonation’.
The folds, ideally, should open during inhalation but gently and fully close just prior to phonation. The closing of the vocal folds creates a degree of resistance to the air that is coming up from the lungs, and they begin to buzz in response to the pressure building up beneath them. This buzzing is the basic sound of the voice, before it is shaped by the vocal tract and resonators, into specific sounds/tones.

 Uvula:

A small mass of fleshy tissue that hangs from the middle of the soft palate.

    now that I am taking what started as a bit of casual fun more seriously, it is a revelation to begin to understand  a little of what is involved in singing!!! I need to grasp this and be able to pass it on to my newly formed choir!
    Thanks!

    Amazing!!

    Awesome Marion! Say “Hi” to your choir members for me! Rae xx

Client Success Stories

"You are such a darling person, aside from your tremendous talent. Your love of life, for your students, and your joy pervade all your instruction, along with your beauty and your delightful humor. Here I was in Florida watching and learning live from Austrailia. I am a grandmother who started piano lessons some years ago, and have had a few vocal lessons. I had the life-long habit of speaking in a husky voice, speaking on my vocal cords, and my teacher helped me to learn to speak in the "front" of my mouth. I was a tough case and I find I need to keep at it! I am very busy, but am working to find a routine of implementing your vast resources. It is wonderful to have it available with such detailed help 24/7. I especially liked your tender care and constructive assistance to each one who sent in videos, again with concrete teaching, flashed with humor and genuine love. You can't fake that. You taught me much by your patient composure while (whilst!) waiting for your husband to get the little one in the tutu. You had just been teaching about not grimacing and it was then shown to us how NOT to do it! It was a great lesson to watch and HEAR you perform the three lovely pieces with such focus and to see how you moved from one to the other, with the right timing and redirection in between. (does that make sense?) Anyway, you have a lovely voice and an especially wonderful, natural way of teaching by demonstration as well as by explanation."
