VOICE MECHANISM

POSTURE
● Stand straight
● Feet slightly separated
● Knees relaxed
● Shoulders relaxed, chest opened
● Head straight (in line with the spine)
● Jaws, facial muscles and tongue relaxed


BREATH
● Breathe through the mouth and nose together
● Relax the throat and yawn
● Expand the lower stomach with intake of air
● Stomach is going out (like a balloon full of air)
● Diaphragm muscle is going down to make room for the lungs to inflate

The objective is to maintain this outward expansion even though the ribs are moving in when singing:
this is called the SUPPORT.


PHONATION
Air is going into the lungs through a channel called the TRACHEA
● There is a valve at the top of the trachea that retains the air to hold breath and to keep food from
entering the lungs. This valve consists in two muscles called the LARYNX
● Each muscle of the larynx has two FOLDS (or vocal cords): the false vocal cords and the true
vocal cords.
● In phonation only the true folds are brought together. The resistance they offer to the breath
causes them to vibrate.

THE VOWELS:
● Only the vowels are sung (consonants are noises).
● The tip of the tongue rests behind the lower teeth on all the vowel sounds.
● The tongue moves only to articulate consonants.

TONGUE VOWELS = AH => EH => AY => EE

LIPS VOWELS =AH => AW => OH => OO


RESONANCE
The resonance of the sound inside the cavities of the head: throat, sinuses,
nose, mouth brings the richness of the tone in the voice.
● Feel the resonance of your voice when you say "sing" and holding the "ng" sound.
● Hum to feel vibrations in the nose, forehead and lips. This place is called MASK
● Try to imitate the sound of a whale (mouth closed) from a high tone to a low tone; feel the
buzzing in the nasal area.


DICTION
● Consonants make speech understandable but they are an obstruction in the flow of the breath.
● The tongue must remain forward so it will not block the throat passage.
Consonants must be short and vowels connected as much as possible.


THE DIPHTHONGS
A diphthong is a combination of two vowel sounds back to back.
For singing, the vowel sounds are slightly modified from those used in speech.
● "My" would sound like M-ah (as in far) – ee (as in see)
● "Day"D-eh (as in end) – ee (as in see)
● "Now" N-aa (as in at) – oo (as in soon)
● "You" ee (as in see) – oo (as in soon)
