Singing involves a voice system broken down into three different parts of the body. Each subsystem has a specific role when you are singing. Each part plays a specific role to produce your vocal sound.

The first subsystem is the “air pressure system” which consists of the diaphragm, ribs, chest muscles, abdominal muscles and lungs. The air pressure system provides and regulates air pressure to cause vocal folds to vibrate (See blog 2/1/21, “How To Have Strong Breath Support When Singing”). The air pressure system is your air supply. Think of the tires on a bicycle or a car; if the air pressure is too low or too much air, the bicycle or car will not as good as it should (see blog 9/12/20, “How Singing Works – Breath Support”). The amount of air flow and pressure passing through the larynx will determine the strength and loudness of your voice.

The second subsystem is the “vibratory system” which includes the voice box (larynx) and vocal folds (cords). The air pressure is converted into vibration. When the vocal folds vibrate, they change the air pressure into sound waves (vibrations) which produce a buzzing sound (See blog 11/4/20, “Unlock The Key To Your Voice - The Larynx”). The larynx is also part of the vocal tract, but we are separating it because the vocal folds create the vibration.

The third subsystem is the “resonating system,” which is the vocal tract: throat (pharynx), oral cavity and nasal cavity. The resonating system changes the “buzzy sound” into your singing voice (See blog 12/14/20, “Your Own Personal Acoustic Chambers”). The air passing through the vocal tract and air pressure causing the vibration shape your tone through resonance. Resonance is the intensity and quality of tone you hear when you sing. The throat, oral cavity and nasal cavity create a deeper, fuller, reverberating sound in your voice.
