The singing technique is divided into four main subjects. By combining elements of these four subjects, we can design our own sound, as well as finding concrete solutions to specific problems.

1. The three overall principles are the fundamentals of healthy vocal production in speaking and singing, regardless of the musical style.

Support:

Controlling the air flow and air pressure, to achieve a stable and accurate tone. This is done by working with different muscle groups for a stable movement of the diaphragm.

Necessary Twang:

Maintaining the necessary acoustic shape in the epiglottic funnel, above the vocal folds.

Avoiding protruding the jaw and tightening the lips (avoiding excess jaw and lip tension), as it often produces uncontrolled constriction around the vocal folds.​

2. The Four Vocal Modes:​

All voices can produce the four vocal modes in speaking and in singing. These are four different settings in the vocal tract that has different shapes, different sounds, and different guidelines. They are: Neutral, Curbing, Overdrive and Edge.​

3. Sound Color:​

All modes can be lightened or darkened, though some more than others. The sound color is created in the vocal tract, which is the space above the vocal folds extending to the lips and including the nasal passages.

4. Effects:​

Effects are sounds that are not connected to melody or text but are sounds that underline the expression or style of a singer. All effects are produced in the vocal tract and include vibrato, distortion, growl, grunt, rattle, ornamentations, breathiness, and creaking.
