Voice: Technique

Singing is an integrated and coordinated act that effectively coordinates the physical processes of singing. There are four physical processes involved in producing vocal sound: respiration, phonation, resonation, and articulation. These processes occur in the following sequence:

1. Breath is taken
2. Sound is initiated in the larynx
3. The vocal resonators receive the sound and influence it
4. The articulators shape the sound into recognizable units

Some areas of vocal technique which tie to the ability to coordinate various functions are:

1. Extending the vocal range to its maximum potential: sing to the natural limits of one's vocal range without any obvious or distracting changes of quality or technique. There are three factors that significantly affect the ability to sing higher or lower:

• The energy factor — "energy" has several connotations. It refers to the total response of the body to the making of sound; to a dynamic relationship between the breathing-in muscles and the breathing-out muscles known as the breath support mechanism; to the amount of breath pressure delivered to the vocal folds and their resistance to that pressure; and to the dynamic level of the sound.
• The space factor — "space" refers to the size of the inside of the mouth and the position of the palate and larynx. Generally speaking, a singer's mouth should be opened wider the higher he or she sings. The internal space or position of the soft palate and larynx can be widened by relaxing the throat. Vocal pedagogists describe this as feeling like the "beginning of a yawn".
• The depth factor — "depth" has two connotations. It refers to the actual physical sensations of depth in the body and vocal mechanism, and to mental concepts of depth that are related to tone quality.

McKinney says, "These three factors can be expressed in three basic rules: (1) As you sing higher, you must use more energy; as you sing lower, you must use less. (2) As you sing higher, you must use more space; as you sing lower, you must use less. (3) As you sing higher, you must use more depth; as you sing lower, you must use less."

2. Posture: Good posture provides singers with a greater sense of self assurance and poise while performing. Audiences also tend to respond better to singers with good posture. Habitual good posture also ultimately improves the overall health of the body by enabling better blood circulation and preventing fatigue and stress on the body.  There are eight components of the ideal singing posture:

1. Feet slightly apart
2. Legs straight but knees unlocked
3. Hips facing straight forward
4. Spine aligned
5. Abdomen flat
6. Chest comfortably forward
7. Shoulders down and back
8. Head facing straight forward

3. Vibrato: Vibrato is used by singers in which a sustained note wavers very quickly and consistently between a higher and a lower pitch, giving the note a slight quaver. Vibrato is the pulse or wave in a sustained tone. Vibrato occurs naturally, and is the result of proper breath support and a relaxed vocal apparatus.
