Warming The Voice
While singing may seem heavenly, vocal production itself is a down to earth physical experience,
requiring athletic discipline as well as artistry. As any athlete knows, an effective warm up is
essential
for optimal performance.
Why should singers warm up? No one would expect a gymnast to stand up and perform
back-flips after a full meal, but singers who are dinner guests are frequently asked to perform
"on-the-spot entertainment," after dessert and coffee. The wise singer will politely decline, rather
than
reveal his raw vocal product, which is further hindered by a bloated stomach! Warming up allows the
singer to "get-in-touch" with herself or himself, both physically and psychologically, and to
experience
that kinesthetic self-awareness which is the foundation of a secure vocal technique.
Allowing time to warm up
Ideally, the warm-up procedure should be unhurried a leisurely
self-exploration that allows adequate time for gradual loosening and coordination of countless
muscles, large and small, which contribute to vocal production. Warming up should be an enjoyable
experience, comparable to a luxurious massage. All too often, unfortunately, the singer is warming
up
while rushing to a rehearsal, or frantically trying to learn his music at the last minute. The pressure
of
"too little time" results in physical as well as mental tension, and warming-up is difficult, usually
ineffective, or even counter-productive.

The warm up procedure
Singers develop distinctive warm up regimens appropriate to their
personal needs; these may vary considerably with changes in physical, mental, and emotional well
being. Nevertheless, consistency in the overall approach is most beneficial. Many singers begin by
warming-up the entire body with gentle physical exercise (e.g., stretching, yoga, Tai Chi). This helps
to alleviate the muscular tension that interferes with vocal production, as well as to stimulate the
deep
breathing which is necessary for good support of the voice. The muscles of articulation, which
include
the jaw, tongue, lips, and soft palate can be loosened with appropriate exercises, which also can
help
to activate the singer's expiratory airflow. Before beginning to explore the day's potential for vocal
resonance, the singer should be relaxed, yet vital. If the singer is fatigued, or not feeling well, it will
be
necessary to "energize" himself, so that he can provide adequate breath support for singing. It is
wise
to begin vocalizing in the most comfortable mid range of the voice, and gradually work out to the
higher and lower extremes of pitch. High notes (faster vocal cord vibration) may require substantial
airflow. and increased pharyngeal space. Low notes, which use a "heavier" mode of vocal cord
vibration (thicker vibrating mass), also require appropriate support. Recent biomechanical studies at
The Center for Voice Disorders have shown that singing at the extremes of pitch both the
highest and lowest notes of the vocal range can strain the laryngeal muscles, and can result in
undesirable (and potentially harmful) patterns of muscle tension. Therefore, it is good common sense
to avoid the "outer extremes" of the voice until one is well warmed up. In the mid range, the singer
may safely begin the daily search adjustments in the size and shape of the pharynx. Considering
the
countless possible configurations of the vocal tract, the process of developing a resonant tone is an
ongoing one, even for seasoned professionals. Most of a singer's warm up is devoted to the
objective of obtaining a beautiful vocal timbre through the use of an enormous variety of vocal
calisthenics.
Finally, the singer is likely to test his vocal register transitions during the warm up. Exercises that
"blend" the "chest" ("heavy" laryngeal adjustment) and "head" ("light" laryngeal adjustment) registers
eventually produce a smooth passaggio, resulting in an "even scale" from the "bottom" to the "top" of
the vocal range.

Warming down
The long-distance runner will spend a good amount of time stretching and massaging muscles after
a marathon, and likewise, the singer who has extended himself should "warm-down" his voice, with
exercises that "soothe" the vocal cords (vocalizing on "oo," for example). If the singer has been
using a "belting" voice, it is especially helpful to sing in the "head" register (or falsetto), which
stretches the vocal cords and alleviates laryngeal tension caused by the "heavy adjustment," or
thick vibrating mass. Re-loosening the articulatory muscles, even without phonation, is therapeutic.
Massaging the jaw the masseter ("chewing") muscles as well as other muscles of the neck and
shoulders, particularly the trapezius (which arise from the back of the head and vertebrae in the neck
and chest, and extend to the collarbones and shoulder blades) provides welcome relief to the singer.
