Human Voice

Choral Music is Inherently Raceless

January 14, 2022 by Chris Munce 4 Comments

When discussing how music and education intersects with race, gender and culture, I find that we are often pretty quick to apply reductionist labels to the idea or concept. For example, phrases I have come across too often include “That’s a boy’s song,” or “Choral Music is an inherently white art form,” or “sight reading is a European value in Music Education.”

Theron Jenkins

If we label these things based on their past origins, are we sending unintentional signals to students about who is welcome NOW?

Now, it’s possible I spend too much time reading through comment threads in Facebook groups, but it raises the issue of the unintended consequences for students and educators when they see or hear such blatant essentialism, though often well intended. In the latest addition to my Choral Music: A Human Art Form thread, Theron Jenkins and I discuss this issue in hopes of bringing some alternative discourses to light for the purpose of making choral music more accessible and inviting to people from every background. After all, Choral Music does not inherently have a race, nor is group singing European. Music is INHERENTLY human. From all to all.

  • Literacy has value that transcends culture, and does not replace culture
  • Removing standards for honor choirs doesn’t help students
  • A well rounded music education can’t achieve all things for all people. Teachers must pick and choose with finite resources.
  • Representation matters!

Part 2 The human voice, an instrument in residence

January 22, 2019 by Lynn Swanson Leave a Comment


Jamea Sale, Contributing Author, DevelopingVoices.blog

Part 1 of  The human voice: an instrument in residence looked at the voice as a localized instrument in the form of the larynx and vocal folds [link to previous article]. Of course, the vocal folds do not initiate vibration of their own accord. There is energy stimulating the folds to vibrate! That energy is in the form of breath!

The Human Thoracic Cavity

The thoracic cavity can be thought of as a container holding the lungs and heart. The container is bounded by the ribs (and muscle and tissue). The ribcage, while structural, is also flexible having tissue and muscles between each rib that function to open and close the ribs. The diaphragm is situated at the floor of the thoracic cavity, and it works in unison with the ribs to draw air in and out of the lungs.

Human Lungs and Diaphragm

The diaphragm is an elastic sheath muscle the spans the bottom of the rib cage. Think of the diaphragm muscle as the “divider” of the torso. The upper torso (thoracic cavity) contains the vital organs of the heart and lungs, and the lower torso contains the viscera. The diaphragm is parachute-shaped, and it descends on inhalation and ascends on exhalation.

When the brain sends the message, “I need air!” a complex set of activity is triggered:

  1. Inhalation: The thoracic cavity must expand:
    1. The rib cage muscles are triggered open
    1. The diaphragm sheath muscle descends (contracts).

This causes a decrease in lung pressure in comparison to the atmosphere of the thoracic cavity, and air rushes into the airway.

  • Exhalation: an elastic recoil of the lung tissue occurs. The thoracic cavity relaxes.
    • The rib cage muscles close, returning to resting position.
    • The diaphragm muscle ascends.

This causes a decrease in lung volume and results in increased pressure in comparison to the thoracic atmosphere so that air rushes out of the airway.

In physics, this is directly related to Boyle’s Law. Check out this easy to understand visual explanation on Youtube:  Boyles Law from Respiratory System – Anatomy & Physiology Onlinehttps://youtu.be/q6-oyxnkZC0.

Breath trivia:

The diaphragm descends anywhere from 1.5 cm at rest to 6-10 cm during exercise.

There is no air going into the abdominals! The role of the abs is to relax and allow the thoracic cavity to be more spacious.

Breathing allows you to take in the oxygen and expel carbon-dioxide waste. But when you exhale, you also breathe out a lot of water. Humans exhale up to 0.59 fluid ounces of water per hour and about four times that amount during exercise.

The right lung is larger than the left lung in humans to accommodate the heart.

If the lungs were opened flat, they would be so big that they would cover the size of a tennis court.

The abdominal muscles required for breathing are also involved in postural support, movement, balance, coughing, urination, vomiting, singing, childbirth, and defecation.

TO DO:

I. Body Mapping the Ribs:

  • Place your hands, fingers together, on either side of your torso. Find the lower ribs. Do a long exhale. Notice the ribs drawing together toward the center of the body. As you do a long inhale, notice the rib cage “opening” and lifting. Keep your hands in the same position but move them a few inches away from your body. As you repeat the breathing exercise spread your fingers apart as you inhale and close your fingers together as you exhale.
  • Imagine you are holding a pail, one hand on the bottom of the pail and the other on the handle. Lower the handle of the pail as you exhale and inhale as you raise the handle of the pail. Now, place your hands on your low ribs. Imagine the action of the pail handle as you exhale and inhale.

II. Body Mapping the Lungs:

  • Stand with a relaxed, upright and regal stature. Allow your jaw to be relaxed and open. Exhale for a count of 4 and inhale for a count of 4. Now release to a slouched position continuing the count-breathing. As you inhale, notice how the breath intake is inhibited by this new position. Return to upright.
  • Expel all air in the lungs. Hold this position momentarily (don’t inhale). Now, release your ribs and abs and open your mouth. Simply allow air back into the lungs without “doing” an inhale. Repeat the exercise a few times. Notice that air naturally flows into the lungs due upon release of the muscles of the ribs and abs.

III. Sing!

  • Stand with a relaxed, upright and regal stature. Exhale for a count of 4. Inhale, releasing your ribs and abs. Begin an exhale and allow the voice to join the exhalation in a long sigh.
  • Repeat the previous exercise, but instead of sighing, try singing a song you like. Allow the breath to initiate the sound of your singing.

The Human Voice: An Instrument in Residence, Part 1 ~ by Jamea Sale

January 15, 2019 by Lynn Swanson Leave a Comment

The human voice: an instrument in residence

Instrument

Singers are fortunate to have a traveling instrument requiring no special assembly or installation. Even so, it is helpful to understand the make-up of the singing apparatus.

The Human Larynx

The larynx is the main structure of the human singing instrument. It is an organ suspended in the neck from the hyoid (the only bone in the larynx), and it is situated below the jaw in the neck. Its composition is primarily cartilage (seven cartilages total), tissue, membrane, and muscle.

Location of Larynx

Because the main part of the larynx is in a state of suspension, it can make excursions up and down and side to side in the neck. For singing and speaking, the laryngeal structure tilts and vibrates.

An interesting feature of the larynx is the epiglottis, which is a leaf-shaped flap of cartilage located behind the tongue at the top of the larynx. Its function is to seal the windpipe during swallowing so that food or saliva is not accidentally inhaled. Thus, the larynx is instrumental in the prevention of choking.

Parts of Larynx

Phonation

Phonation is the sound of singing and speech which occurs from the oscillation of the vocal folds and resonance of the vocal tract. Singing and speaking require a combination of changes in position, tension and mass of the vocal folds.

Vocal Folds

Vocal folds are composed of mucous membrane stretched horizontally across the top opening of the larynx. The folds are situated just below the pharyngeal tract and above where the tract splits into the trachea and the esophagus within the larynx. They are open for breathing and closed for swallowing, sealing the windpipe from food and liquid.

Superior View of Folds

Vocal folds are essential for phonation or vocalization. Phonation requires the vibrate, modulating the flow of air being expelled from the lungs during phonation.

The size of the folds affects voice pitch. Vocal folds begin growing to their full adult length and thickness during adolescence.

  • Adult male vocal folds are relatively large and thick. Male vocal folds are between 0.75″ to 1.0″ in length.
  • Female vocal folds are less dense and are between 0.5″ to 0.75″ in length.

TO DO:

 I. Body Mapping the Larynx:

  • Gently place the fingers of one hand on one side of your neck/throat and then swallow. A swallow is a complex procedure involving numerous pairs of muscles. You probably noticed the larynx moving up then back down to a neutral position under your fingers as your tongue pushed saliva to the back of your mouth and down the throat.
  • Gently place the fingers of your hand on one side of your throat and yawn. As the jaw descends and the tongue lowers for the yawn, you will notice the larynx move down.
  • Gently place the fingers of your hand on one side of your throat and carefully nudge the larynx to one side. Repeat with the opposite side. Notice that the larynx can move slightly side to side.

II. Body Mapping the Vocal Folds:

  • Gently place the fingers of your hand on one side of your throat while you hum. Notice the feeling of vibrations in your neck. Try touching around your lips, nose, jaw, skull and chest while you hum or sing throughout your vocal range. Notice the vibrations that are produced when you phonate.
Open & Close & Shortened
  • Simulate the opening and closing of your vocal folds: Beginning with your palms together as in figure ‘a,’ move your hands apart while inhaling (figure ‘b’). Now, sing a long tone as you bring your palms together. Each time you breathe, repeat the sequence, opening the palms for breath and closing for singing. Notice that the breath exhalation begins slightly before tone starts.
  • Again, beginning palms together, breathe, opening your palms as in figure ‘b.’ Bringing palms together, sing an ee [i] vowel, starting from your lowest comfortable note. Perform a glissando to your highest comfortable note. As your voice slides from low to high, move your thumbs from a forward position (figure c) to an upright position. Move the thumbs back to the starting position as you slide your low voice down to your lowest comfortable note. The thumb movement simulates the lengthening and shortening action of the folds as you sing from low to high. Be sure to open your palms each time you take a breath and close your palms as you sing.

III. Body Mapping Tension/Relaxation:

  • Gently place the fingers of your hand on one side of your throat. Open your mouth as wide as possible. Notice the tension around your mouth, neck and jaw. Now, relax the opening until it feels natural and comfortable. Practice singing a range of vowel sounds with the jaw comfortably open.
  • Gently place the fingers of your hand on one side of your throat. Make an expression of a dramatic frown and a dramatic grin. Notice the tension around your mouth, neck and jaw. Try rolling your shoulders to an extreme back position. Notice the tension around your neck. Relax to a neutral position. Experiment with a range of postures and expressions noticing any tension and exploring to find relaxation.
  • Consider how tense postures might inhibit the ability of the larynx to move, tilt and vibrate while singing.
