Chapter Summary: To sing freely one must be able to breathe freely. To breathe freely one must have good body alignment. We must learn how to be aware of our posture. A proprioceptor is a sensory receptor in the body that gives us a sense of self. We can use this to access our posture and breath. In the posture exercises I enjoyed the tip to stand on the balls of your feet. It made me feel more ready to "take off" and made my posture feel upright, yet comfortable. The diaphragm is not only a muscle for breath, but also for posture. Without proper body alignment the diaphragm is unable to move passively. When the diaphragm is lowered with the intake of air, it tends to exert a lateral pressure to help expand the ribs. It also helps to open the glottis, and lower the larynx (due to it's connection to both the pericardium sack, and the larynx).
The rib cage is expanded by the external intercostals and contracted by the internal intercostals.
Breathing through the nose is nature's own system of filtering, heating, and humidifying.
Through the Venturi effect, phonation occurs due to the vehicle of breath. "The beautiful voice is the result not of exertion of great power but rather of delicate control."
Key Terms: posture, breathing, proprioception, kinesthesia, tidal volume, complemental volume, supplemental volume, residual volume
Key Concepts: Good body alignment is essential to breathing and singing freely. Imagine breath like the swing of a pendulum. Breathing through the nose is nature's system of filtering air.
Making Connections: The breathing through the nose part in the chapter struck me as a very interesting concept. I want to try doing that as I walk to school during the winter months to see if it helps with my asthma.
