Why are good singing and good posture strongly interrelated? The body functions best when in an upright posture. When the skeletal structure is in proper alignment the muscles are left free to produce movement and to assist in positioning the body. Good posture allows the breathing mechanism (the actuator) to fulfill its basic function efficiently without any undue expenditure of energy. Good posture facilitates the functioning of the vibrator/resonator. It can be a psychological asset to the singer. It can help a singer secure a positive reaction from an audience. And lastly, habitual good posture can relieve much of the tension and fatigue caused by sitting or standing improperly.
What are the basic functions of the skeleton and muscles? The skeleton supports, protects, and gives shape to the body. The muscles produce movement and assist in positioning the body.
What are the adjectives that the author suggests for good posture? buoyant, expansive, erect, alert, free-to-move, vibrant, flexible, poised, tall, loose, free, happy, and balanced.
Excessive tension must be recognized and avoided.
Define tonus. Tonus is a state of slight continuous tension in muscle tissue which facilitates its response to stimulation.
What is McKinney’s description of good posture? Good posture begins with a firm foundation beginning with the feet being slightly separated and the weight of your body being equally distributed toward the balls of your feet. The feet should look natural and feel good. Legs should be free, flexible and ready to move at all times. Avoid feeling rigid or having the legs feel locked in any position. Knees should feel loose and ready to be moved at all times. Avoid locking the knees. Hips and butt should conform to the vertical line drawn from the feet to the head. Hips should be equal on both sides, and butt should be gently tucked under and forward as if you are trying to straighten the small of your back. The lower abdomen should feel that it is held in comfortably or being pulled in gently. Upper abdomen should feel free to move at all times. Think of straightening the small of your back, and creating a spinal stretch while standing as tall as you can. The chest should be comfortably high, but should remain comparatively still and quiet. The shoulders should be rolled back and then allowed to drop down until they feel as if they have settled. They should not move up or forward while singing. The arms should hang freely and naturally at your sides, with the hands following suit. The head should be in direct line with the body and balanced on the shoulders. Make sure to not jut the heat forward, or lean it backwards while singing. When sitting your body from your trunk on up should feel the same as you were standing, however your feet and legs are no longer the support -- the chair replaces their function.
What are the two types of postural faults? Alignment faults and tensional faults.
Define muscle. A tissue composed of bundles of elongated cells capable of contraction and relaxation to produce movement in an organ or part.
What is the difference between the origin and insertion of a muscle? The origin is the less movable part of the muscle. The insertion is the more movable part of the muscle. The origin name comes first, and the insertion name comes second in the name of a muscle.
In which direction do muscles pull? How many directions do muscles pull? Usually muscles only pull in one direction, therefore other muscles are required to reverse the direction of the pull.
How do we use muscles to stabilize parts of the body? Since muscles usually only pull in one direction, there are other muscles required to reverse the direction of the pull, this opposing group of muscles simultaneously stabilize some part of the body so that it can function more effectively.
What do muscles need in order to work most efficiently? They need opportunities of work and rest.
What happens when muscles are held in tension for too long? The muscle will quiver or tremble, and may begin to go into a spasm, because the contracting muscle restricts the flow of blood through it. Soreness and stiffness will follow. If held too long it will eventually lose its ability to function.
What are the two primary clues to tensional faults? 1. some form of trembling, quivering, or sharking.
2. rigidity, which may also lead to shaking.
