Why are good singing and good posture strongly interrelated?

-The body functions best when the skeleton supports the body with the muscles. The voice functions best when air can move freely. The vibrator and resonators function best when they are free from tension. The singer functions best when he has an established comfortable singing posture . The audience functions best when they have a sense of confidence in the singer. The overall health of the singer benefits with good posture by becoming more efficient.

What are the basic functions of the skeleton and muscles?

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? 

-Origin is less movable than the insertion.

In which direction do muscles pull? How many directions do muscles pull? 

-The direction of the pull is to the origin. Muscles only pull in one direction, so pairs of muscles are required for full range of motion.

How do we use muscles to stabilize parts of the body? 

-By simultaneously bringing opposing groups of muscles into use.

What do muscles need in order to work most efficiently? 

-Muscles need opportunities to relax in order to be efficient

What happens when muscles are held in tension for too long?

- Begin to protest in various ways such as: quivering or trembling; if muscles still are not released they will begin to shake more violently in what is known as a tetanic flutter; intense pains may develop; soreness and stiffness; and if the tension is still not released, the muscle will lose its ability to function.

What are the two primary clues to tensional faults?

- 1-some form of quivering, trembling, or shaking, and 2-rigidity
