Flashcards in Vocabulary Homework #1 Deck (12):
A dynamic system is created when conflicting forces of various kinds interact, then resolve into some kind of partly stable/partly unstable equilibrium. The relationship between these forces and substances create a range of possible states that the system can be in. This set of possibilities is called the state space of the system. The dimensions of the state space are the variables of system.
Dynamical Systems Theory
“A system of elements that change over time.” A dynamical system theory describes the behavior of a complex dynamical system. There are many possible configurations of the system due to the large amount of options for each of the components of the system. Certain configurations will be more optimal for producing certain sounds than other configurations.
REL (Resting Expiratory Level)
The state of balance in the respiratory system before you take a breath. At this time the lung-thorax unit is in a resting position as well, and the body is not exerting any muscle effort.
This is a way to move in a more relaxed/comfortable way. The process helps to identify and lose harmful habits one has built up over a lifetime of stress. Alexander developed the technique’s principles in the 1890’s as a personal tool to alleviate breathing problems and hoarseness during public speaking.
The way in which our head, neck, and back relationship is a primary influence and dynamic organizer for the coordination of our whole body mechanism and all our movements. The primary control has also been referred to as “a master reflex in coordinating the whole psychophysical organism.”
Your brain maps structure, function, and size. Your body map commands your movement. Some people grow up with a part of their body map incorrect, they have learned something wrong, but it is possible to correct these mistakes.
The diaphragm, or thoracic diaphragm, is a sheet of internal skeletal muscle that extends across the bottom of the thoracic cavity. The diaphragm separates the thoracic cavity (which contains the heart and the lungs), from the abdominal cavity. It performs an important function in respiration. The diaphragm contracts, and then the volume of the thoracic cavity increases and then the air is drawn into the lungs.
The 22 pairs of muscles that run between the ribs and help move the chest wall when breathing. The intercostal muscles also protect the lungs. There are eleven pairs of internal intercostal muscles and eleven pairs of external intercostal muscles. During inhalation, the external intercostal muscles lift and spread the ribs, allowing for more air to be drawn in. During exhalation, the internal intercostal muscles pull the ribs closer together and force the air to exit the lungs.
The four main abdominal muscle groups that combine to completely cover the internal organs include: transverses abdominis - the deepest muscle layer. Rectus abdominis - slung between the ribs and the pubic bone at the front of the pelvis. External oblique muscles - these are on each side of the rectus abdominis.
Solfege (describe both moveable & fixed “do”)
Solege is a system for singing. It includes notes using the following names: do, re, mi, fa, sol, la, and ti.
There are two types of solfege: fixed do and moveable do.
The note names are sung regardless of key. (C, C-sharp, and C-flat are always do, no matter what).
