Developing your best voice range as singers
Understand the physiological aspects of voice
When we hearing production, there are including the functions of the larynx, vocal cords, and resonant cavities. Larynx, hollow chamber in which the voice is produced; In mammals and amphibians it is located in the front or upper part of the trachea. In mammals it joins the lower portion of the pharynx with the trachea and occupies a frontal or ventral position in relation to the esophagus, behind the skin and connective tissue of the throat. The larynx is attached by ligaments to the hyoid bone, located at the base of the tongue.
The skeletal frame of the larynx is a set of three large cartilaginous structures—epiglottis, thyroid cartilage, and cricoid cartilage—and several pairs of small cartilages, the most important of which are the so-called arytenoids. The epiglottis is a wide cartilage located in front of the thyroid that extends to the top of it. It swings over the opening of the pharynx towards the interior of the larynx; During swallowing, the larynx rises and compresses the epiglottis and the root of the tongue, thus preventing food from entering the airways.
Just below the epiglottis is the angular thyroid cartilage, made up of two vertical plates that meet at the front of the neck. The union of these plates forms the projection called Adam's apple or bite (the name comes from the Genesis story, according to which when Adam ate the apple, a piece got stuck in his throat). The posterior portions of the thyroid cartilage embrace the circular cricoid cartilage, which keeps the larynx always open. On each side of the superior posterior border of the cricoid is a small mobile arytenoid cartilage.
The human larynx has two pairs of vocal cords made up of elastic connective tissue covered by folds of mucous membrane. One pair, the false vocal folds, extends from the epiglottis to the angle of the thyroid cartilage; These cords narrow the glottis (the pharyngeal opening of the larynx) during swallowing. Below them are the true vocal cords, which extend from the arytenoid cartilages to the angle of the thyroid. The vibration that the air from the lungs causes in this pair of strings determines the formation of sounds that amplify the resonant nature of the larynx.
