<sod> '''Creaky voice''' (also called '''laryngealisation''' or, in [[singing]], '''vocal fry''' or '''glottal fry'''), is a special kind of [[phonation]] in which the [[arytenoid cartilage]]s in the [[larynx]] are drawn together; as a result, the [[vocal folds]] are compressed rather tightly, becoming relatively slack and compact, and forming a large, irregularly vibrating mass. The frequency of the vibration is very low (20&ndash;50 pulses per second, about two octaves below normal voice) and the airflow through the [[glottis]] is very slow. A slight degree of laryngealisation, occurring e.g. in some [[Korean language|Korean]] consonants is called "[[stiff voice]]".
 
 There is some argument among music instructors as to whether or not this is an actual register as it can be used to add a raspy sound to other registers. By putting less amount of air on the cords than is needed for a clear tone of the pitch you are going for, the tone breaks up and becomes a rasp. Many [[Nu metal|Nu Metal]] singers use this technique to create a screaming sound. One example is [[Chester Bennington]] of [[Linkin Park]]. [[Yeah Yeah Yeahs]]' singer [[Karen O]] also utilizes the technique in songs like "Rich" and "Art Star".
