{{Vocal registration}}

''Vocal registration'' refers to the system of vocal registers within the voice. A register in the voice is a particular series of tones, produced in the same vibratory pattern of the [[vocal fold]]s, and possessing the same quality. Registers originate in [[larynx|laryngeal]] function. They occur because the vocal folds are capable of producing several different vibratory patterns.<ref>{{Cite journal|title = Chest- and falsetto-like oscillations in a two-mass model of the vocal folds|journal = The Journal of the Acoustical Society of America|date = 1996|issn = 0001-4966|pages = 3355–3359|volume = 100|issue = 5|doi = 10.1121/1.416976|first = Jorge C.|last = Lucero|bibcode = 1996ASAJ..100.3355L}}</ref> Each of these vibratory patterns appears within a particular range of [[Pitch (music)|pitches]] and produces certain characteristic sounds.<ref name="Large">{{Cite journal

* A particular part of the [[vocal range]] such as the upper, middle, or lower registers.
* A [[resonance]] area such as [[chest voice]] or [[head voice]].
* A [[phonation|phonatory]] process (phonation is the process of producing vocal sound by the vibration of the vocal folds that is in turn modified by the resonance of the vocal tract)
* A certain vocal [[timbre]] or vocal "color"
* A region of the voice which is defined or delimited by vocal breaks.

In [[linguistics]], a '''register language''' is a language which combines [[tone (linguistics)|tone]] and vowel [[phonation]] into a single [[phonology|phonological]] system. Within [[speech pathology]], the term vocal register has three constituent elements: a certain vibratory pattern of the vocal folds, a certain series of pitches, and a certain type of sound. Speech pathologists identify four vocal registers based on the physiology of laryngeal function: the [[vocal fry register]], the [[modal register]], the [[falsetto register]], and the [[whistle register]]. This view is also adopted by many vocal pedagogues.<ref name="McKinney 1994" />
