Vocal range is the range of pitches that a human voice can phonate. Its most common application is within the context of singing, where it is used as a defining characteristic for classifying singing voices into voice types.[1] It is also a topic of study within linguistics, phonetics, and speech-language pathology, particularly in relation to the study of tonal languages and certain types of vocal disorders, although it has little practical application in terms of speech.
Within the operatic systems of classification, there are six basic voice types. The ranges given below are approximations and are not meant to be too rigidly applied.[5]
