Voice classification in non-classical music
There is no authoritative system of voice classification in non-classical music[1] as classical terms are used to describe not merely various vocal ranges, but specific vocal timbres unique to each range. These timbres are produced by classical training techniques with which most popular singers are not intimately familiar, and which even those that are do not universally employ them.[2]
The ranges given below are approximations and are not meant to be too rigidly applied.[1]
Some men, in falsetto voice or as a result of certain rare physiological conditions, can sing in the same range as women. These do not fall into the female categories, instead called countertenors within classical music. Within contemporary music, however, the use of the term tenor for these male voices would be more appropriate[8]
Vocal pedagogical methods for contemporary commercial music[edit]
Teaching voice within non-classical music is an emerging field. Up to this point, voice teachers and voice research have been largely concentrated with classical methods of singing. However, new approaches and methods to teaching non-classical voice have recently emerged, such as the complete vocal technique (CVT)[10] by Cathrine Sadolin at Complete Vocal Institute or speech level singing (SLS)[11] by Seth Riggs. Another example is Jeannette LoVetri's method known as somatic voicework.[12] It has really only been within the last few years that music conservatories and music programs within universities have begun to embrace these alternative methodologies suitable to other kinds of vocal music.
