A popular pedagogist approach is to divide both men and women's voices into three registers. Men's voices are divided into "chest register", "head register", and "falsetto register" and woman's voices into "chest register", "middle register", and "head register". Such pedagogists teach that the head register is a vocal technique used in singing to describe the resonance felt in the singer's head.
Recently many vocal pedagogists have redefined the use of the terms chest voice and head voice. Vocal registration is seen today as a product of laryngeal function that is unrelated to the physiology of the chest, lungs, and head. Many vocal pedagogists argue that the vibratory sensations which are felt in these areas are resonance phenomena and should be described in terms related to vocal resonance. These vocal pedagogists prefer the terms chest voice and head voice over the term register. This view believes that the problems which people identify as register problems are really problems of resonance adjustment. This view aligns with the views of other academic fields that study vocal registration including: speech pathology, phonetics, and linguistics.
