Falsetto

Falsetto ( fawl-SET-oh, fol-, Italian: [falˈsetto]; Italian diminutive of falso, "false") is the vocal register occupying the frequency range just above the modal voice register and overlapping with it by approximately one octave. It is produced by the vibration of the ligamentous edges of the vocal cords, in whole or in part. Commonly cited in the context of singing, falsetto, a characteristic of phonation by both male and female sexes, is also one of four main spoken vocal registers recognized by speech pathology. The term falsetto is most often used in the context of singing to refer to a type of vocal phonation that enables the singer to sing notes beyond the vocal range of the normal, or modal, voice (M1).
