falsetto (fôlsĕtˈtō) [key] [Ital., = diminutive of false ], high-pitched, unnatural tones above the normal register of the male voice, produced, according to some theories, by the vibration of only the edges of the larynx. Some male altos are tenors skilled in the use of falsetto. Falsetto tone is usually thin and expressionless, but can be used with good effect.
