falsetto

Falsetto comes from Italian falsetto, a diminutive of falso, meaning 'false.' Falso derives from Latin falsus, the past participle of fallere ('to deceive, to be wrong'), the same root that gives English 'false,' 'fault,' and 'fail.' The name reflects the Renaissance understanding of the falsetto register: it was the voice a man produced by partially closing the vocal folds in a way that created a lighter, higher sound — a 'false' voice, not the full chest voice that was considered the man's natural, true voice. The falsetto was a deception of the listener's ear, or perhaps of the body's own mechanism, a way of reaching pitches that the anatomically male voice could not otherwise access. It was called little (the diminutive -etto) and false (falso) — a small deception.

The historical uses of falsetto are inseparable from the history of gender and voice in Western music. Before the development of opera and the rise of the castrato, falsetto singing by men was a standard technique in sacred choral music, allowing male choirs to sing the upper voice parts that women were excluded from in certain religious contexts. In medieval and Renaissance polyphony, countertenors — men who sang in an upper range using falsetto or a mixed technique — performed the altus (high) parts of choral works. The music of Josquin des Prez, William Byrd, and Orlando di Lasso was performed with falsetto upper voices as a matter of course. The 'false' voice was, in this context, the standard voice for an entire vocal part.

The rise of the castrato in the late sixteenth and seventeenth centuries displaced falsetto from the leading roles of opera and sacred music for roughly two centuries. Castrati — whose voices combined a child's high larynx with an adult's lung capacity — could produce a volume and brilliance that falsettists could not match. The falsetto became associated with a lighter, more intimate sound, used in secondary roles or in comic contexts. When the castrato tradition ended in the nineteenth century, operatic high voice parts were re-assigned to women or to tenor voices, and falsetto singing retreated further into folk music, vernacular song, and specialized sacred contexts such as English cathedral choirs.

The twentieth century restored falsetto to prominence through popular music. The Beach Boys' multi-part harmonies featured prominent falsetto vocals; Frankie Valli and the Four Seasons built an entire pop style around falsetto lead singing; artists from Al Green and Marvin Gaye through Jeff Buckley, Thom Yorke, and Sufjan Stevens have used falsetto as a primary expressive register. In R&B and soul, falsetto carries associations of vulnerability and emotional exposure — the voice reaching beyond its natural limit, straining toward something that the chest voice cannot reach. The 'little false voice' of the Renaissance has become, in popular music, the voice that sounds most truthful about emotional extremity.
