messa di voce
A vocal technique of gradually swelling and diminishing volume on a single held note.
In Depth
Messa di voce is a vocal technique where the singer begins a long note softly, gradually swells to full volume, then diminishes back to soft — all on a single pitch. The Italian term means placing of the voice and represents one of the most demanding tests of vocal control.
This technique was considered the supreme test of bel canto singing in the 18th and 19th centuries. It requires perfect breath support, consistent vibrato, and seamless dynamic control across the full range of volume. Wind instrument players also practice messa di voce as a fundamental exercise in tone production and breath management.
In the 18th century, a singer's career could be made or broken by the quality of their messa di voce. Audiences would attend specifically to hear how a star handled this single sustained effect.
