Messa di voce

Messa di voce is a vocal technique in which a singer gradually increases and then decreases the loudness of a sustained note while keeping its pitch steady.

Vocal fold: A pair of tissue folds in the larynx that vibrate to produce voiced sound. Their vibration must remain stable as the singer increases and reduces vocal intensity.
Bel canto: A style of Italian vocal music prized for smooth tone, agility, and expressive phrasing. Messa di voce became a hallmark exercise and expressive device in bel canto singing.
Vocal pedagogy: The teaching and study of vocal technique and singing. Teachers use messa di voce to develop control of breath, tone, and dynamics.
Vibrato: A small, regular variation in pitch, loudness, or both during a sustained musical tone. Vibrato introduces periodic fluctuation, whereas messa di voce shapes loudness across a single arc.
Subglottal pressure: Air pressure below the vocal folds, generated by the respiratory system. Its controlled increase and decrease help shape the note’s swell and fade.
Italian opera: Opera composed and performed in the Italian-language tradition. The technique developed within a tradition that made sustained vocal expressivity prominent.
Crescendo: A gradual increase in musical loudness. The first half of messa di voce forms a crescendo on one sustained pitch.
Portamento: A vocal or instrumental glide from one pitch to another. Portamento changes pitch between notes; messa di voce keeps the sustained pitch steady.
Phonation: The production of voiced sound through vibration of the vocal folds. Messa di voce is a controlled dynamic change within sustained phonation.
Giovanni Battista Mancini: An eighteenth-century Italian singer and singing teacher known for his treatise on vocal training. His writings describe the technique as a demanding exercise in breath and tonal control.
