Vibrato

Definition

Vibrato is a musical technique involving a slight, rapid variation in pitch that adds warmth and expressiveness to the singing voice. This oscillation in pitch occurs as the singer modulates their airflow and vocal cord tension, resulting in a richer sound that can enhance emotional delivery. Understanding vibrato is essential for classifying operatic voice types, as it influences the overall timbre and stylistic characteristics of different vocal classifications.
