What is "vocal agility"?

Vocal agility refers specifically to the skill and capability of executing rapid passages of music smoothly and accurately. This involves the ability to maneuver quickly between notes, which is a crucial skill for performing intricate musical pieces that require fast, fluid vocal runs or ornamentations. It allows singers to deliver performances that are not only technically proficient but also stylistically expressive, particularly in genres where embellishments and quick melodic variations are prevalent.

The other choices highlight important aspects of vocal performance. Singing in different vocal styles denotes versatility, which is important but does not specifically define agility. The range of pitches a singer can reach pertains to the overall capability of the voice in terms of pitch extremes, and while critical for a singer, it does not reflect the nuance of agility in executing quick, smooth transitions. The strength of a singer's voice refers to the volume and power behind the sound, which, while valuable, is distinct from the dexterous quality emphasized in vocal agility.
