How does a singer achieve vibrato?

Vibrato is a vocal technique characterized by a regular, fluctuating pitch that adds warmth and expression to the sound. Achieving vibrato involves making rapid changes in pitch or volume, which creates a natural fluctuation in the note being sung. This oscillation is usually controlled and produces a rich, resonant sound that enhances the overall musical performance.

The technique for producing vibrato primarily originates from the singer's ability to manipulate their breath support and control their vocal cords. As the singer allows the pitch to oscillate slightly, it adds dimension and emotion to the performance. This skill can be cultivated through exercises that focus on breath control and relaxation of the throat and vocal muscles.

The other options do not effectively explain how vibrato is produced. Shaking the head while singing does not contribute to vibrato; instead, it may create distractions or negatively affect the vocal quality. Holding notes longer is about sustaining a pitch rather than fluctuating it, while deep breathing before singing is important for overall breath support but does not directly lead to the production of vibrato without the subsequent pitch modulation.
