Vibrato is a musical effect consisting of a regular, pulsating change of pitch. It is used to add expression to vocal and instrumental music. Vibrato can occur spontaneously through variations in the larynx when singing. The vibrato of a string instrument and wind instrument is an imitation of that vocal function. Vibrato is typically characterized in terms of two factors: the amount of pitch variation ("extent of vibrato") and the speed with which the pitch is varied ("rate of vibrato") .
There are three main components of vibrato: pitch, volume, and timbre. Pitch is the note that the vocalist is singing, volume is the strength or intensity of that note, and timbre is the tone or distinct sound of that note. In addition to the pitch, you will also hear that the volume and fullness of the note also wobbles with vibrato singing. This results in a fullness and richness in your singing that sounds very exciting.
Vibrato can be heard in most styles of music, including pop, classical, and jazz. In pop music, the vibrato usually starts somewhere in the latter part of the note. Vibrato can bring vitality to the voice and stylistic variation to a song, making the voice stand out at the end of a sung phrase. However, it is important to use vibrato in moderation and not to exaggerate it, as it can sound unnatural. Vibrato is not something that needs to be added to the tone, as it exists as an important element of resonant vocal timbre. When good tone production, resonance, placement of sound, breath management, and relaxation are in place, vibrato naturally results or occurs in the singing voice.
