Vibrato is yet another way the guitar imitates the human voice.
Only choir boys sing with a pure, unaffected sound. Almost always, singers add life and emotion to their melodies with a subtle wavering of pitch that we call vibrato . You should feel your wrist and forearm helping the rocking vibrato motion. Listen to B.B. King - the master of vibrato. Practice the vibrato at slow, medium and fast speeds and try maintaining an even vibrato throughout the duration of the affected note.
