Watch the Slide Vibrato online guitar lesson by Andy Aledort from Slide Guitar Power

Along with using glissandos, sliding up or down to a specific note, the technique that most evokes a vocalesque quality on slide guitar is vibrato. Repeatedly moving the slide back and forth (higher and lower) along the length of the string creates the sound of a slide vibrato. The width of this movement, as well as the speed, this is every player’s choice; just keep the center of the vibrato movement over the fret for proper intonation.
