Vibrato is a technique where the left hand moves the fretted string rapidly up and down small distances towards adjacent strings. Vibrato helps to sustain a note and can make that note more interesting, and is mostly used on long notes or at the end of a phrase. Vibrato is indicated by a wavy line () written above the note and tab. Vibrato can be applied to any fretted note and played by any left hand finger.
The speed of the vibrato depends on the pitch of the note, e.g., the vibrato of a low note is played slower than that of a high note.
Example 190 uses the vibrato () on the indicated notes.
The vibrato shake is another technique to create a vibrato sound by rapidly shifting backwards and forwards from the playing note to the next highest fret. The following example features the vibrato shake.
