#Fingervibrato is #vibrato produced on a string instrument by cyclic hand movements. Despite the name, normally the entire hand moves, and sometimes the entire upper arm. It can also refer to vibrato on some woodwind instruments, achieved by lowering one or more fingers over one of the uncovered holes in a trill-like manner. 

This flattens the note periodically creating the vibrato. weki  #Guitarvibrato In its pure form, vibrato is usually achieved by twisting the wrist rapidly to bend the note slightly, moving to and from the starting pitch. 

The speed of the vibrato oftentimes has a great effect on the way the note is perceived, with faster vibratos commonly adding tension and stress, while slower vibratos produce a more lyrical sound. The slowest of vibratos can be used to imitate a bowed instrument "growing" a note after its initial inception. Even though this effect refers to volume in bowed instruments, having a pitch variation that follows the same structure of the volume variation in many situations can have the same effect for the listeners. 

 In contemporary music, finger vibrato is also routinely used by classical guitarists on longer notes, to create an impression of a longer sustain. The technique is also used by jazz bassists to add depth of tone.
