The Vibrato Technique

To give a guitar note a singing, vocal quality, you use a technique known as vibrato, where the pitch is slightly moved back and forth to create a singing quality like a human voice.

Vibrato involves a modulation of pitch created by moving the string. There are two basic types of vibrato:

1. Classical vibrato involves moving a left-hand fingertip back and forth along the string length, causing the string to tighten and loosen slightly, which causes the pitch to move. Classical vibrato is easier to apply to nylon-string guitars than to steel-string or electric guitars because the nylon-string tension is lower. This vibrato makes the pitch both rise and fall above the original note.
2. Vertical vibrato involves moving the string back and forth in a motion parallel to the frets. This vibrato is used in popular guitar styles, such as blues and rock. The pitch only rises compared to the original note
