What is it?
When a string is bent, its pitch goes up.
When you pull the string back to its unbent position you have a "release"
String bending has now become one of the most widely used techniques in most guitar styles, from country- blues to heavy metal.
You need to control string bending in order to make your playing sound professional.
How to play it
Place you third finger at the 7th fret and the second finger at the 6th fret on the same string, the third. Your second finger should be behind the third to help push up the string.
Put your index finger on the other strings without pressing down, this serves to mute the other strings.
Put your thumb on the neck of the guitar, this is to give strength and stability to the hand.
An up arrow indicates that a string is to be bent, the symbol "full" gives the target pitch. This is a "two fret", also known as a "whole step" or "full step". In this bend you play the 7th fret but the destination pitch is the 9th fret.
An arrow back down means to release a bend and return the string to its unbent position.
Do not lift up, but rather, keep pressure down on it while you pull the string back to its unbent position.
In the example below hold fixed the first finger on the fifth fret and play the bending on the seventh fret.
In the example below play these bending on notes of pentatonic scale.
The same notes of previous exercise but here with realase.
