Unison String Bending on an Electric Guitar

Listen how unison bends sound with a distorted guitar:

The difference between a straightforward string bending and the unison bending is that unison bends are played with two notes on two adjacent strings, the upper string remains in its place, while the lower one is to be bent to the point when they both have the same pitch.

The most comfortable pair of strings for performing unison bends are the 2nd and 3rd string.

For instance:

You can play the 2nd string at the 5th fret and the 3rd one at the 7th fret, bend the latter to make it sound one full tone higher (as a note would sound at the 9th fret), so their pitches merge.

Note that you don't need to actually press the string at the 9th fret.

To make a full tone unison bend on the 1st and 2nd string pair, press the 1st string at the 5th fret and the letter (that you bend) at the 8th.

• When playing bends, I recommend you to put the thumb of your fretting hand above the guitar neck as I did in the picture.

• As well as use at least two fingers to shift a string, let's say if you intend to bend a string with your ring finger, add the middle one to help him.

This will make bending so much easier!
