Okay, so your reading a tab you see a bunch of numbers and hey, you can handle that but then suddenly, with no trace of warning Boom! there's a weird b thing! Aaaaaghhh!!!  What do you do?  Where are you?  What's your name?  In this lesson you will learn what bending is and how to bend, (yes that's what b means.)

First off let's take a look at the correct way to bend on the chord diagram bellow.

You may notice the blue dot's behind the black one.  If you didn't get your eyes checked.  They are support fingers to give your bend better sound quality.  So do that: put one of fingers on the 4'th fret one on the 3'rd and one on the 2'nd of the G string and push the string.  It takes a while to get right but like everything else on here it is well worth it in the long run.
 

Okay, let's take a look at a Tourniquet riff from the honkin' cool song "Twilight" off their old Vanishing Lessons album.

Bending is mainly used in rock, blues, metal and country music, (although it doesn't ever sound any good in the latter.)  It's a technique that will vastly enhance your soloing for the better.  So what are you staring at your computer for, go practice!!!
