bending on the low strings
Here Brett is bending the fifth string, again using his fourth finger with all fingers behind it for support. If you’ve not tried fourth-finger string bends, Brett is a perfect inspiration to draw from as his technique allows him to use whatever finger he needs to bend with, as opposed to favouring only, say, the second or third fingers (most common choices with guitarists). To develop your technique, explore semitone (one fret’s worth) and tone (two frets’ worth) bends on the higher strings first before moving to the thicker middle strings and then the thick low strings. After a few weeks, you’ll be a more versatile guitarist.
