This exercise is from the Core Skills section on Bends.
So you can bend, but can you double bend? Double bending is actually very easy, and as the name suggests - you bend 2 strings at the same time.
Here we shall take a look at some double bends and how to do them. We explore doing double bends using different fingers. The aim is to show you double bends, and how they sound. It is also a practice exercise designed to help you develop dexterity and finger strength.
Notice that some bends are done using different fingers - others are played with support from fingers behind. Try them all out, some will be easier than others.
Note the direction of the bend is indicated by the arrow inside the dot! All the double bends are upwards in this example. You can do the same exercise by bending the strings downwards instead, once you are comfortable with your finger strength and control.
Practicing bends with your weaker fingers in particular helps build strength and dexterity. Don't skip the little finger - it usually needs more practice than your other fingers!
Double bends sound great - they can be dropped into solos with ease, and are often used to move between chord sequences. Experiment and have fun!
NB... If you are ever bending the low E or high E strings remember that guitars have narrow neck edges, so bending too far will pull the string off the fretboard. For this reason most people always bend upwards on the top string, and downwards on the lowest string.
