This exercise is from the Core Skills section on developing Speed Techniques.

This is a great little bending lick. It sounds good, it works with most styles of music, and integrates well into solos. The lick is using the E natural minor / pentatonic minor scale. But you can apply the same technique to any scale with great effect.

Notice that we are using the same picking trick from the previous exercises. i.e. Place the pick between the 2 strings being played (only 2 strings are used in this lick). Pick upwards first, and then downwards. You don't have to do it this way, you can pick anyway you prefer - especially in this part of the lick, as there is enough time between notes to pick it a number of ways. But for most fast licks on adjacent strings, this is a more economical way to pick quickly. Get into the habit now, and it will pay off for you later.

As for the little pull off, notice it is played with an upstroke, as is the bend on the next sting. This sort of breaks the doctrine of alternate picking (that ultimate speed is achieved by constant down / up strokes no matter what note comes next). However, in licks like this it is best to play the way shown here. In actual fact, it's not really breaking the alternate picking 'law'. The note that is 'pulled off to' here (i.e. the note between the pull off and the bend) would be played as a downstroke if the preceding note was picked normally, and not a pull off.

Don't be afraid to use pull offs or hammer ons to play notes instead of picking them. Often the fastest solos use a mix of both to get blistering pace.

The lick is very short, and repeats. Focus on getting the bends up to the right pitch quickly. This lick takes good string control and timing, but once you get the hang of it you'll find it will be a worthy addition to your repertoire.
