Watch the b7, Bend to 7, 1 online guitar lesson by Brad Carlton from Guitar Lab: Bulls Eye Blues Riffs

Example 7 takes the previous example and applies a bend of the b7 up to the 7. You will then place the pick against the string to silence it before you release the half step bend. Then complete the riff by striking the 1. This move is very common in blues guitar and can be applied to any area in a scale that encompasses a major second interval (one whole step).
