These two examples show how pull-offs and open strings can combine to create very fast patterns creating a sound that works well over an A dominant 7th chord with a lowered ninth and flat 13, or an E minor 7b5 chord (or changes including both of them). The pull-offs are executed with the 4th and 1st fingers, and the other fingers support. Gently pivot your wrist, keeping your thumb anchored in the middle of the back of the neck. The fingering remains 4, 1, 0 throughout. For a change, vary the order of the notes, using a pair of hammer-ons (fingered 0,1,4) or a pull-off and a hammer-on (fingered 1,0,4 or 4,0,1). The first example uses swing eighth notes grouped in threes.
