Here is a pair of classic endings for a blues in A, each performed in fifth position. The first tag applies a triplet-based bending pattern to each
of the top three strings and ends with a chromatically-ascending dominant seventh (˜ 9) shape, culminating with a tremolo-picked A7(˜ 9) chord.
The blues tag that follows uses a handful of descending double-stops to set up a climatic A9.
Blues endings can also be varied by using different arpeggiation techniques to double- and triple-stops, adding microtonal bends, and the like.
Run your fingers through this next trio of blues tags, then try creating some of your own by mixing up the aforementioned techniques.
