Passing, Approaching, and Slinky Snakes
One way to break out of the same old rut is to start adding some passing notes, approach notes, and slinky or angular lines into your phrasing. Check out our run of the mill minor pentatonic pattern.
You can do a lot with this pattern but, really, unless you start superimposing it against other harmonic structures, it will start to sound a little stale after a while. But Try throwing in some approach tones 1/2 step below the scale tones and 1 whole step above the scale tones. This is a typical strategy employed by players like Mike Stern.
Taking this a step further, we can combine the approach notes and the passing tones that results in a much more complex note matrix:
