UPDATE - added a PDF that shows a bunch of examples
You can never have too many pentatonic licks. Ever.
But, in the real world what usually happens is first you learn the little box shapes, okay cool, then maybe some of the other shapes, the ones that start on notes other than the root, and then.....it kinda tapers off.
What can happen after a while is you just keep playing the same box-shape licks over and over. And over and over and over. Or maybe you find another pattern that fits under your fingers, but you only have one or two familiar patterns you default back to or they are the ones that fit under
everybody's fingers. I mean, I certainly have never done that. Of course not. Never. Okay, I totally have.
Then the question becomes - Well, how do I make/invent/discover/create new material anyway? If only there were some repeatable, step-wise process one could use to generate new licks and phrases for use in solos. Oh what a great world it would be...
Of course there is.
And I am going to show y'all one.
