Had my lesson.
We're talking a straight blues, I've already been practicing arpeggio exercises though it for some time.
I explained my mind goes blank and I lack any creativity when it comes to improvising.
My teacher showed me how much mileage you can get out of a simple phrase.
Reason for the blues, is I've been working on improvising for ages, and feel like I'm getting nowhere, as I've already got the progression under my fingers from the exercise build on that.
I doubt I'll be at my teachers level anytime soon, but was fascinating watching him taking a simple phrase, and really making the most of it. Then another phrase, then mixing the two together.
The analogy he gives me, is being like a child playing with building blocks, I have the blocks, now I need to put it together and mess around with them, experiment and have fun.
My head's been all over the place lately, so not feeling it, getting narked off, and over thinking it didn't really help things.
