How do you guys go about drilling into the gray (grey ;-)) matter so they are usable in improvising. Thanks in advance. My ADD is winning right now.
One thing that I've found useful sometimes is to actually analyse a lick or a phrase or part of a melody - just about any sequence of notes. I have many pages of printed music that have my pencil markings on them.
When I say analyse, I just forget about the mechanics and the notes, and look closely at the degrees of the scale that comprises the sequence of notes. I'm just gonna grab one at random and work through it. This is a short lick, and it's all ascending.
Flat 3, 3, 5, 6, 1 (octave up), 1, 1, Flat 3 (octave up). That's just 8 notes, but without the distraction of counting or timing they look pretty simple. That's one idea - just forget the duration of the notes, concentrate on the sequence.
Another aspect of analysis is the intervals - same sequence as above, starting from the first note; half-step, minor third, whole step, minor third, unison (same note again), unison, minor third.
Another thing to analyse is which notes you are bending - Flat 3 to 3 (half-step), 4 to 5 (whole step), Flat 7 to Root (whole step); are the common ones.
If you do this sort of thing with the licks that you are actually trying to learn or memorise, you may start to see similarities, or little bits that occur in different places of different licks. And then you might be able to start building your own licks out of those fragments.
And while you are exercising your brain with the analysis, it may help you with memorising.
Plus what Craig and Mike and all the others said above.
