One of the challenges I have with memorizing licks, scales, etc., is that it usually takes me a few attempts before I get them right. Playing a lick, scale, arpeggio, pattern, whatever, repeatedly doesn't help because after a few repetitions I nail them. Similarly, playing a lick through the circle of fifths, descending half- or whole-steps doesn't really help because then I've got the pattern in my head. This includes things I've worked on for years. Of course, this is a big problem in a performance setting. Any tips? It doesn't sound very efficient to play a lick once and come back to it 5 minutes later.
