Diminished licks are a great way to spice up your solos in a more jazzy jump blues tune. A diminished chord is an unstable passing chord that consists of a symmetric stack of flatted third intervals. These chords have found their way into your standard blues progressions, first and foremost in bar six, where you are moving from the IV chord back to the I chord in bar seven. These diminished chords give you some extra soloing options, like the use of the half whole diminished scale. You could also just target the diminished chord tones to get that uptown jazzy sound which always raises some eyebrows.
