Here's a nice little fourth / pentatonic type intervalic ii-V7 pattern, a la Woody Shaw, that slipped into my fingers the other day as I was doing my saxophonic due diligence.
A quick analysis of the first line reveals that on beats 3 & 4 and 1 & 2 of measures one & two respectively, there's a brief tonality shift into B Major, or one half step below the target key, C.
Beats 3 & 4 of measure two are an altered four note grouping, relative to the dominant (G7), leading back to the targeted tonic chord C minor (or Major).
There are a bunch of ways you could reharmonize this line, superimpose it over different key centers, etc., but I haven't messed with that so far.
In any case, it's a cool device for momentarily steppin' "out", and then slidin' back "in".
Have fun!
