Watch the Phraseology Rhythm online guitar lesson by Jeff Scheetz from Blues-Rock: Secret Sauce

When you're using minor 7th chords, like this arrangement, pay special attention to the changes and try to solo by playing those changes, referencing key tones in your solo.
You can outline the m7 chords by playing m7 arpeggios in your solo. You can also extend the arps to m9s and even alter them further to get some slightly outside sounding stuff going on.
Again, keep one ear on the rhythm and one ear on your solo!
