Watch the Taking It Out online guitar lesson by Jeff McErlain from 50 Blues Rock Guitar Licks You MUST Know

Let's add some chromaticism to our playing. The term chromatic means a note or notes outside of a scale. Diatonic means a note or notes within a scale. For example the note Ab is not in a C mixolydian scale (CDEFGABb) so it is chromatic. The cool thing is that a chromatic note falls between the whole steps in a scale, so if we add an Ab to the C major scale we have G, Ab, A, Bb. That gives us a series of half steps that we normally think of when we hear the term chromatic, it is also the chromatic note we will use on this cool lick.
