In this video, I'm going to show you an easy trick you can use to add passing chords to your progressions.

This is a simple device but can be very powerful if used tastefully and creatively.

The idea is to approach the target chords chromatically, whether that be a half-step above, or below. You can even push it to several half-steps away. You want to try and land on the target chord on the beat, and use the chromaticism to build tension.
