Contrary Chord and Bass Motion

This Blog demonstrates the movement of chord structures and bass notes moving in contrary motion against each other.      

The example below moves through full chromaticism using the tonality of major chords... of course it is encouraged that the composer experiment with varying chord types and combinations within this type of movement for it is quite interesting.   

In addition, notice that the chords and bass notes begin in unison move in opposing directions and meet in unison in the middle at the interval of a diminished 5th and then split again to eventually resolve in unison once again.
