One way to expand the musical possibilities of a chord progression is to invert some of the chords in order to create both harmonic interest and melodic movement in the bass line.

Enjoy this famous example, first, without chord inversion (all chords in root position)…

Now with some chords inverted, creating a linear bass line that descends smoothly and melodically through the changes…

BTW, do these changes sound familiar? If they ring a bell, please comment below!
