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 a 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!
