Inversions
Put a different note on the bottom.
Bottom note is the boss
An inversion is the same chord with a different note in the bass. It changes how the chord leans and where it wants to go next.
The three of them
root 1 3 5 — settled, home first 3 5 1 — lighter, leading second 5 1 3 — the most restless of the three
Why it matters
Bass movement is the hidden melody of every progression. Inversions let the bottom line move in steps instead of leaps.
