12.5Find the dominant of any destination

The rule is simple:

Take the chord you want to arrive at. Go up a perfect fifth from its root—or down a perfect fourth. Make that chord dominant 7.

Want to arrive at:

Am

Dominant = E7

Want Dm:

Dominant = A7

Want G:

Dominant = D7

Want F:

Dominant = C7

Want Em:

Dominant = B7

This immediately reconstructs much of your original chord chart.
