Functional relationships
These chords are where this one most naturally comes from and resolves to inside a key.
The relative minor uses the same notes and key signature, so it works as a calmer, darker home base.
The parallel minor keeps the same root note but lowers the third, giving the same key a darker, sadder sound.
The dominant is a fifth above the root, and it builds tension that pulls strongly back to this chord.
The subdominant is a fourth above the root (a fifth below), and it usually leads on to the dominant or back home.
The tritone substitution is a dominant chord a tritone away that shares the same tension, so it can stand in for this chord and resolve the same way.
