Functional relationships

These chords are where this one most naturally comes from and resolves to inside a key.

Relative minor G minor

The relative minor uses the same notes and key signature, so it works as a calmer, darker home base.

Parallel minor A sharp minor

The parallel minor keeps the same root note but lowers the third, giving the same key a darker, sadder sound.

Dominant F

The dominant is a fifth above the root, and it builds tension that pulls strongly back to this chord.

Subdominant D sharp

The subdominant is a fourth above the root (a fifth below), and it usually leads on to the dominant or back home.

Tritone substitution B seven

The tritone substitution stands in for this chord's dominant with a dominant seventh a half step above the root, which slides down by a half step to resolve here.
