Functional relationships
These chords are where this one most naturally comes from and resolves to inside a key.
Relative major
The relative major uses the same notes and key signature, so it works as a brighter home base.
Parallel major
The parallel major keeps the same root note but raises the third, giving the same key a brighter, happier sound.
Dominant
The dominant is a fifth above the root, and it builds tension that pulls strongly back to this chord.
Subdominant
The subdominant is a fourth above the root (a fifth below), and it usually leads on to the dominant or back home.
Tritone substitution
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.
