- The IV Chord (Subdominant): This chord creates a sense of gentle movement away from the tonic. In C major, the IV chord is F major.
- The V Chord (Dominant): This chord creates the strongest pull back to the tonic. It has a distinctive tension that yearns for resolution. In C major, the V chord is G major.
