- V7/ii – Leading to the ii chord
- V7/iii – Leading to the iii chord
- V7/IV – Leading to the IV chord

Common Progressions Using Secondary Leading Tone Chords
Progression 1: ii – V7/ii – V
This progression emphasizes the secondary dominant to the ii chord, creating a smooth and strong resolution back to the tonic or other chords in the key.
Progression 2: I – V7/iii – iii – V7/IV – IV
This sequence introduces multiple secondary leading tone chords, adding complexity and richness to the harmonic movement.
Progression 3: I – V7/V – V – V7/ii – ii
Using the V7/V to lead to the V, then moving to the ii chord, this progression showcases the power of secondary dominants to create a dynamic harmonic flow.
