7th Chord Ear Training
Seventh chords add a fourth note to basic triads, creating richer, more complex sounds. They are the foundation of jazz, R&B, neo-soul, and modern pop harmony. Learning to hear the difference is essential.
The three main seventh chord types
- Major 7 (Maj7): Root + M3 + P5 + M7. Sounds dreamy, lush, and sophisticated. Think smooth jazz or bossa nova.
- Minor 7 (min7): Root + m3 + P5 + m7. Sounds warm, mellow, and slightly melancholic. Common in neo-soul and R&B.
- Dominant 7 (dom7): Root + M3 + P5 + m7. Sounds bluesy, funky, and creates tension that wants to resolve. The backbone of blues and funk.
How to tell them apart
Focus on two dimensions: the triad quality (major vs minor) and the seventh type (major vs minor):
- Maj7: Happy triad + sweet top note = dreamy.
- Dom7: Happy triad + bluesy top note = funky tension.
- Min7: Sad triad + warm top note = smooth melancholy.
The dominant 7th is the trickiest because it has a major triad but a minor seventh — this "mismatch" gives it its characteristic bluesy tension.
Practice tips
- Start with just Maj7 vs min7 — these are the most common in modern music.
- Add Dom7 once you're comfortable with the first two.
- Use piano sound for clearest results — seventh chords are easier to hear on piano than synth.
- Practice in both ascending (arpeggiated) and harmonic (all at once) modes.
