Lesson
Chord Quality: Major, Minor, Diminished & Augmented
Chord quality refers to the characteristic sound of a chord based on its interval structure. Major chords sound bright and happy. Minor chords sound dark and sad. Diminished sounds tense, and augmented sounds dreamy. This lesson trains you to instantly recognize these qualities.
Root + M3 + P5
Bright, happy, stable, resolved. Most common chord type. Example: C-E-G.
Emotional quality: Joy, triumph, confidence, resolution.
Root + m3 + P5
Dark, sad, melancholic. Common in ballads. Example: C-Eb-G.
Emotional quality: Sorrow, introspection, mystery.
Root + m3 + dim5
Tense, unstable, spooky, ominous. Used in passing chords, jazz. Example: C-Eb-Gb.
Emotional quality: Suspense, danger, unresolved tension.
Root + M3 + aug5
Dreamy, floating, mysterious, unresolved. Rare but distinctive. Example: C-E-G#.
Emotional quality: Surreal, otherworldly, ambiguous.
Recognition Strategy
- Stable or Unstable? Major/minor = stable; dim/aug = unstable
- If stable: Is it bright (major) or dark (minor)?
- If unstable: Is it tense/ominous (dim) or dreamy/floating (aug)?
Common Mistakes to Avoid
1. Confusing inversions with quality
A chord in first or second inversion is still the same quality - just different voicing.
2. Not listening to the 3rd
The 3rd interval (major or minor) defines the fundamental character of the chord.
3. Practicing too fast
Accuracy before speed. Get 95% on major vs minor before adding dim and aug.
