Lesson Understanding Intervals
Diminished & Augmented 5th
♭5 and ♯5 — the color tones
Prove it — just do the practice exercise.
C → Gb 6 semitones
- C
- root
- Gb
- ♭5
Diminished 5th (♭5) = 6 semitones
→ Same as the tritone! Found in m7♭5 (half-diminished).
Augmented 5th (♯5) = 8 semitones
→ Floating sound. Found in augmented triads.
Example:
C → Gb = diminished 5th
C → G# = augmented 5th
These intervals create color and tension.
