What is the inversion of a diminished 5th?
When augmented intervals are inverted they become diminished and vice versa, diminished intervals when inverted become augmented. For example, a diminished 5th when inverted becomes an augmented 4th and vice versa.
What is the inversion of a perfect 5th?
Summary
| Number of half steps | Common Spelling | Inversion |
|---|---|---|
| 4 | Major Third (M3) | Minor Sixth (m6) |
| 5 | Perfect Fourth (P4) | Perfect Fifth (P5) |
| 6 | Tritone (TT) | Tritone (TT) |
| 7 | Perfect Fifth (P5) | Perfect Fourth (P4) |
How do you calculate a diminished 5th?
Since C to G is a perfect fifth (7 semitones), C to Gb would be a diminished fifth (6 semitones). B to F is also a diminished fifth (since B to F# is a perfect fifth). Minor intervals can also be diminished by subtracting a half step. Minor intervals can also be diminished by subtracting a semitone.
What is the inversion of augmented fourth?
The inversion of the augmented fourth is the diminished fifth.
