Reference : inversion of intervals
To invert an interval, place the lower note one octave higher or the highest note an octave lower:
In the following tables you can see how an interval is transformed when inverted:
| Interval: | after inversion becomes: |
|---|---|
| 2nd | 7th |
| 3rd | 6th |
| 4th | 5th |
| 5th | 4th |
| 6th | 3rd |
| 7th | 2nd |
| Interval quality: | after inversion becomes: |
| major | minor |
| minor | major |
| augmented | diminished |
| diminished | augmented |
| perfect | perfect |
The inversion of intervals is very useful in analyzing sixths and sevenths. See Identifying Intervals by Using Inversions.
