Interval Inversions
An interval is said to be inverted when one of the notes is moved up
or down an octave. In the example below, the minor third (b-d) becomes
a Major sixth when the b is moved up an octave.
Any interval can be inverted and the following table is always true for
interval inversions:
Original Interval |
Interval after Inversion |
1 (unison) |
8 (0ctave) |
2nd |
7th |
3rd |
6th |
4th |
5th |
5th |
4th |
6th |
3rd |
7th |
2nd |
This describes what happens to the interval quantity.
The next table shows the interval quality.
