Sixths

Sixths can be major, minor, augmented or diminished. Below you can see that the number of steps determines the quality of the interval:

Major sixth, 4 1/2 whole steps or 9 half steps:

major sixth

Minor sixth, 4 whole steps or 8 half steps:

minor sixth

Augmented sixth, 5 whole steps or 10 half steps:

augmented sixth

Diminished sixth, 3 1/2 whole steps or 7 half steps:

diminished sixth

Identifying sixths

The easiest way to identify the quality of a sixth is by inverting the interval and identifying the resulting third. For example, the interval C#-A#:

6th
A major 6th becomes a minor 3rd when inverted
