Minor 6th vs Major 6th

The sixth intervals are wide leaps that often trip up beginners. Because they are the inversions of the thirds, they carry similar emotional weight but span a much wider distance.

What is the difference?

A minor sixth (m6) spans 8 half-steps. It sounds tragic, romantic, and yearning. A classic example is the opening leap in the theme from "Love Story" or the song "In My Life" by The Beatles.

A major sixth (M6) spans 9 half-steps. It sounds open, sweet, and comforting. The most famous example is the first two notes of the "NBC Chimes" or "My Bonnie Lies Over the Ocean".

The inversion trick

If you struggle to hear sixths, remember that they are upside-down thirds!

If you flip a minor 6th upside down, it becomes a Major 3rd.
If you flip a major 6th upside down, it becomes a Minor 3rd.

If you can hear that "happy" major third quality hidden inside the interval, you are listening to a minor 6th!

Practice strategy

Drill these two side-by-side. The major 6th will always feel slightly wider, brighter, and more "resolved" than the yearning, tragic pull of the minor 6th.
