Major sixth

[2]A commonly cited example of a melody featuring the major sixth as its opening is "My Bonnie Lies Over the Ocean".

In the common practice period, sixths were considered interesting and dynamic consonances along with their inverses the thirds.

In medieval times theorists always described them as Pythagorean major sixths of 27/16 and therefore considered them dissonances unusable in a stable final sonority.

The septimal major sixth (12/7) is approximated in 53 tone equal temperament by an interval of 41 steps or 928 cents.

In just intonation, the most common major sixth is the pitch ratio of 5:3 (playⓘ), approximately 884 cents.
