7ths: Major & Minor


Sevenths are usually either major or minor. They can be "sweet" sounding and peaceful - or "active" and dissonant. When we explore chords and chord progressions we will see that sevenths very often determine the direction and progression of the harmony.

A major seventh consists of a P5 + M3; for example C to B is a major sixth (C to G = a P5 + G to B = a M3). (I tend to think of a major seventh as being a half step from the octave.)

A minor seventh consists of a P5 + m3; for example, C to Bb is a minor seventh (C to G = P5 + G to Bb = m3.) (I tend to think of a minor seventh as being a whole step from the octave.)

MAJOR SEVENTHS

Below are some examples of major sevenths. Each one consists of a
P5 = M3:

MINOR SEVENTHS

Below are the same intervals EXCEPT they have been changed from major sevenths to minor sevenths. They each consist of a P5 + m3:

MAJOR & MINOR SEVENTHS

The sevenths below are either major or minor.

  • Major = M
  • Minor = m

The major sevenths consist of a P5 + M3 - the minor sevenths consist of a P5 + m3.
