Doubly augmented second

In music theory, a doubly augmented second is an interval that has two whole steps united states of america (tones united kingdom).

The doubly augmented second requires that:

  • The interval must be an second interval (two note names between the first and the last).
  • The interval must have two whole steps.

What does a doubly augmented second look like?

Here is an example of a melodic doubly augmented second (two music notes in a melody) and a harmonic doubly augmented second (in a chord):

How to recognize a doubly augmented second?

Rule of music theory: All intervals in a major scale starting with the tonic (degree I) are either major or perfect, and only unison, octave, fourth and fifth are perfect (the others are major).

Example with the interval C / D♯♯:

Let's take the C major scale to have C as the tonic:

C major scale

From the rule stated above, the interval C / D is a major second, so the interval C / D♯ is a augmented second, and so C / D♯♯ is a doubly augmented second.

Inversion of the doubly augmented second

The inversion of the doubly augmented second is the doubly diminished seventh.

Here is an example of a doubly diminished seventh:
