Augmented chord construction

Construction of the augmented triad.

When building a augmented triad chord we pick every other note in the augmented scale.

  • The augmented scale intervals: 1, #2, 3, #4, #5, 7.
  • The augmented chord intervals: 1, 3, #5.
  • 1 -> 3 = major third (3).
  • 3 -> #5 = major third (3).
  • 1 -> #5 = augmented fifth (#5).

Construction of the C augmented triad

The C augmented scale consists of the notes C D# E F# G# B and thus the C augmented triad is built of the notes C, E and G#.

  • The interval distance between the notes C and E is a major third (3).
  • The interval distance between the notes E and G# is a major third (3).
  • The interval distance between the notes C och G is a augmented fifth (#5).
