Primary Triads (Chords) in the Key of A Minor

To find the primary triads, we build chords on 1st, 4th and 5th notes of the scale.

  • Chord i – A Minor: A C E 

A Minor Chord

  • Chord iv – D Minor: D F A

D Minor Chord

  • Chord V – E Major: E G# B

E Major Chord

Note that chord 1 and 4 are minor, while chord 5 is a major triad, just like in all other minor scales. This is because the 7th note, G# is raised in the harmonic scale.

Secondary Triads (Chords) in the Key of A Minor

 Here are the secondary triads in the key of A Minor, that are built on 2nd, 3rd and 6th degrees of the scale:

  • Chord ii° – B diminished: B D F#

B Diminished Chord

  • Chord iii+ – C Augmented: C E G#

C Augmented Chord

  • Chord VI – F Major: F A C

F Major Chord

And just like all other minor keys, the 2nd triad is diminished, 3rd is augmented and 6th is a major.

  • Chord vii° – G# diminished: G# B D

Building a chord on 7th note of a minor scale produces diminished triads, just like that in a major scale.

Extended Chords

 By using the notes of A Minor scale, we build four-note seventh chords.

  • A Minor-Major 7th: A C E G#
  • B Half-diminished: B D F A
  • D Minor 7th: D F G# C
  • E Dominant 7th (A7): E G# B D
  • F Major 7th: F A C E
  • G# diminished 7th: G# B D F
