Chord & FretHarmonic field of A minor
The harmonic field of A minor is the set of seven chords born from the A minor scale — one on each of its notes. The table shows each in two versions: the triad (the three-note chord) and the seventh chord (the same chord with a fourth note, the seventh, that enriches it).
Notes: A – B – C – D – E – F – G| Degree | Triad | Seventh | Function |
|---|---|---|---|
| i | Am | Am7Am7Am7Am7 | tonic |
| ii° | B° | Bm7b5 | subdominant |
| III | C | Cmaj7Cmaj7Cmaj7Cmaj7 | tonic |
| iv | Dm | Dm7Dm7Dm7Dm7 | subdominant |
| v | Em | Em7Em7Em7Em7 | dominant |
| VI | F | Fmaj7Fmaj7Fmaj7Fmaj7 | tonic |
| VII | G | G7G7G7G7 | dominant |
The roman numerals mark the chord's position in the scale: I is the first degree, V the fifth. Uppercase = major chord; lowercase = minor; ° = diminished.
Tonic chords stabilize and rest; subdominant chords prepare motion; dominant chords build the tension that asks for resolution.
This is the natural-minor field. In practice the v often becomes V (major) or V7 — borrowed from the harmonic minor — to create the leading tone that pulls back to the tonic.
