Harmonic field of C minor
The harmonic field of C minor is the set of seven chords born from the C 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: C – D – Eb – F – G – Ab – Bb| Degree | Triad | Seventh | Function |
|---|---|---|---|
| i | Cm | Cm7Cm7Cm7Cm7 | tonic |
| ii° | D° | Dm7b5 | subdominant |
| III | Eb | Ebmaj7Ebmaj7Ebmaj7Ebmaj7 | tonic |
| iv | Fm | Fm7Fm7Fm7Fm7 | subdominant |
| v | Gm | Gm7Gm7Gm7Gm7 | dominant |
| VI | Ab | Abmaj7Abmaj7Abmaj7Abmaj7 | tonic |
| VII | Bb | Bb7Bb7Bb7Bb7 | 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.
