C Minor Chord
Dark and sad sound
Cm is most commonly played as a movable barre chord — the easiest shape sits at fret 3 (C Minor Barre).

What is a Cm chord?
A minor chord stacks the root, minor third (3 semitones — one fret lower than the major third) and perfect fifth. That single half-step shift in the third is the entire difference between major (bright, resolved) and minor (dark, melancholy). Minor chords are the natural anchor of minor-key songs and provide emotional contrast in major-key progressions as the vi chord (relative minor).
Notes in the chord: C – D# – G
Intervals: Root, b3, 5 (measured from the root)

When to use a minor chord
Cm is the home (i) chord of C minor and the relative minor (vi) of D# major. Minor chords carry sadness, longing, drama and tension across every genre — from Dorian-mode rock (Eleanor Rigby, Wicked Game) to natural minor pop ballads to flamenco and metal. The vi-IV-I-V progression (Am-F-C-G in C major) is one of the most-used emotional progressions in modern pop. Minor chords also act as substitute tonics — vi can stand in for I to weaken the sense of resolution.
Common substitutions for Cm
- •Minor 7th — adds the b7 for a smoother, jazz-blues feel
- •Minor 9th — adds tension and color without losing the minor character
- •Diminished — replaces the 5th with a b5 for darker, more unstable tension
- •Sus2 — keeps the open quality but removes the gendered (major/minor) third
