Cm

— About this chord

Cm (C minor) has a dark, melancholic tone with a wistful, introspective feel, often described as somber yet expressive. A base-level essential in rock ballads, indie and alternative pop, blues progressions, and film-score underscoring, it can also color jazz harmony with moody sophistication. On guitar it’s beginner-friendly in open shapes but frequently played as a barre chord; on piano it’s straightforward (C–Eb–G), with Cm7/Cm9 adding richer, dreamy color. Commonly used for minor-key tonic grounding, it sets up iv–V or i–VI–VII movements, creating tension that resolves poignantly; some voicings can hint at Eastern or cinematic noir vibes. Also searched as Cmin or C minor chord for sad, emotional, dramatic, and atmospheric styles.
