CMollDreiklang

CMollDreiklang denotes the C minor triad, a basic three-note chord in Western tonal music. It is built on the note C and consists of the notes C, Eb, and G. The interval structure is a minor third from C to Eb and a major third from Eb to G, producing an overall minor triad with a perfect fifth from C to G. In root position the chord is voiced as C–Eb–G, and it can also be voiced in first inversion (Eb–G–C) or second inversion (G–C–Eb).

In music theory and notation, the chord is typically written as Cm in English contexts, or C-moll in German-speaking contexts. The term Dreiklang emphasizes that it is a triad, consisting of three distinct pitch classes, as opposed to seventh chords or more complex harmonies.

Functionally, the C minor triad is the tonic chord in the key of C minor and serves as a fundamental harmonic sonority in that key. In major-key contexts, Cm can appear as a borrowed chord from the parallel minor, providing a melancholic or darker color. The triad is widely used across classical, pop, and jazz repertoires as a foundational harmonic element and as a building block for more advanced progressions.

Voicing and context influence its effect: in simple accompaniment it provides a stable, grounded sound, while in richer harmony it can be extended with sevenths, added tones, or cyclic progressions to create varied textures.
