Harmonic Function

The C minor sixth chord commonly functions as the tonic (I) in C major/minor. Its harmonic role varies by key — in major keys it provides subdominant or supertonic color.

The minor sixth chord adds a major sixth to the minor triad. It has a bittersweet quality, slightly brighter than a plain minor chord, widely used in jazz and popular music. The C Minor Sixth Chord specifically contains 4 notes: C, D♯, G, A (formula: 1-♭3-5-6). On piano, C-rooted chords sit entirely on white keys in their basic triad form, making them the first chords most students learn. Pop, folk, and singer-songwriter music heavily use C-rooted chords because open-position guitar voicings and piano shapes are immediately accessible.
