C minor — notes and structure

The Cm chord has a darker, sadder sound than its major counterpart, thanks to the lowered third.

The Cm minor consists of the notes C, E♭, G. Its interval structure is R–3–5 — the root, then each chord tone stacked above it. This is the same chord you see in the interactive finder above, drawn on the piano keyboard with the root circled and every chord tone labelled.

Cm stacks a minor third (E♭) and a perfect fifth (G) above the root C.
