C Aeolian

The C Aeolian mode — C D Eb F G Ab Bb — shown across the guitar neck.

Swipe the neck sideways to see the higher frets.

C Aeolian is the natural minor — same seven notes, same order. The mode name describes which chord you treat as home, not a different set of notes.

The tool shows this from its parent key, Eb major, with C marked as where Aeolian begins, the same seven notes centered on Eb.
