How the key of C minor works

C Minor carries three flats (Bb, Eb and Ab). The scale runs C–D–Eb–F–G–Ab–Bb, and stacking every other note of that scale builds the seven chords above — every chord tone comes from those same seven notes.

Eb Major is the relative major: identical key signature, identical seven chords. Treat Eb — the III chord here — as home base and you are in Eb major without changing a note.

The parallel major, C Major, keeps the same root but raises the third, sixth, and seventh — its signature shifts to no sharps or flats. Moving a section from minor to parallel major is one of the oldest brightness tricks in songwriting.
