Parallel and Relative Keys

Every harmonic major scale has two close cousins. The parallel key shares the same root note but flips the mode (major ↔ minor). The relative key shares the exact same notes and key signature, but starts on a different tonic — three semitones down. Both relationships matter for songwriting: borrowing chords from the parallel key adds emotional color, and pivoting to the relative key is a smooth way to change the mood of a section without changing keys on paper.

Parallel key: Gb Minor Scale — same root note (Gb), opposite mode. The third, sixth, and seventh degrees shift by a half-step. See also the Gb Minor Chord.

Relative key: Eb Minor Scale — same key signature, different tonic. Gb Harmonic Major and Eb Minor use the same seven notes; the difference is which note feels like “home.” See also the Eb Minor Chord.
