How many sharps or flats does G Harmonic Major have?

What is the relative minor of G Harmonic Major?

What is the parallel minor of G Harmonic Major?
The parallel minor of G Harmonic Major is G Minor. "Parallel" means same root, opposite mode — the third, sixth, and seventh are all a half-step lower in the minor version. Modal interchange (borrowing chords from the parallel key) is one of the most useful tricks in pop and jazz writing.

The note names, intervals, fingering, and harmony on this page are drawn from the established body of Western music theory and verified against the conventions below — the same fundamentals taught in conservatories and music programs. We list categories of source material rather than individual titles, and reference the standards themselves rather than any single edition.

  • Standard music theory texts — Widely taught fundamentals of pitch, rhythm, and notation.
  • Western tonal harmony conventions — Established rules for chord construction, voice leading, and key relationships.
  • Interval and chord construction standards — The conventional spelling of intervals, triads, sevenths, and extensions.
  • Scale and mode theory — The common derivation of major, minor, pentatonic, blues, and modal scales.
