G Harmonic Minor Piano Scale
The key of G minor and B flat major are related and share the same key signature of 2 flats, B flat and E flat. G minor is known as the relative minor of B flat major; B flat major is known as the relative major of G minor.
G is the 6th note of the B flat major scale. The 6th degree of any major scale is always the note which represents the related minor key.
As the keys of B flat major and G minor are related to each other, they both share the same key signature of 2 flats. Therefore the scale of G minor, in its most basic, natural form, will share exactly the same notes as B flat major but rather than beginning and ending on B flat (B flat major) will begin and end on G (G minor).
B flat major: B flat C D E flat F G A B flat
G Natural minor: G A B flat C D E flat F G
To change the natural G minor scale into the harmonic G minor scale
Take the notes of the natural G minor scale and raise the 7th degree, F, by one semitone or half step to F sharp. There will still be 2 flats, Bb and Eb, in the key signature but now F sharp will appear as an accidental on the music staff.
G Harmonic Minor Scale:
