C Harmonic Minor Piano Scale
The key of C minor and E flat major are related and share the same key signature of 3 flats, B flat, E flat and A flat. C minor is known as the relative minor of E flat major; E flat major is known as the relative major of C minor.
C is the 6th note of the E flat major scale. The 6th degree of any major scale is always the note which represents the related minor key.
As the keys of E flat major and C minor are related to each other, they both share the same key signature of 2 flats. Therefore the scale of C minor, in its most basic, natural form, will share exactly the same notes as E flat major but rather than beginning and ending on E flat (E flat major) will begin and end on C (C minor)
E flat major: Eb F G Ab Bb C D Eb
C Natural minor: C D Eb F G Ab Bb C
To change the natural C minor scale into the harmonic C minor scale
Take the notes from the natural C minor scale and raise the 7th degree, B flat, by one semitone or half step to B natural. There will still be 3 flats, B flat, E flat and A flat, in the key signature but now B natural will appear as an accidental on the music staff.
