C Harmonic Minor Scale

The C harmonic minor scale contains C – D – Eb – F – G – Ab – B. It is C natural minor with the 7th raised from Bb to B. It keeps the key signature of C minor (3 flats: Bb, Eb and Ab), and the B is written as an accidental.

Right hand, going up: the thumb tucks under to F. Left hand, going up: finger 3 crosses over the thumb to Ab. Practise each hand alone, slowly, until the turns are smooth, then play hands together.

Only the 7th changes. B sits a half step below C, so it pulls up to the tonic, which Bb does not. It also leaves a gap of three semitones between Ab and B, an augmented 2nd, and that gap is the sound people recognise in this scale.

What C harmonic minor is used for

Harmonic minor is what makes a minor key cadence. The raised 7th turns the chord on the 5th degree from minor into major, G (G B D), and that chord resolves firmly to Cm. It also gives the diminished Bdim (B D F) on the 7th degree. Most minor-key classical harmony borrows these chords, even when the melody stays in natural minor.

Step pattern

The harmonic minor scale is built from the pattern W – H – W – W – H – W+H – H (W = whole step, H = half step, W+H = three semitones). Apply that pattern from any starting note and you get the same scale in a different key.

Key signature

C minor has 3 flats: Bb, Eb and Ab, and harmonic minor uses the same key signature with one accidental, on the raised 7th: B. See the key of C minor for the rest of its chords.

What is the difference between C harmonic minor and C natural minor?

Only the 7th note. C natural minor has Bb; C harmonic minor raises it to B, a half step below the tonic.

What key signature does C harmonic minor use?

The key signature of C minor: 3 flats: Bb, Eb and Ab. The raised 7th, B, is written as an accidental.

What is the fingering for the C harmonic minor scale on piano?

What is the step pattern of the harmonic minor scale?

It follows the pattern W – H – W – W – H – W+H – H, where W is a whole step (two semitones), H is a half step (one semitone) and W+H is three semitones.
