C Harmonic Minor Scale: Notes, Chords, and How to Play It

By Interactive Chord Finder ·

The C harmonic minor scale is a natural starting point for learning harmonic minor on piano, as its parallel major (C major) has no sharps or flats. It differs from C natural minor by a single note — the seventh degree is raised from B♭ to B — creating the leading tone and the distinctive augmented second between A♭ and B that define the harmonic minor sound.

Notes of the C Harmonic Minor Scale

The C harmonic minor scale contains seven notes:

C – D – E♭ – F – G – A♭ – B

It follows the harmonic minor interval pattern — W–H–W–W–H–3H–H — where 3H represents the augmented second (three half steps) between the sixth and seventh degrees (A♭ to B).

Compared to C natural minor (C–D–E♭–F–G–A♭–B♭), only B♭ changes to B. This raises the seventh from a minor 7th to a major 7th, restoring the leading tone that pulls strongly toward C.

The augmented second between A♭ and B is the scale’s most distinctive interval — a flat note leaping to a natural note across three half steps.

For a broader look at the three minor scale types, see Minor Scales: Natural, Harmonic, and Melodic.

C Harmonic Minor on Piano

On the piano, C harmonic minor uses three flats (E♭, A♭) from the natural minor key signature, but the seventh degree returns to the white key B. This creates a distinctive hand shape: mostly white keys with two black-key detours.

Right hand fingering (ascending): 1 – 2 – 3 – 1 – 2 – 3 – 4 – 5 (thumb crosses under after E♭, then fingers walk up to C)

Left hand fingering (ascending): 5 – 4 – 3 – 2 – 1 – 3 – 2 – 1 (after the thumb plays G, the third finger crosses over to A♭)

The augmented second from A♭ (black) to B (white) spans three half steps. This stretch feels wider than the surrounding intervals and requires deliberate practice.

C Harmonic Minor on Guitar

On guitar, C harmonic minor is commonly played starting at the 8th fret of the 6th string or the 3rd fret of the 5th string.

Position at 3rd fret (5th string root):

StringFretNote
5th (A)3C
5th (A)5D
5th (A)6E♭
4th (D)3F
4th (D)5G
4th (D)6A♭
3rd (G)4B
3rd (G)5C

The augmented second from A♭ to B spans four frets on a single string — the physical hallmark of harmonic minor on the guitar.

Key features:

  1. The V chord is major (G major, not G minor). The raised B turns the v chord into V, creating the strong G–Cm cadence that defines classical harmony in C minor.

  2. The III chord is augmented (E♭aug), the characteristic harmonic minor colour chord.

The V7 (G7) is the same dominant seventh chord that resolves to C major — but here it resolves to C minor, giving the cadence a darker, more dramatic quality. For more on seventh chords, see Seventh Chords: The Complete Guide.

Common Chord Progressions in C Harmonic Minor

i – iv – V – iCm – Fm – G – CmClassic minor cadence

i – iv – V7 – iCm – Fm – G7 – CmClassical/jazz minor

The V–i cadence (G–Cm) is the harmonic engine. The G7–Cm resolution is one of the most satisfying cadences in music, combining the dominant seventh’s tension with the minor tonic’s darkness.

Music That Uses C Harmonic Minor

C harmonic minor appears in works that demand emotional intensity:

  • Beethoven’s Piano Sonata No. 8 (“Pathétique”) – C minor with harmonic minor cadences throughout
  • Beethoven’s Symphony No. 5 – the famous four-note motif in C minor
  • Chopin’s Etude Op. 10, No. 12 (“Revolutionary”) – C minor virtuosity
  • Bach’s Passacaglia and Fugue in C minor – a monumental organ work
  • “O Fortuna” from Carmina Burana – Carl Orff (D minor, but the same cadential feel)
  • Film scores – C harmonic minor suits dark, suspenseful atmospheres

Relationship to Other Minor Scales

ScaleNotesDifference
C natural minorC – D – E♭ – F – G – A♭ – B♭♭7 (no leading tone)
C harmonic minorC – D – E♭ – F – G – A♭ – BRaised 7 (leading tone, aug. 2nd)
C melodic minorC – D – E♭ – F – G – A – BRaised 6 and 7 (smooth, no aug. 2nd)

The natural minor has B♭ as the seventh degree, which lacks the leading-tone pull. Harmonic minor raises it to B, restoring the strong resolution but creating the augmented second (A♭ to B). Melodic minor raises both A♭ to A and B♭ to B, eliminating the augmented second entirely.

Practice Tips

Start from C natural minor. Raise B♭ to B and you have harmonic minor — one note transforms the entire scale.

Isolate the augmented second. Practise A♭ to B until the interval is smooth. On piano, it is a black key to the white key two notes to the right.

Practise the V–i cadence. Play G major to C minor, then G7 to Cm. Notice how this is the same G7 chord that resolves to C major — but the minor resolution adds a darker emotional quality.

Compare with C major. C major and C harmonic minor share two notes in common (C and D) but differ on five. Playing them back to back highlights how the flattened 3rd, 6th, and the augmented second reshape the entire mood.

Use a metronome. Start at 60 BPM and increase only when the augmented second is clean and the rhythm is steady.
