Neapolitan Chord (bII)
The Neapolitan chord is a major triad built on the flattened second degree of a key. It is one of the most dramatic borrowed chords in music, creating a striking dark tension before resolving to the dominant or tonic. Used in classical cadences, jazz reharmonization, flamenco, metal breakdowns, and neo-soul.
What Is the Neapolitan Chord?
The Neapolitan chord is named after the Neapolitan school of opera in 18th-century Naples, where composers used it frequently for dramatic effect. It is a major chord built on the flattened second scale degree (bII) of a key.
In C minor, the 2nd scale degree is D. Flatten it to Db. Build a major triad: Db - F - Ab. That is the Neapolitan chord.
It is typically used in first inversion (N6 or bII6), with F in the bass instead of Db. The first inversion creates smoother voice leading to the V chord (G major in C minor) and is why you will see "N6" in most classical score analysis.
bII vs N6: Root Position vs First Inversion
- Bass note: Db (the flattened root)
- Chord: Db - F - Ab
- Used in: rock, metal, direct shock
- Voice leading: larger bass leap
- Example: Db major chord before Cm in a metal riff
- Bass note: F (the third of the chord)
- Chord: F - Ab - Db (first inversion of Db major)
- Used in: classical cadences, jazz, film
- Voice leading: smooth half-step to E in V chord
- Example: bII6 - V - i in a classical cadence
How to Build the Neapolitan Chord
Four steps to find the Neapolitan chord in any key:
- Identify your key (use BeatKey to detect the key of your sample)
- Find the 2nd scale degree (the note one whole step above the tonic)
- Flatten it by one half step (lower by one semitone)
- Build a major triad on that flattened note
Neapolitan Chord in All 12 Keys
The Neapolitan chord works in both major and minor keys. It is more common in minor (where the bII is more dissonant from the tonic), but is used in major keys in jazz, classical, and film scoring.

Why the Neapolitan Chord Works
The flattened root (Db in C minor) is outside the diatonic scale. It hits the ear as unexpected color, creating a dramatic shift in tone, especially when moving from a minor tonic chord.
In N6 (first inversion), the bass note F is one half step above E, the third of the V chord (G major). This semitone voice leading creates an almost gravitational pull toward the dominant.
The Neapolitan functions like a subdominant (IV) chord. It moves away from the tonic toward the dominant, building tension before the final resolution to i or I. It can replace or precede IV in a cadence.
Neapolitan Chord Progressions
The most classic usage. The N6 replaces the pre-dominant iv or ii(dim) chord, creating a more colorful and dramatic preparation for the final V-i cadence. The F bass note in N6 slides down to E in the G chord.
Skip the dominant entirely. The bII chord creates a sudden chromatic shock and immediately returns home. Common in metal riffs, flamenco, and dramatic film cues. Beethoven uses this pattern in the Moonlight Sonata.
In jazz, the Neapolitan often appears as a major 7th chord (bIImaj7) substituting for the ii chord before the tonic. The chromatic bass line D - Db - C creates a smooth descending approach. Also works as a tritone substitution of the V chord.
The full classical pre-dominant approach. The iv chord leads into N6 which then resolves to V7 before the tonic. Each chord adds more tension before the final release. Common in Baroque and Classical era concerto cadences.
A modern neo-soul pattern where the Neapolitan major 7th chord provides a lush, dreamy color before returning to the minor tonic. The whole-step bass movement (D - Eb - D) creates a gentle rocking tension. Used frequently by neo-soul and hip-hop producers for melodic minor color.
The Neapolitan Chord by Genre
| Genre | How It Is Used | Common Pattern | Famous Example |
|---|---|---|---|
| Classical / Baroque | Pre-dominant cadence, N6 before V7-i | i - N6 - V7 - i | Beethoven Moonlight Sonata (1st mvt) |
| Jazz | bIImaj7 as chord substitution, chromatic bass approach | Dm7 - Dbmaj7 - Cmaj7 | Bill Evans, Coltrane reharmonizations |
| Metal / Prog | bII in root position for shock effect, power chord riffs | i - bII - i | Metallica, Dream Theater breakdowns |
| Flamenco | Phrygian cadence with bII, Andalusian descending bass | Am - G - F - E | Traditional flamenco cante jondo |
| Film Score | N6 for menace, tension before reveal | i - N6 - V - i | Hans Zimmer, John Williams tension cues |
| Neo-Soul / R&B | bIImaj7 as a lush color chord, modal interchange | i7 - bIImaj7 - i7 vamp | D'Angelo, Robert Glasper progressions |
| Hip-Hop | Sampled from jazz and neo-soul, filtered for lo-fi color | Dm7 - Ebmaj7 loop | J Dilla influenced beats |
Famous Neapolitan Chord Examples
The first movement (Adagio sostenuto) in C# minor opens with a famous passage that visits the Neapolitan chord (D major, bII of C# minor). The D major chord creates an otherworldly brightness against the dark C# minor tonic.
The C minor prelude ends with an unmistakable Neapolitan cadence. The bII chord (Db major) over F in the bass (N6) creates overwhelming tension before the final V7-i resolution. One of the most analyzed Neapolitan uses in piano literature.
The verse progression uses a bII (F major, the Neapolitan of E minor) as part of its chromatic descent, giving the song its unsettled, melancholic feel.
The clean middle section uses an E Phrygian/Neapolitan cadence (F major to E, or bII-i) which is central to the classical and metal crossover sound. The F to E half-step bass movement is quintessentially Neapolitan.
Evans uses bIImaj7 substitutions throughout his modal jazz work to create chromatic color shifts without fully leaving the tonic key center. The Neapolitan appears as a temporary tonal escape.
The Lacrimosa in D minor contains several Neapolitan chord appearances as part of the sustained emotional weight. The Eb major chord (bII of D minor) contributes to the weeping, sorrowful harmonic palette.
Using the Neapolitan Chord in Your DAW
Upload your sample to BeatKey to confirm the key. Then find the bII chord: flatten the 2nd scale degree and build a major triad on it. For A minor, the 2nd degree is B, flattened to Bb, giving you Bb - D - F.
Place N6 (first inversion) in your Piano Roll with the third of the bII chord in the bass. In A minor, that is D in the bass for Bb major (N6). This gives you a smooth D - C# bass line into the E (V) chord.
Instead of a plain bII major triad, use bIImaj7 for a richer, jazzier color. In C minor, that is Dbmaj7 (Db - F - Ab - C). Voicing the 7th on top creates the lush sound common in neo-soul progressions.
The Neapolitan works best as a pre-dominant chord. Use the pattern bII6 - V - i or bII - V - i. The bass moving from bII (or the 3rd of N6) to the dominant root creates strong momentum toward the final resolution.
In metal and rock, skip the V chord entirely. Alternate bII - i repeatedly for a stomping, Phrygian-flavored riff. The root position bII chord (not inverted) gives maximum impact with the flatted root in the bass.
When moving from N6 to V, hold or resolve inner voices smoothly. The Db in Db/F resolves up to D in G major (V). The Ab resolves to G. The F (bass) resolves down to E. Map these in your Piano Roll for a complete classical cadence.

Neapolitan Chord FAQ
What is a Neapolitan chord?
A Neapolitan chord is a major chord built on the flattened second scale degree (bII) of a key. In C minor, the Neapolitan is Db major. It is most often played in first inversion (N6 or bII6) with the third in the bass, creating strong tension that resolves toward the dominant (V) chord and then the tonic. It is common in classical music, jazz, flamenco, and metal.
How do you build a Neapolitan chord?
Find the 2nd scale degree in your key, flatten it by one half step, and build a major triad on that note. In C minor: 2nd degree is D, flatten to Db, build Db - F - Ab. In A minor: 2nd degree is B, flatten to Bb, build Bb - D - F. For first inversion (N6), put the third of the chord in the bass: F - Ab - Db in C minor, or D - F - Bb in A minor.
What is the difference between bII and N6?
bII is the Neapolitan chord in root position (the flattened root is in the bass). N6 is the Neapolitan chord in first inversion (the third is in the bass). In C minor: bII = Db - F - Ab, N6 = F - Ab - Db. The first inversion (N6) is far more common in classical and jazz writing because the bass note creates a smoother half-step voice leading to the dominant chord.
How do you use the Neapolitan chord in a DAW?
Use BeatKey to detect your key. Find the bII chord by flattening the 2nd scale degree and building a major triad. In your Piano Roll, place the Neapolitan before the V chord (bII6 - V - i is the classic pattern) or directly before the tonic (bII - i) for a metal/shock effect. For jazz, try bIImaj7 as a substitute for the ii chord in a ii - V - I progression, giving you the smooth D - Db - C chromatic bass line.
