What Is the Neapolitan Sixth?
The Neapolitan Sixth, often abbreviated as N6, is a major chord built on the lowered second degree of the scale. In the key of C major, it consists of the notes D♭-F–A♭.

Its dramatic and expressive qualities made it ideal for moments of tension and release. In jazz and modern music, it has been adapted for various harmonic contexts, often serving as a colorful passing or neighbor chord.

Applying the Neapolitan Sixth in Your Compositions
To effectively incorporate the Neapolitan Sixth, consider the following approaches:
- Use it as a dramatic pivot: Place it before a V or V7 chord to heighten tension.
- Experiment with inversions: While the first inversion is most common, try root position or other inversions for varied color.
- Combine with chromaticism: Use chromatic passing tones around the chord to smooth its transition into or out of other harmonies.
