C Neapolitan major Scale
C Neapolitan major contains 7 notes: C, D♭, E♭, F, G, A, B. It has 2 flats: D♭, E♭. The step pattern is H–W–W–W–W–W–H.
A majestic, dramatic scale beloved by 19th-century Italian opera composers. Despite the "major" in its name, it actually starts dark (with a b2 and b3) before unfolding into brightness — a dramatic arc packed into a single octave.
The formula is 1, b2, b3, 4, 5, 6, 7. It combines Phrygian's dark opening (b2, b3) with major's bright upper structure (5, 6, 7). The "Neapolitan" chord (bII major) — one of the most powerful chords in classical harmony — is generated naturally by this scale. It resembles melodic minor but with a b2 instead of a natural 2nd.
The dramatic shift from dark lower notes to bright upper notes creates natural phrasing arcs on the fretboard. It harmonizes well over min(maj7) chords, and in jazz contexts the altered notes can be adapted for dominant 7th #5 or #11 voicings by shifting the root focus. Try it for operatic, sweeping melodic lines.
