Neapolitan scale

In music, the major Neapolitan scale and the minor Neapolitan scale are two musical scales. Both scales are minor, in that they both contain a minor third above the root. The major and minor Neapolitan scales are instead differentiated by the quality of their sixth.

The scales are distinguished from the harmonic and ascending melodic minor scales by the lowered supertonic or second scale degree. This could also be known as the "Phrygian harmonic minor" or "Phrygian melodic minor." The scale therefore shares with the Phrygian mode the property of having a minor second above the tonic.

Both are accompanied well by power or minor chords.^[1]

The 4th mode of the Neapolitan major, also known as the Lydian Dominant ♭6 scale, is an excellent choice for the 9 ♯11 ♭13 chord. Said mode contains all the alterations plus the ♮5. A whole tone scale is often used but that mode tends to be minus the ♮5 that the Lydian Minor contains.

The 5th mode of the Neapolitan major is also known as the major Locrian scale.

Notes :

• * While this triad consisted of 1, ♭4 (~3), and ♭5 notes, this is not really a normal triad since no use of 3rd-grade notes (in B : D or D♯/E♭). Instead, this triad more likely shaped as sus♭4 triad (although ♭4 is enharmonic to 3).
• ** 7 enharmonic to 6, so the 6th chords is available instead of 7th (thus being used here).
• *** These chords can actually be respelled as 7alt (the 7♭5 is one of the altered dominant chords).
