Neapolitan scale
In music, the major Neapolitan scale and the minor Neapolitan scale are two musical scales. Both scales are minor, despite their names.
The sequence of scale steps for the Neapolitan minor is as follows:
And for the Neapolitan major:
The scales are distinguished from the harmonic and ascending melodic minor scales by the lowered supertonic or second scale degree.
Both are accompanied well by power or minor chords.
The neapolitan major scale is an excellent choice for the 9#11/b13 (no 5) chord. In the case of the C neapolitan major listed the choice would be F9#11/b13(no 5). This scale contains all the alterations and the perfect 5th. A whole tone scale is often used but it lacks the perfect 5th that the neapolitan major contains.
The 5th mode of the Neapolitan major is also known as the major Locrian scale.
