A Neapolitan chord is simply a major triad that is built on a special note.
（那不勒斯和絃是一個建立在特殊音上的大三和弦）First, figure out the second scale degree. In C Minor, this is D.
（首先，找到調性的第二個音，C小調中是D）Now build a major triad. This results in D-flat–F–A-flat.
（然後建立一個大三和弦，就是降D-F-降A）A D-flat major chord is the Neapolitan of C Minor.
（降D的大三和弦就是C小調的那不勒斯和絃） |
Next, let's build the Neapolitan of E Minor.
（接下來，我們在E小調下建立一個那不勒斯和絃）Now, build a major triad. This results in F–A–C.
（建立一個大三和弦，就是F-A-C）Thus, an F major chord is the Neapolitan of E Minor.
（所以，F的大三和弦就是E小調的那不勒斯和絃） |Next, let's build the Neapolitan of A-flat Major.
（接下來，我們在降A大調下建立一個那不勒斯和絃）In this key, the second scale degree is B-flat.
（在這個調上，調性的第二個音降B）Now, build a major triad. This results in B-double-flat–D-flat–F-flat.
（建立一個大三和弦，就是倍降B-降D-降F）Thus, a B-double-flat major chord is the Neapolitan of A-flat Major.
（所以，倍降B的大三和弦就是降A大調的那不勒斯和絃） |For our final example, let's build the Neapolitan of A Major.
（最後，我們在A大調下建立一個那不勒斯和絃）Now, build a major triad. This results in B-flat–D–F.
（建立一個大三和弦，就是B-降D-F）Thus, a B-flat major chord is the Neapolitan of A Major.
（所以，降B大三和弦就是A大調的那不勒斯和絃） |
