A Neapolitan chord is simply a major triad that is built on a special note.
（那不勒斯和弦是一个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，找到调性的第二个音，C小调中是D）Now build a major triad. This results in D-flat–F–A-flat.
（然后建立一个大三和弦，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小调的那不勒斯和弦） |
Next, let's build the Neapolitan of E Minor.
（接下来，我们在E小调下建立一个那不勒斯和弦）Now, build a major triad. This results in F–A–C.
（建立一个大三和弦，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小调的那不勒斯和弦） |Next, let's build the Neapolitan of A-flat Major.
（接下来，我们在降A大调下建立一个那不勒斯和弦）In this key, the second scale degree is B-flat.
（在这个调上，调性的第二个音降B）Now, build a major triad. This results in B-double-flat–D-flat–F-flat.
（建立一个大三和弦，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大调的那不勒斯和弦） |For our final example, let's build the Neapolitan of A Major.
（最后，我们在A大调下建立一个那不勒斯和弦）Now, build a major triad. This results in B-flat–D–F.
（建立一个大三和弦，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大调的那不勒斯和弦） |
