=== Neapolitan Chord ===
A ''Neapolitan Chord'' is a major chord using the supertonic m2 of the scale as its root ({{f}}II). It is typically voiced in first inversion, creating a 6th interval between the bass note (3rd) and high note (root) in its triad formulation. Thus, it is often called the Neapolitan 6th, notated as {{f}}II{{6}} or N{{6}}. Harmonically, it functions as a sub-dominant and can be substituted for ii or IV (or iv in a minor key). In C Major, D{{b}} is the Neapolitan chord. In first inversion, it is spelled (F A{{f}} D{{f}}). F is (F A C). Thus, the Neapolitan 6th features the same notes as the IV chord, but the 3rd (A) is lowered a half step, while the 5th (C) is raised a half-step. In C Minor, the iv chord is (F A{{f}} C), differing from the N{{6}} by just 1 half step and lies similarly close to the ii{{dim}} chord (D F A{{f}}), another sub-dominant functioning chord.
