Altered chords

An altered chord is a chord with diatonic notes replaced by, or altered to, a neighbouring pitch in the chromatic scale (except for the leading note in the harmonic minor). According to the traditional classification, secondary dominants are "borrowed" dominants, taken from another key. Modal interchange means borrowing chords from a mode with the same tonic. The most common are chords borrowed to a parallel major key from a minor key; for example an F minor chord can be borrowed to C major. However, harmonies referring to the church modes are modal; the first inversion of F major in E minor (Neapolitan sixth, N6), which refers to the Phrygian mode.
