Tonal Areas

“Tonicization” is the treatment of a non-tonic chord if it were, temporarily, the tonic.  There are degrees of tonicization, ranging from less substantial to more substantial ones.  On the continuum shown below, a secondary dominant is a less substantive tonicization, as it involves just a dominant chord and its resolution.  Modulation is more substantial, as it indicates a change of tonic, usually with a cadence in the new key.  In between these two extremes is a “tonal area,” a tonicization that involves several chords, usually a pre-dominant–dominant–tonic progression in the new key, but with no cadence in it.
