Bridge

In fugal exposition, a short passage linking the end of the answer with the next entry of the subject, often serving to modulate from the dominant back to the tonic; Also, in popular music, a short section, usually in a different tonality, that seperates the initial statement of the main melody and its return

Cadence

A modulation involving no common chords, in which a diatonic pitch moves to a chromatically altered pitch in one or more voices

Chromatic Pivot

The pivotal chord in a chromatic modulation. It usually serves a recognizable function in both keys. However, its function in at least one of the keys is chromatic, and in this way it differs from a common chord, which functions diatonically in both keys.
