Dominant Function

Leading Tone: The leading tone is the seventh scale degree that resolves strongly to the tonic. It adds even more tension and urgency to the dominant function.

Cadence: A cadence is a musical phrase or progression that provides closure at the end of a musical phrase or section. The dominant function often plays a crucial role in creating cadences.

Secondary Dominant: A secondary dominant is when a non-diatonic dominant chord is used to create temporary tension and lead to another chord within a key. It adds extra color and excitement to harmonic progressions.
