What is a decorated perfect cadence?

A decorated perfect cadence is a harmonic progression that concludes a musical phrase, typically moving from the dominant (V) chord to the tonic (I) chord, while incorporating additional embellishments or alterations. These decorations can include added tones, suspensions, or arpeggiOS that enhance the resolution and emotional impact of the cadence. While it serves the fundamental function of signaling the end of a musical section, the decorations add complexity and interest to the sound.
