What is a cadence in music?

A cadence in music specifically refers to a sequence of chords that provides a sense of resolution or pause, usually occurring at the end of a musical phrase. These sequences help to establish the tonal center and often signal the conclusion of a musical idea. Cadences are crucial for creating a sense of closure or transition within a piece, and they can come in various forms, such as perfect, plagal, and deceptive cadences, each serving a distinct musical purpose.

The other options do not accurately define a cadence. While rhythm is undeniably essential in music, referring to a type of rhythm does not capture the specific function of a cadence. Similarly, techniques for improving vocal performance and forms of musical notation pertain to different aspects of music, entirely separate from the chordal structure that a cadence represents. Understanding cadences enriches one's comprehension of musical phrases and their function within compositions.
