cadencial

Cadencial is an adjective used primarily in music theory to describe anything pertaining to cadence, the momentary musical punctuation that closes a phrase, section, or piece. The term is used in Romance-language music literature; in English the corresponding term is cadential. Cadencial phenomena include the harmonic progressions, melodic gestures, and rhythmic patterns that create a sense of closure.

Cadences function by establishing or reinforcing tonal center. They may vary in how they sound and how they are prepared, but most cadential formulas rely on a predominant to dominant movement toward the tonic. The effect is a sense of resolution or pause that marks the end of a musical unit.

Common cadential types include: authentic cadence (V–I), often with root-position I; half cadence (ending on V); plagal cadence (IV–I); and deceptive cadence (V–VI). The classical period features a specialized cadential six-four, a I6/4 that functions as a predominant before V and resolves to V (and then often to I).

Historically, cadential practice is central to Western tonal music from the Common Practice period onward and remains a fundamental concept in music theory, analysis, and pedagogy. Beyond Western music, cadence-like closures appear in various traditions, though the exact cadential formulas differ.
