Cadences
How musical phrases end · V → I · IV → I · V → vi · ♭II → I
Cadences are how musical phrases come to a stop. They are the punctuation marks of tonal music — some resolve like periods (the Perfect Authentic Cadence), some hang in the air like commas (the Half Cadence), and some set you up for a resolution that never quite comes (the Deceptive Cadence). Mastering five or six of these patterns gives you the vocabulary to end a phrase exactly the way you mean to.

About Cadences
A cadence is the chord progression that ends a musical phrase. In tonal music, cadences function the way punctuation functions in written language — they tell the listener whether a phrase has come to a definitive close, a soft pause, or a surprising swerve. The choice of cadence shapes the emotional arc of a piece: a Perfect Authentic Cadence at the end of a symphony makes the conclusion feel inevitable, while a Deceptive Cadence in a Beethoven sonata can hold the listener in suspense for another sixteen bars.
Western tonal music recognizes a small number of standard cadence patterns, each with a distinct sound and function. The five most important are the Perfect Authentic, Imperfect Authentic, Half, Plagal, and Deceptive cadences. A sixth — the Phrygian Half Cadence — is a specialized variant that shows up specifically in minor keys and gives the music an unmistakable Baroque or Spanish flavor.
Cadences come in two emotional categories. Conclusive cadences land on the tonic (I or i) and create a sense of arrival — the listener feels the phrase has finished. Inconclusive cadences end on something other than the tonic and leave the music feeling open, expectant, or surprised. Mastering cadences means understanding both which chords are involved and what emotional effect each combination produces.
Variations
Half Cadence
Ends on V — a musical comma. Sets up continuation rather than closing the phrase.
Plagal Cadence — the "Amen"
IV → I. Softer than authentic; no leading-tone pull. The traditional hymn ending.
Deceptive Cadence
V fakes the listener out by landing on vi instead of I. Beethoven's favorite phrase-extender.
Phrygian Half Cadence
iv⁶ → V in minor. Stepwise bass descent gives it a Baroque, Spanish flavor.
