Cadences are the punctuation marks of music. Just as a period ends a sentence and a comma creates a pause, cadences shape how we perceive musical phrases \u2014 creating feelings of closure, suspense, surprise, or continuation. Understanding cadences is essential for analyzing music, composing, and improvising convincingly.
Every cadence is fundamentally about harmonic motion: the relationship between the second-to-last chord and the final chord of a phrase. The specific chords involved, and how they are voiced, determine the cadence type and its emotional effect.
Phrase Structure Insight
Most classical phrases follow an antecedent-consequent pattern: the antecedent phrase ends with a half cadence (on V, creating tension), and the consequent phrase answers with an authentic cadence (V\u2192I, providing resolution). This question-and-answer pattern is the foundation of musical form.
Complete finality, like arriving home
The strongest possible resolution in tonal music. The dominant chord (V) resolves to the tonic (I) with the root of I in the highest voice. This is the musical equivalent of a full stop — a period at the end of a sentence. It provides complete, satisfying closure.
Partial closure, like a soft landing
Same chord motion as the PAC (V to I), but with the 3rd or 5th in the soprano instead of the root. The result is a slightly weaker sense of closure — it resolves, but doesn't feel as final. Often used mid-phrase or to set up a stronger PAC later.
Suspended, questioning — like a comma
Any cadence that ends on the dominant chord (V). It feels unresolved, like a comma or a question mark. The music pauses but clearly needs to continue. Half cadences typically end the first half of a musical phrase (the antecedent), creating expectation for the answering phrase.
Gentle, warm resolution — "Amen"
The subdominant (IV) resolves gently to the tonic (I). Known as the "Amen" cadence because it has been used for centuries to end hymns. It provides closure, but without the strong pull of the leading tone found in V→I. The resolution is warm and gentle rather than dramatic.
Surprise! Expectation subverted
The ear expects V to resolve to I, but instead it lands on vi (the relative minor). This is the musical plot twist. The leading tone still resolves upward, but the bass drops to the 6th scale degree instead of the root. Composers use this to extend phrases, create surprise, or delay the final resolution.
Grand, prepared, ceremonial resolution
The classic approach to a final cadence in common-practice music. A second-inversion tonic chord (I⁶⁴) acts as a decoration of the dominant, creating a double suspension that resolves to V, which then resolves to I. This three-chord pattern is the backbone of classical phrase endings.
In tonal music, phrases are grouped into pairs. The first phrase (the antecedent) asks a question by ending with a weaker cadence \u2014 usually a half cadence. The second phrase (the consequent) provides the answer with a strong authentic cadence.
This pattern appears in thousands of pieces \u2014 from Mozart sonatas to pop songs. The first phrase creates tension by refusing to resolve; the second phrase satisfies the ear by landing firmly on the tonic.
| Cadence | Motion | Feeling | Analogy |
|---|---|---|---|
| Perfect Authentic | V \u2192 I (root in soprano) | Complete finality | Period (full stop) |
| Imperfect Authentic | V \u2192 I (3rd/5th in soprano) | Softer closure | Period (softer voice) |
| Half Cadence | \u2026 \u2192 V | Unresolved tension | Comma, question mark |
| Plagal | IV \u2192 I | Gentle warmth | Peaceful sigh |
| Deceptive | V \u2192 vi | Surprise twist | Plot twist, ellipsis\u2026 |
| Cadential 6/4 | I\u2076\u2074 \u2192 V \u2192 I | Grand, prepared | Drum roll before announcement |
