Cadences: Musical Punctuation
Harmonic formulas that mark phrase endings and structural boundaries—from the conclusive Authentic cadence (V-I, the 'period' of music) to the questioning Half cadence (ends on V, like a 'comma'), gentle Plagal (IV-I, the 'Amen' ending), and surprising Deceptive cadence (V-vi, the 'plot twist')—cadences create formal articulation, manage listener expectation, and provide the grammatical punctuation that makes musical phrases intelligible.

I. Conceptual Positioning
🎯Problem Solved
How music creates clear phrase boundaries and formal structure—cadences are the harmonic 'punctuation marks' that tell listeners when phrases end, whether endings are conclusive or continuational, where to breathe mentally, and how formal sections articulate, transforming continuous sound into comprehensible musical sentences and paragraphs.
🔨Skills Built
- •Identify all four cadence types by ear and score
- •Understand cadential strength (authentic > plagal > deceptive > half)
- •Apply cadences to create phrase structure
- •Use cadences for formal articulation (periods, sentences)
- •Recognize cadential expectations and violations
- •Compose phrases with appropriate cadential endings
