Cadences are like punctuation marks in music. They are sequences of chords that conclude a phrase, section, or an entire piece. Understanding cadences is key to analyzing how music flows and creates feelings of rest, tension, or surprise.
A cadence is a harmonic progression, typically of two chords, that marks the end of a musical phrase or section. It provides a sense of closure or pause, similar to how commas, periods, or question marks function in written language.
Cadences are fundamental to establishing tonality and guiding the listener's expectations.

Lesson Summary
- Cadences are harmonic progressions marking the end of phrases or sections.
- Perfect Cadence (V-I or V-i): Strongest, final-sounding.
- Plagal Cadence (IV-I or IV-i): "Amen" cadence, softer finality.
- Imperfect Cadence (ending on V): Sounds unfinished, creates expectation.
- Interrupted Cadence (V-VI or V-vi): Surprising, avoids expected resolution.
- Understanding cadences helps in analyzing musical structure and expression.
