TYPES OF CADENCES
A cadence is a two-chord progression that occurs at the end of a phrase.
Perfect Authentic Cadence ( PAC )
Dominant → Tonic ( V → I )
Root Position Chords
Tonic = highest voice of final chord
Imperfect Authentic Cadence ( IAC )
Root Position IAC: highest voice of final chord is NOT the tonic
Inverted IAC: one or both chords are inverted
Leading Tone IAC: V is replaced with vii diminished chord
Half Cadence ( HC )
Cadence ending on the dominant ( V )
Plagal Cadence ( PC )
Subdominant → Tonic ( IV/iv → I)
Deceptive Cadence ( DC )
The dominant chord (V) resolves to a
chord other than the tonic. In most cases,
this is the submediant chord ( VI/vi)
