How does a perfect authentic cadence differ from an imperfect authentic cadence?
Most people will hear an imperfect cadence as sounding incomplete. Hence, composers usually follow them with a phrase ending in a perfect cadence. An authentic cadence occurs whenever a phrase ends with V or vii o going to I (or i if minor).
Are cadences the same in minor keys?
Minor key cadences are essentially the same as those in a major key.
Can a perfect authentic cadence be in a minor key?
Yes. It is possible to have a perfect cadence in a minor key. The final chord needn’t be major: in the key of a minor, the chords E major followed by a minor are a V-i cadence, which is a perfect cadence.
What is a perfect cadence in a minor key?
In a minor key the V or V7 chord is major (due to the raised 7th note) and the I chord is minor. Along the way the piece may wander off into another key (usually the dominant or subdominant key) but we expect it to return to the tonic key, which is what the perfect cadence does.
What are authentic cadences?
definition. In cadence. In an authentic cadence, a chord that incorporates the dominant triad (based on the fifth tone of the scale) is followed by the tonic triad (based on the first tone of the scale), V–I; the tonic harmony comes at the end of the phrase.
