In music there are standard cadence types. The traditional way of learning about cadences was to use numbered chords, mostly triads, in example keys.
First I will use the triads of C major and give out the modern chord names for them.

1) Perfect cadence or Full close
V - I
G major followed By C major.
This cadence is generally thought of as the full
stop. It it the final ending. And very definite sounding.
2) Plagal Cadence
IV - I
F major followed by C major
This one is also a full stop, but a more playful
one.
3) Imperfect Cadence or Half Close
I - V C major followed by G major
or IV - V F major followed by G major
These cadences point to the end of the phrase, but suggest that there's more to come.
4) Interrupted Cadence or abrupt cadence
V - VI
G major followed by A minor
Leaving a surprise, the listener hears the music
coming to an end and expects to hear a tonic, but another chord is there
instead.
5) Phrygian Cadence ( a )
A cadence which starts fron the Major Key, and ends with a chord on the dominant of the relative minor key.
6) Phrygian Cadence ( b )
Any sort of imperfect cadence in a minor mode
7) Phrygian Cadence ( c )
The first inversion of IV followed by I
A G
C - B
F D
