→Authentic Cadence
=== Authentic Cadence ===
An ''Authentic Cadence'' is a dominant-tonic progression. The dominant 7th can be used in place of the dominant triad. A ''perfect authentic cadence'' must use the V or V{{7}} chord as the dominant, have both chords in root position, and voice the tonic note in the tonic chord in the highest voice. An ''imperfect authentic cadence'' is similar, but breaks one or more of the above conditions. It may substitute the vii{{dim}} chord for the V.
=== Half Cadence ===
A ''Half Cadence'' is a progression that moves from basically any chord to the V chord, leaving a sense of unresolved tension. The cadence is still designed to indicate the end of a phrase or musical idea, but it begs for continuation, either through a repetition or another idea.
=== Plagal Cadence ===
A ''Plagal Cadence'' is a IV - I progression, also called the "Amen Cadence" because of its frequent use in church hymns. Because there is no leading tone to tonic movement, the cadence does not imply tonality. For instance a I-IV-I progression could also be interpreted as a V-I-V progression. In this way, it is a weak resolution, but a resolution to tonic, nonetheless.
=== Interrupted/Deceptive Cadence ===
A V-vi or V-VI progression, commonly using V{{7}}. Creates a weak or suspended feeling, similar to the half cadence.
