imperfetto

Imperfect cadences sound unfinished. They sound as though they want to carry on to complete the music properly. An imperfect cadence ends on chord V. Plagal cadences sound finished.

An easy way to remember the imperfect cadence is that it is the opposite to a perfect cadence. An interrupted cadence begins as a perfect cadnece with chord V, however finishes on a minor chord giving the impression of an 'interrupted' perfect cadence, which makes the music sound surprising.

A cadence is formed by two chords at the end of a phrase. An interrupted cadence is usually formed by the chords V–VI. (In the key of C major, chords G to A minor.) This creates an ending which can sound unfinished – where the listener is surprised that the music has drawn to a close. Interrupted cadence in C major.

The perfect cadence is also known as the authentic cadence. It is a progression from chord V to chord I. For example, in C major the progression would be from a G chord to a C chord. The plagal cadence is from chord IV to chord I - in C major this would be an F chord followed by a C chord.

This because there are four different kinds of cadences:

• Authentic Cadence.
• Half Cadence.
• Plagal Cadence.
• Deceptive Cadence.

In a perfect authentic cadence (PAC), the chords are in root position – that is, the roots of both chords are in the bass – and the tonic is in the highest voice of the final chord. This is generally considered the strongest type of cadence and often found at structurally defining moments.

the perfect cadence In the strongest type of authentic cadence, called the perfect cadence, the upper voice proceeds stepwise either upward from the leading tone (seventh degree of the scale) or downward from the second degree to the tonic note, while the lowest voice skips from the dominant note upward a fourth or downward a fifth to the ...

In Western musical theory, a cadence (Latin cadentia, "a falling") is the end of a phrase in which the melody or harmony creates a sense of full or partial resolution, especially in music of the 16th century onwards.

Interrupted Cadence or Deceptive Cadence The most common chord progression you will come across is from chord V to chord VI (V-VI). So, in this example of an interrupted cadence in C major below, the last 2 chords are V (G) and VI (A minor). The music very much sounds as though it has been “interrupted”.

plagal. / (ˈpleɪɡəl) / adjective. (of a cadence) progressing from the subdominant to the tonic chord, as in the Amen of a hymn. (of a mode) commencing upon the dominant of an authentic mode, but sharing the same final as the authentic mode.

Plagal Cadences are at the ends of phrases and are usually either IV -> I(As I've seen occasionally in Bach chorales) or I -> IV64 -> IV64 -> I(As in Handel's Hallelujah Chorus) whereas the Plagal Tag is towards the beginning or middle of a phrase and always starts and ends with the tonic chord, but can have any ...
