Cadence, authentic or perfect

To be considered a perfect authentic cadence (PAC), the cadence must meet three requirements. First, V must be used rather than vii o. Second, both chords must be in root position. Finally, the highest note of the I (or i) chord must be the tonic of the scale.

cadence, in music, the ending of a phrase, perceived as a rhythmic or melodic articulation or a harmonic change or all of these; in a larger sense, a cadence may be a demarcation of a half-phrase, of a section of music, or of an entire movement.

Perfect cadences are the equivalent of a musical full stop. They feel like the music has come to an end as it resolves to the tonic. In the key of A major, this would be an E major chord (V) followed by A major chord (I).

Authentic cadences involve the progression V–I. They are perfect when both harmonies are in root position and do (^1) is in the soprano over tonic. If either of these conditions is not met, the authentic cadence is imperfect. Half cadences involve the progression x–V, where x is any of a variety of harmonies.

The perfect cadence (also known as the authentic cadence) moves from chord V to chord I (this is written V-I). It is the cadence that sounds the “most finished”. Here is an example of a perfect cadence in C major. Notice how the chords at the end of the phrase go from V (G) – I (C) and it sounds finished.

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 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.

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.

Perfect harmony or an "ideal just scale," which has no exact solution, would require the division of an octave into 12 notes, each of which would be used to create six other consonant intervals.

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.

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.

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.
