Cadences are divided into four main types, according to their harmonic progression: authentic (typically perfect authentic or imperfect authentic), half, plagal, and deceptive. Typically, phrases end on authentic or half cadences, and the terms plagal and deceptive refer to motion that avoids or follows a phrase-ending cadence.
Diagram of a typical period consisting of two phrases [5] [6] [7]. In Western art music or Classical music, a period is a group of phrases consisting usually of at least one antecedent phrase and one consequent phrase totaling about 8 bars in length (though this varies depending on meter and tempo).
The analysis of a plagal cadence as an extension of an authentic cadence probably stems from the work of Heinrich Schenker, and certainly applies primarily to music such as Mozart and Beethoven. It's easy enough to find genuine plagal cadences in Brahms and other late Romantics (not to mention earlier composers such as Schütz and Monteverdi).
In music, I–IV–V–I or IV–V–I is a chord progression and cadence that, "unequivocally defines the point of origin and the total system, the key." [1] Composers often begin pieces with this progression as an exposition of the tonality: [1]
This is an example of a suspended chord. In reference to chords and progressions for example, a phrase ending with the following cadence IV–V, a half cadence, does not have a high degree of resolution. However, if this cadence were changed to (IV–)V–I, an authentic cadence, it would resolve much more strongly by ending on the tonic I chord.
Backdoor compared with the dominant (front door) in the chromatic circle: they share two tones and are transpositionally equivalent. In jazz and jazz harmony, the chord progression from iv 7 to ♭ VII 7 to I (the tonic or "home" chord) has been nicknamed the backdoor progression [1] [2] or the backdoor ii-V, as described by jazz theorist and author Jerry Coker.
This particular cadence, V–I, is known as an authentic cadence. However, since a I–V–I progression is repetitive and skips most of the circle of fifths, it is common practice to precede the dominant chord with a suitable predominant chord, such as a IV chord or a ii chord (in major ), in order to maintain interest.
According to Andranik Tangian, [7] analytical phrasing can be quite subjective, the only point is that it should follow a certain logic. For example, Webern’s Klangfarbenmelodie-styled orchestral arrangement of Ricercar from Bach’s Musical offering demonstrates Webern’s analytical phrasing of the theme, which is quite subjective on the one hand but, on the other hand, logically consistent:
