A chord progression (or harmonic progression) is a series of musical chord
Chord (music)
In music and music theory a chord is a set of three or more different notes from a specific key that sound simultaneously.

In music, the subdominant is the technical name for the fourth tonal degree of the diatonic scale. It is so called because it is the same distance "below" the tonic as the dominant is above the tonic - in other words, the tonic is the dominant of the subdominant. It is also the note immediately...

Although all this allows for a large number of possible progressions (depending upon the length of the progression), in practice progressions are often limited to a few bars' length and certain progressions are favoured above others: there is a certain amount of fashion in this and a chord progression may even define an entire genre.

In western classical notation chords built on the scale are numbered with Roman numerals. A D chord will be figured I in the key of D, for example, but IV in the key of A. Minor chords are signified by lower case Roman, so that D minor in the key of C would be written ii. Other forms of chord notation

, consist of "adjacent roots in ascending fourth or descending fifth relationship,"—for instance, the sequence VI - ii - V - I ascends to the fourth note above each time (returning to I after VII). Such a motion, based upon close harmonic relations, offers "undoubtedly the most common and the strongest of all harmonic progressions". The succession of cadences gives an impression of inevitable return to the key-note of the piece.

Short cyclical progressions may be derived by selecting a sequence of chords from the series completing a circle from the tonic through all seven diatonic chords:
  • I - IV - viio - iii - vi - ii - V - I (in major)
  • I - V - I
  • I - IV - V - I


This felicitous type of progression was much used by classical composers, who introduced increasingly subtle inflections. Particularly, substitution of major for minor chords giving, for example, I - VI - II - V allowed a more sophisticated chromaticism
