Chord progressionA chord progression (also chord sequence and harmonic progression), as its name implies, is a series of chord (music)s played in an order. Part and parcel of this action is the idea that the chords relate to each other in some way, whether closely or distantly, and they as a whole become an entity in themselves. Chord progressions are central to most modern European-influenced music and create cyclic or sectional musical forms. Compare to a simultaneity succession. A chord change is a movement from one chord to another and may be thought of as either the most basic chord progression or as a portion of longer chord progressions which involve more than two chords (see shift of level). Generally, successive chords in a chord progression share some notes. This provides harmonic continuity within the progression (see voice leading). The most common chords in Western Classical music and Pop music music are based on the first, fourth, and fifth scale degrees (Tonic (music), subdominant and dominant (music)); see three chord song, eight bar blues, and twelve bar blues. The chord based on the second scale degree is used in the most common chord progression in Jazz, ii-V-I. Chord progressions are usually associated with a scale (music) and the notes of each chord are usually taken from that scale. melody and other parts usually comply with the chord changes in that their notes are usually taken from the chord currently playing. Notes which are not taken from the chord are called nonchord tones and usually resolve quickly to a chord tone. In music of the common practice period generally only certain chord progressions are used and many of the progressions not used are not traditionally tonality. {| border=1 cellpadding=5 cellspacing=0 |+Table of common progressions during the common practice period !colspan=4|Table of Common Progressions |- |I, i |colspan=3|May progress to any other triad.

Important transformations include: *replacement or substitution of a chord by its dominant or subdominant, example: 1 2 3 4 5 6 7 8 9 10 11 12 I/IV/I/I7//IV/VII7/III7/VI7//II7/V7/I/I// *use of chromatic passing chords, example: ...7 8 9... ...III7/bIII7/II7... *and chord alterations such as minor chords, diminished sevenths, etc. Sequences by fourth, rather than fifth, include Jimi Hendrix's "Hey Joe": 1 2 3 4 5 6 7 8 9 10 11 12 bVi, bIII/bVII, IV/I/I//bVI, bIII/bVII, IV/I/I//bVI, bIII/bVII, IV/I/I// These often result in Aeolian harmony and lack perfect cadences (V-I). Middleton (1990, p.198) suggests that both modal and fourth-orientated structures, rather than being "distortions or surface transformations of Schenker's favoured V-I kernel, it is more likely that both are branches of a deeper principle, that of tonic/not-tonic differentiation." The chord sequence of The Beatles' "I Saw Her Standing There" derives from a tree with both subdominant and dominant branches. ==Source== *Middleton, Richard (1990/2002). ''Studying Popular Music''.

Therefore A chord is common to several tonalities :What you listed are scales. They consist of tones, not chords! And of course a certain tone can be present in several different scales, after all there are only 12 tones. ---> Especially modern jazz artists use these "characteristics " of chords by using chords progressions to create a constantly ongoing modulation .... Theorists/ teachers (of this particular mode of playing ) include Nathan Davis Hal Singer ----> Performers of these styles even fabricated so called " synthetic " scales on several ( simple three chord ) progressions ( and a different one on "bridges" in anatole -pieces / ballad and tin -pan -alley material ) Sonny Rollins is an outstanding " player " of these linear approaches to motivistic and rapid scale- changing modes of improvisation ---- see short discussion at Talk:Harmonic progression ---- --- In the table, there under major IV, one of the progressions starts with a VI, I think this is a mistake, all the others start with the same as the title of the row but I don't feel as if I know enough to change it!
