The circle progression is commonly a succession through all seven
diatonic chords of a
diatonic scale by fifths, including one progression by
diminished fifth, (in C: between F and B) and one
diminished chord (in C major, B), returning to the
tonic at the end. A full circle of fifths progression in C major is shown below. {{block indent| { \new PianoStaff > \new Staff > >> } }} Shorter progressions may be derived from this by selecting certain specific chords from the progression through all seven diatonic chords. The
ii–V–I turnaround lies at the end of the circle progression, as does the vi–ii–V–I progression of root movement by descending fifths, which establishes tonality and also strengthens the
key through the contrast of
minor and major. In a minor key, the progression is
i–iv–VII–III–VI–ii°–V–i. ==See also==
