In many styles of music, use of the viiº chord from the major key is rare. Other times it moves to the IV chord: C-B♭-F-C How the♭VII Chord Works Often, the ♭VII chord moves back to the I chord: C-B♭-C, or F-B♭-C The ♭VII chord appears in chord progressions in many ways. In the key of C major, a ♭VII chord would be B♭ (B♭-D-F) or B♭7 (B♭-D-F-A♭) borrowed from the parallel minor scale of C minor. And, sometimes, it causes heated debates. It is quite common, but it creates a lot of confusion and is easy to analyze incorrectly. While all of the borrowed chord possibilities do get used (including the i, iiº and v), most often you will encounter the minor iv, ♭III, ♭VI, and ♭VII chords borrowed from the parallel minor key. The last common borrowed chord we will discuss in this lesson block is the ♭VII chord (“flat seven chord”).
