Can you explain how dominant chords with upper structures are used in progressions, esp. 2-5-1? What are the implications for good voice leading? And, what major and minor chord voicing a should be used with these? Thanks, Dave Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
