Hello, my friends That's great this site is on again.:) I see primary chords as "more important" than secondary, i.e., their function is clear and there's no doubts about it while the secondary have a supportive role. So, when I have two sucessive chords, one a primary chord and the other a secondary, if I need to omit one voice I tend to omit it in the secondary because the best is to keep the primary in the most stable form. Am I thinking and doing right? Thanks
