I think this question is off the back of a reference to the syncope dissonance in a post you quoted in another thread.
I looked at that because I had previously read that the syncope dissonance included both the seventh chord and the sus4, so I was wondering whether there was a time when the seventh in the V7 chord was understood to have been borrowed from a preceding ii chord (seems not).
I found a useful article at http://www.music.mcgill.ca/~caplin/capl ... ension.pdf
that explains where the term came from and a little about how it evolved.
When you talk about 16-8-16, you mean a 16 bar section followed by an 8 bar section followed by another 16 bar section? If so, then if we are going to relate this to some small-scale rhythmic phenomenon, isn't more like a skipped beat than a syncopation. It's as though 3/4 has become 5/8.
