and negative golden sections generally articulate important structural divisions
in the piece. Note series of positive golden sections which begin
at overall work’s "negative" golden section at m. 18. The section
where the time unit changes (m. 26-38) begins at a negative golden section
point and ends at a different positive golden section point. This
is easier to look at than to write about it, so take your time and try to
understand this diagram, because what Webern does is rather ingenious.
I was not surprised to learn that the segment which begins at the negative
golden section point, is at the "deficiency," or "ausfall," which is the
structural mid-way point for the Row Structure (see Appendix #1 in my paper).
Webern’s use of retrograde in the work reflects his use of "retrograde"
golden sections. Nothing outstanding occurs at the work’s positive
golden section, by the way.
