Thank-you William,
Your attached sample is essentially what I started with up to the point
where I wanted two movements. For that,I followed the example in section
3.2.1. It uses a "global" (not in the code sense) header for the major
title and uses a score for each of the movements. Embedded in each score
is another header block which generates an additional title markup and
allows any field, ie title, to be overridden. The paper variable
print-all-headers determines whether to print both headers. Apparently
the page headers use only the first header block that is encountered.
But as I was comparing your example and mine, it [finally] occurred to
me that it might be a scope issue and there was an intermediate option.
I had originally declared a header for the book and one for each score
in the bookparts. In the attached version, I no longer declare a header
block for the book, but instead declare one for each bookpart that
includes the "major" title and the instrument. That information is
indeed used in generating page headers as desired. And the header blocks
for the scores override the titles to show the movement names as before.
Thank-you for your help. I have attached the modified version of my
example (after paring it down a bit more like yours).

Dear Clyde,
You should be able to do this with separate \book{} or \bookpart{}
blocks. Try the example attached file. Does this achieve what you were
hoping for?
Thanks,

I would like the page header to change on the fly as data about the
composition changes. For instance, I'd like the header on the pages
for each part of a quartet to indicate the part name. The page number
changes, but info from the header field does not get changed. Is
there some means to do that? Using
\fromproperty #'header:instrument
in one of the evenHeaderMarkup fields seems like the obvious method.
The titles seem to get updated that way. But the page header doesn't
change.
