Many thanks to Kevin and David Kastrup -

I was able to use "non-temporary" \overrides while being explicit about the
context. That is, I used
\revert StaffGroup.SpanBar.glyph-name
while using regular \overrides, and it worked like a charm.

Thanks again,

Ralph

Reverting does not depend on whether the override happened in a \with
expression or with an explicit \override.  However, the overrides in
context definitions and \with expressions _accumulate_ on the stack
while normal \override _replaces_ the topmost override.

So if you want to get back a _previous_ context-specific value (many
grob property values are just established as global defaults and are
impervious to reverting) through reverting, you need to use
\temporary\override instead of \override.

> 2) check what the default value is in the internals manual and use
> that as a value for an override

If there _is_ a default value, reverting should get you there.

Here is an example for accumulating overrides:

\layout {
  \context {
\Staff
\override NoteHead.color = #red
\override NoteHead.color = #blue
  }
}

\fixed c'
\new Staff \with {
  \override NoteHead.color = #green
}
{
  c1
  \revert Staff.NoteHead.color
  g
  \revert Staff.NoteHead.color
  e
  \revert Staff.NoteHead.color
  c
}

Thanks, Kevin, and sorry I didn't respond earlier. It took a lot of
frustrating time for me to incorporate your changes into my original, more
complex, score.

I'm left with one small problem - the last bar line. The changes to the
SpanBar made necessary by the ossia have affected the final SpanBar, and I
can't figure out how to revert for that one bar. Any help would be greatly
appreciated.

In gratitude to Kevin and to the whole community,

Ralph

There are two ways to do this:
1) move your \override from the \with {} block into the beginning of the
music expression so that you can \revert it later on, when you need to
2) check what the default value is in the internals manual and use that as
a value for an override

In general, for tricky stuff like this I would go with 1) since it's a bit
easier to tinker with overrides and reverts while working, but since it's
quicker to do 2) in the code you sent I just did that by adding the
following override right before the last span bar:
\override StaffGroup.SpanBar.glyph-name = #ly:span-bar::calc-glyph-name
I found this value by looking up SpanBar in the internals reference and
checking the default value for glyph-name. Code is attached if this isn't
clear.

Hi Ralph,

This snippet might help:
http://www.lilypond.org/doc/v2.19/Documentation/snippets/rhythms#rhythms-changing-time-signatures-inside-a-polymetric-section-using-_005cscaledurations

I've attached my version; the only thing I wasn't able to do was get the
spacing on the ossia staves to ignore the others. I don't know how to fix
that.
