Is there a way to change the spacing between staves (single-staff systems) in one score, in a document with multiple scores, without introducing a page break? The only way I've found in the manual to change the spacing of systems (as opposed to staves within a system) is in a \paper block, and the lowest level that can occur is in a \bookpart, which introduces a page break which I don't want. I could use NonMusicalPaperColumn.line-break-system-details, but that seems to only apply to one line, so I would need to set it separately for each line in the score, which is a nuisance.
To explain better what I need, I am re-engraving some short sections from an orchestra part, to faithfully match the lines in the original but with some particular rhythmic changes that the conductor wants. I will print these out and cut and paste them over the original (using removable/restickable adhesive), so I want everything to match the original as closely as possible. The sections range from 1 to 5 lines each. Currently I am using a separate \score for each short section, which seems to make it easier to maintain control over the line breaks. But I'm trying to fit as many on of these short scores on page as I reasonably can, to save trees. I've set the staff size and staff-staff-spacing globally to match the average in the original pretty well, but of course the spacing varies some from page to page, so some of the sections need adjustment. I could introduce a new \bookpart and \paper block for those sections, but I'd rather not have those extra page breaks. Is there a better way to do this? -David
