My score has a few “all hands on deck” measures like the one in the attached image, but more commonly shows a subset of the full instrumentation at a given time.
If I reduce the staff size I can make that last measure look uncluttered, at the cost of making the rest of score look excessively small and spacious. Is there a better approach, where staff size can be managed to be larger when there are fewer instruments playing?
(Not arbitrarily so, since I wouldn’t want a solo line to take up an entire page. But some adjustment might be nice, whether it was automated or something I could nudge manually.)
