Vertical spacing

[Garrett Fitzgerald]

Evening, all. I have 4 staffs (solo and chorus) that fit nicely on one
page. I just added chord names, and blew it up so that only 3 staffs
would fit on the first page. How do I move the chord names closer to
the staff so that there's actually enough room? I tried extra-offset,
but that didn't seem to do it... Tweaking the staff-size works, but
the size it was originally at was very readable.

Thanks.
