I have some little sections of lyrics that I want to display above and
below the normal SATB staves just for occasional parts that split.
Right now they are showing up way too far away from the notes. Could
someone please explain how to fix this? I would like to be able to
tweak each piece of lyrics on an individual basis if possible. I've
tried the suggested minimumVerticalExtent = #'(-3 . 3) but this doesn't
make much of a difference and I can't figure out how to make it more
drastic. What do the -3 and 3 mean?
