I have an SATB score with interludes between verses. I've built the score in a choir staff group with 4 staves for each vocal range and a 5th staff for the interlude. I'm hiding empty staves for the parts that are not singing. For example, one part is sopranos and altos so the tenor and bass parts are hidden during that verse.
The musical interlude staff is built with rests in all verses so only the music that is played during the interlude shows.
I'm trying to reduce the spacing between the staves in the interlude sections but nothing seems to be working. See the attached screenshot.
