How to add a bass staff midway through song?
I am creating a sheet music which starts out with only one staff - treble for Vocal lead. Around measure 19, I need to add a choir part to support the lead voice, so I want to make measure 19 have 2 staves: one treble, one base. When I try to edit instrument, it adds the base staff to the ENTIRE music, but I want it only added in the measures I select. Please help me figure out how to do it. Please see attached image for how I want it to look like. Thanks.
