I'm writing jazz charts in Real Book style using Notion. I want to have a piano staff for the first line, to write the intro and establish the rhythm / style / bass pattern, then have just the treble clef only from there on. I can't seem to find a way to do it, I tried 'change staff settings within the score' from the manual but it just changed the whole staff. I want the first line different to the others .... must be doable??
