I'm arranging wind parts for the following song (excerpt below). This is the end of a repeated section that starts in D major and changes to F major halfway through. So, the repeat mark at the end of the section, (in the first and second time bars) sends the player back to D major. Therefore I need a cautionary D major key signature (as written in the music already).
So, how do I get these cautionary D major key signatures, using Sibelius 7, without changing the key of the following bars? Or would it just be easiest to do this with symbols in each of the parts? (Which isn't ideal…)
