Empty”placeholder” pages are sometimes useful to define the start of a new event, scene or movement in a score, or to facilitate good page turns.
To insert one or more blank pages, select the barline which precedes where you would like one or more blank pages to be inserted.
Now, choose the “Special Page Break” option from the Breaks group on the Layout tab:
(Prior to Sibelius 7 use Layout > Break > Special Page Breaks…)
Alternatively, you can use the keyboard shortcut CMND-SHIFT-RETURN (Mac) or CNTRL-SHIFT-RETURN (Windows).
This opens up to the Special Page Break dialog, where you can specify how many pages you wish to insert.
Special Page Breaks apply specifically to the current part (or score) view. If you have blank pages that you would like to appear globally in the score and parts, create the break in the score, and check “Keep Other Special Page Breaks” in Multi Part Appearance.
Note: Special Page Breaks are only available in the Full version of Sibelius (now called Sibelius Ultimate).
