Click on the "Page Layout" tab on the ribbon at the top of the screen. In the "Page Setup" menu click on the small arrow at the lower corner of that section to open a new menu.
Click on the "Margin" tab on the menu that pops up. At the drop down menu next to "Multiple Pages" choose "Book Fold." You do not want narrow margins, so take that into consideration if you reset the margins. Click "OK" to close the menu.
Type your songs in the document. Format the fonts and add graphic if you want by going to "Insert." Add additional pages, such as a title page or introduction. Have someone proof your work.
Print the book by clicking on the Office Button and then "Print." In that menu check the "Manual Duplex" box. This well tell the printer to print just one side of the pages. When printing is finished, it will prompt you to remove the printed pages and reinsert them into the printer to print the other side.
