There is a workaround to this. It's a bit of a *** but does work! Here we go:
1 - Open up your music score in GB
2 - Click on the file menu and then click on Print
3 - In the print dialog box, click on the arrow next to PDF - bottom left-hand corner of dialog box
4 - Click on Save as PDF
5 - Name the file and save it to your desktop, then close GB
6 - On your desktop, open up your PDF file in Preview
7 - In Preview, save as a JPG file to your desktop.
8 - Open Pages
9 - Drag you saved JPEG file from your desktop into the Pages window and resize it to fill your page
10-Open up a text box onto your score in Pages
11-Resize the text box so that it fits under your top line of music
12- In your Pages Edit menu, save your text box
13- Now you can copy text boxes under all your lines of music
14- Finally, write your lyrics in the text boxes.
I told you it was a ***!
Happy lyric writing
