How to adding music in this page:
http://www.cpdl.org/wiki/index.php/Category:Sexagesima

I want to add William Byrd, Exsurge Domine : http://www.cpdl.org/wiki/index.php/Exsu ... liam_Byrd)

Thank you

Simply add

[[category:Sexagesima]] to the page, usually at the bottom. Or, one may instead add it "by mention" in the Description, with a sentence that reads something like: "This is the Introit for {{cat|Sexagesima}}." This form displays "Sexagesima" as a link to Category:Sexagesima and also categorizes the page in that category.

I will do the latter. You can see the result.
