These databases contain thousands of journal and magazine articles, books, chapters, dissertations, reviews, etc., about all kinds of music. Many are full text. If you find a citation for an article with no full text, search the library catalog by journal title to see if UNC owns the print version. If not, you can request an electronic or print copy using Interlibrary Loan. Searching in a general resource like Articles+ is also useful for finding articles on music.
