The Cheng Library has a small, but useful Reference Collection, located on the first floor of the building. While these items cannot be checked out, you may want to spend some time exploring the following resources (and others!).
Note: Recent (and ongoing) maintenance of the collection may have moved some of these items to our 2nd Floor Circulating collection, where they can be borrowed.
This (very) general diagram outlines the relative ages of different music-related subjects that you may be researching. Note that music has been around for a LONG time, and that it is likely that a lot of research has been done on music, in general.
As we get closer to modern times, though, there may be less research on the different topics, and the types of sources used will vary.
As you conduct your research, keep this in mind, as is may determine the types of databases and resources that you use to find information.
Because each of you will be approaching your research from a different angle, the following examples might be of particular use. Be sure to perform your own searches, to see what else is out there:
The new handbook of research on music teaching and learning (also as ebook)
The SAGE handbook of popular music (online)
It's also important to consider the accuracy of the information, and whether or not is has been filtered, modified, or combined with other content.
