Both the Voyager Project and Baroque Project involve research! You can use the tabs in this guide to navigate through some of the Libraries' resources that may help you provide that context during your presentations.
"Research, analyze the music and provide context you deem necessary (Who, What, Where, When, How, Why) to more greatly appreciate the piece."
Remember, not every source is useful for every type of information! For example, on the Find Articles tab, you'll see both Music Index and Grove Music Online; both are databases. But Grove Music will serve you better for background information about composers, musical styles, etc., while Music Index provides more analytical peer reviewed content. Both serve a purpose that might be useful to you, but only if you utilize them in the correct context.
