To find recordings of flute music, use the Advanced Search interface in LibrarySearch. Search the name of the performer or composer as author/creator, select "Audio & Video" as the material type, and select "UO Libraries" or "Music Collection" as the search scope.
You can also search for the title of the composition. If the composition has an opus number or other type of composer number (such as BWV for Bach or K. for Mozart), search for that as the title-- this is particularly useful for searching for works with genre- or form-based titles such as concertos and sonatas, where you might get a lot of results for things you don't want if you just search the composer and title alone.
The UO Libraries subscribe to many streaming audio databases that let you listen, read liner notes, make playlists, and even clip excerpts to embed. See the Audio tab in the main Music Research Guide for a full list of our streaming audio databases; below are several audio databases relevant to jazz:
