Free Music for Your Presentations

You can download free music (usually in several different lengths) for non-commercial use in your classroom from freeplaymusic:

Searching the library for music is fast and easy. You can choose a Volume Name, Style, Feeling or can perform a key word search from the main home page. You can also click the search our library button in the upper left hand navigation panel. Clicking "search our library" or "advanced search" from the home page will give you the option of customizing your search by Key Word, Feeling, Style, Instrument, Volume or Tempo.

I think it's especially nice that you can browse or search by "feeling" to get the right kind of music. Note that you (and your students) can use this in a classroom, or even for personal home videos (music to go along with movies that you create for your family and friends), for free (you do need to note the source of the music - see screen credit). You cannot use it, however, for any kind of broadcasting without paying a license fee. Broadcasting would include posting it on the web, on a blog, part of a podcast, etc.
