You should have done some basic soundtrack work by now. Have you tried matching sound to the stock footage which you can find here? Or cleaning up the really badly recorded Gwen Harwood reading you can find here? You've also spent some time looking at a few extracts which (hopefully) show that sound can work on a number of levels; it can enhance the meaning of what you see, or it can subvert and change that meaning, or it can be wholly responsible for creating the meaning of what we see.

As such, you can go ahead and make something considerably more ambitious - something which explores the potential of sound design to construct meaning. Basically, you need to use Soundtrack Pro (or Garageband - it does more than you think!) to design a soundtrack for... something.

I suggest that you use one of the poems you have been studying in English (partly because poetry tends to offer multiple levels of meaning which can be enhanced or challenged with the soundtrack.) A couple are available as downloads at the bottom of this page. Most are available as MP3 files online. However, feel free to use another poem, song lyrics, prose, a series of pictures, a piece of film, or whatever.

Please note; I envisage this being a relatively ambitious project which reveals both conceptual (ideas) and technical (editing) skills. For those of you who are planning to go on to media or film-related courses, it could become an interesting addition to your portfolio. As such, it should probably take a few lessons.
