The best soundtracks create their own universe that is instantly identifiable. This course is a hands-on guide to creating sonic identity. We will explore soundtracks, sonic logos, environments, compositions, and other audio-visual media in an effort to distill what makes something stand apart with a strong identity. Why do we remember the NBC logo? Is it simply repetition or are certain sounds more memorable? How does the soundtrack for Blade Runner help define the movie? We will create our own mnemonics, compositions, and scores all based on careful analysis of successful sonic worlds.
