Everyone who enters will be considered for a big, global video performance of Internet Symphony (not sure how that will be conducted), while experts from the London Symphony, Berlin Philharmonic, San Francisco Symphony, New York Philharmonic and other orchestras will narrow the field to semi-finalists. Once selected, the YouTube audience will pick their favorites and the winners will be invited to participate in a 3-day classical music camp of sorts, ending with a performance in Carnegie Hall.
