YouTube Symphony Orchestra asks classical and more non-conventional performers to shoot videos of them playing [Tan Dun]'s composition and a piece of standard repertoire to be judged by Google's experts and YouTube users. Sheet music for the pieces is available on YouTube in PDF form along with individualized conductor video featuring Tan conducting each part. In other words, if you're a timpanist, you can download Tan conducting the timpani part just for you. Instructions for participating are available in 17 languages in an effort to put world's classical talent on the same page, so to speak.
Google product marketing manager Timothy Lee (pictured on the right), who was involved with this idea from the start, explained to Wired.com that in addition to mashing the winning performers into a live orchestra for the Carnegie Hall performance Google will mash the uploaded performances by each winner into a single video with little boxes containing each performer, with the audio from their auditions mixed into a single orchestral track.
