I would be highlighting this cool YouTube virtual choir even if I hadn’t taken part in the project, but the fact that I sang (and am momentarily visible!) in this video makes it that much more exciting.
I would really recommend watching it in high-definition - the difference between 480p and 720p is quite dramatic. My recording is situated slightly center-right, near the top, and my close-up (as it were) is around 2:15.
Two somewhat more substantive points:
Choir music is uniquely suited to this sort of crowd-sourcing because the size of the chorus hides the imperfections of the individual members. It would be considerably more difficult to attempt a similar project with a rock song, simply because with only four or five musicians, every mistake - in tempo, in pitch, in volume - would be very evident. This point is driven home by the individual vocal tracks (many of which are still available to browse through) which - to put it politely - lack the majesty of the final product.
Through sheer chance, I first sang this song with the NYU Chamber Singers, a now sadly-defunct choir I was a member of between September 2008 and May 2009. I joined the Chamber Singers through sheer happenstance, and had I not it’s unlikely I would have ever heard of Eric Whitacre. If there are five other people who know of him in a fifty mile radius from where I am now, I’d be shocked. The internet’s power to bring together fans of niche artists (or products) is well-established, but I’m grateful for it all the same. Two months ago I stood in front of my webcam (elevated to my height by a number of hefty cookbooks) and sang into the microphone, and now I’m a member of a choir conducted by a professional composer and performing to an audience of thousands. How cool is that?
