Since the early days of the internet, musicians and technologists have theorized about online musical gaming — virtual jam sessions, online bands, etc. Latency is the killer, of course; even 100 milliseconds will render a musical performance unusable. Consequently, there has been very little activity on these fronts, even now with broadband and fast computers.

Here’s an interesting variation on this idea though. In the words of composer Eric Whiatcre, “…it occurred to me that if 100 people all recorded their respective parts (Soprano, Alto, Tenor, and Bass) we could line them all up and create a virtual choir… Singers from around the world posted their individual parts, simply singing along to the recorded piece. Scott Haines volunteered to cut it together.”
