Trend Hunter first reported on this crowdsourced orchestra in December, when the competition for spots was underway.
Some of the musicians selected to participate used the Internet to rehearse before showing up for a 12-hour-a-day, three-day rehearsal process.
The competition and rehearsals culminated with a well-received performances at Carnegie Hall in New York.
Implications - The YouTube orchestra is just one of many ways the Internet has changed human and social interaction. Online rehearsals, which by choice of the musicians were equally if not more extensive and time consuming as in person practice, saves time and is more effective.
