Eric Whitacre: A virtual choir 2,000 voices strong. Eric Whitacre – Composer, Conductor, Lecturer. EricWhitacresVrtlChr's Channel. YouTube Choir of 250 Fulfills Composer’s Dream. American composer and conductor Eric Whitacre spliced together nearly 250 submitted YouTube videos to form an online choir performing "Lux Arumque," and then posted the assembled piece on YouTube.
Whitacre and producer Scott Haines used social media — his blog, a Facebook page and YouTube — to assemble and audition singers for his piece. He sent the sheet music out so people could submit videos featuring them singing individual parts. He then sifted through the videos and edited the audio parts together to form a very professional-sounding choir.
