Virtual Choir
Whitacre's Virtual Choir projects were inspired by a video sent to him of a young girl singing one of his choral pieces.[8] He began with a test run of Sleep, then Lux Aurumque in 2009[4][9] and then Sleep again in 2010. The video for Lux Aurumque, featuring a virtual choir of 185 voices from 12 countries, was described as a "musical experience that works better than anyone might have expected."[10] It received over a million hits in the first two months of its release.
The 2010 version of the Virtual Choir 2.0 "Sleep" began in October 2010, and the video submission process was completed on 10 January 2011. Whitacre spoke at The 2011 TED Conference[11] and this video was released on April 1, 2011, accompanied with a short 2 minute example of the "Sleep" project. The YouTube release was on April 7, 2011. One year later,it had been viewed over 900,000 times.
On September 27, 2011, Eric announced on his blog his plans for a "Virtual Choir 3". On December 21, 2011, it was revealed that the piece will be "Water Night", an a cappella piece he wrote in 1995.[12] By the entry close date of February 1, 2012, 3,746 videos had been uploaded by 2,945 people in 73 countries, singing one or more parts of Water Night. NBC Network's Nightly News, and ABC National News television reported on the Virtual Choir. This heightened awareness of the project in the mainstream. The completed work was released as a YouTube video April 2, 2012, and received 100,000 views in the first week. On April 15, on the exact 100 year anniversary moment of the sinking of the Titanic, the Water Night Virtual Choir video was shown in the new Titanic Belfast commemorative building, in remembrance of those lost in the disaster.
