'The Voice' began their finale week on Monday, Dec. 17 with a touching musical moment that paid tribute to the 20 children and six adults tragically slain during the Sandy Hook Elementary School shooting on Dec. 14.

The show opened with Christina Aguilera, >Adam Levine, Blake Shelton, and Cee Lo Green, along with host Carson Daly and their social media host Christina Milian and a majority of this season’s finalists on stage surrounded by candles. They each were holding a card with the name and age of a victim, while they performed Leonard Cohen‘s beautiful song 'Hallelujah.'
