The Voice has been a hit since it premiered on NBC in April 2011.
But if you're new to the program or just want a quick refresher course on the rules, here are some things to remember:
The show has four famous judges from all across the music industry. Artists Adam Levine and Blake Shelton return for season 4, Shakira and Usher are replace Christina Aguilera and Cee Lo Green.
The show is formatted into three stages -- blind audition, battle phase and live performance.
The blind audition kicks off the show, narrowing contestants solely by voice. Contestants are selected as the judges face the audience and are only allowed to listen. Each judge has 12 spots to fill, so this early selection process is key.
During the battle phase, the judges select two of their own to duel in front of a studio audience. The selected parties are required to sing the same song as chosen by the judge. The judges then select the winner of the face-off.
Contestants are coached by the judges during this period.
Two contestants are taken from this phase, one decided by the team's judge and one by the fans.
The final round, know as the live performance stage, involves the final eight singers left in the competition. The television audience and the coaches have an equal 50/50 share in deciding who moves on to the final four spots. From there each contestant will perform with their fate solely in the hands of television voters.
The Voice airs every Monday at 7 p.m.
