The 10 remaining acts battle it out to win the public's votes and stay in the competition. Today's theme is Big Band, which means the contestants must face the challenge of singing with a full orchestra. How will they get on? Judges Simon Cowell, Cheryl Cole, Dannii Minogue and Louis Walsh will be keen to support the acts they are mentoring, and host Dermot O'Leary is on hand to keep everyone going as the tension mounts.
Each X Factor judge is in charge of a different section of singers on the show. The judges do not know what section of the competition they will be in charge of until the audition process has finished. Each judge then has to pick four acts to take forward to the live section of the show. Each week the two acts with the lowest amount of public votes have to sing again in a final showdown after which the judges decide who should be eliminated. Once there are only five acts left remaining it becomes left to the public to decide who should go.
