During Hollywood Week, the contestants must perform in front of the judges in hopes of advancing to the next round. These rounds consist of numerous cuts while the contestants perform in solos and in groups. Only the best contestants advanced.
While the majority of Hollywood Round is similar to that of previous seasons, for the first time ever, head-to-head duets were added.
The first judgement round of Hollywood was known as "Line of Nine". Numerous groups of contestants lined up in sets of nine to perform a song individually. After a line performed, the judges chose the best to advance on while others were cut from the competition. Those who advanced moved on to the duet rounds.
The duet rounds are the ultimate test of the stability and harmony of an artist within a duet. Like previous seasons, contestants were required to assemble into gender neutral duets of one or more. Those who failed to assemble a duet of one or more, were instantly disqualified due to the one person rule. Duets who gave a quality performance advanced on to the next round. However, duets or certain duet members that didn't perform to a good enough extent, were cut from the competition.
Those who advanced passed the Duet Rounds had to perform a solo in front of the judges. After the performances, 40 contestants were chosen to perform in front of a live audience for their Final Judgement.
After the Top 40 performed in front of their first full audience, they met with the judges for their Final Judgement. Only 20 were able to advance to the next round while the rest were unfortunately cut from the season.
