Couples
The cast of twelve and their professional partners was announced on September 4 , 2013 on Good Morning America . All of the previously competing professional dancers returned for season 17 with the exception of Gleb Savchenko , Lindsay Arnold , and Kym Johnson ( who took the season off to be a judge in season 13 of the Australian version ) . They were replaced by Tyne Stecklein , Emma Slater , and Sasha Farber . However , Savchenko and Arnold joined Henry Byalikov and Witney Carson in the Dance Troupe replacing Julian Tocker and Oksana Dmytrenko , therefore reducing the troupe to four professional dancers .
Season seventeen of Dancing with the Stars premiered on September 16, 2013 and ended on November 26, 2013. Tom Bergeron and Brooke Burke Charvet returned as hosts and Carrie Ann Inaba, Len Goodman, and Bruno Tonioli returned as judges. The Harold Wheeler orchestra and singers also returned to provide the music throughout the season (which turned out to be their last). This was also Brooke Burke-Charvet's last season as co-host. The cast was announced on September 4, 2013, during Good Morning America. This is the first season since season one to not have a results show. Another change was the elimination of the sky-box area where host Brooke Burke-Charvet interviewed dancers after their performances. Instead, the couples were accommodated in a new seating area near the judges' table which had been shifted to the opposite side of the ballroom. A make-up room and rehearsal room were added where Charvet could chat with the couples before and after their performances. This season also introduced a new format of voting. Each week the couples will perform, and the judges will give each couple a score based on several factors, including technical execution. Since there is no results show, those scores will be added to the public votes from the previous week, and the couple with the lowest combined score from judges and viewer votes will be eliminated from the competition toward the end of that week's episode.
