FD scores. Discontinued segments Compulsory dance Before 2010, the compulsory dance (CD) was the first segment performed in ice dance competitions. The teams performed the same pattern around two circuits of the rink, one team after another, using the same step sequences and the same standardized tempo chosen by the ISU before the beginning of each season. The CD has been compared with compulsory figures; competitors were "judged for their mastery of fundamental elements". Early in ice dance history, the CD contributed 60% of the total score. The 2010 World Championships was the last event to include a CD (the Golden Waltz); Federica Faiella and Massimo Scali from Italy were the last ice dance team to perform a CD in international competition. Original dance The OD was first added to ice dance competitions in 1967. It was called the "original set pattern dance" until 1990, when it became known simply as the "original dance". The OD remained the second competition segment (sandwiched between the CD and the free dance) until the end of the 2009–2010 season. Ice dancers were able to create their own routines, but they had to use a set rhythm and type of music which, like the compulsory dances, changed every season and was selected by the ISU in advance. The timing and interpretation of the rhythm were considered to be the most important aspects of the routine, and were worth the highest proportion of the OD score. The routine had a two-minute time limit and the OD accounted for 30% of the overall competition score. Canadian ice dancers Tessa Virtue and Scott Moir hold the highest OD score of 70.27 points, achieved at the 2010 World Championships. Competition elements The ISU announces the list of required elements in the rhythm dance and free dance , and each element's specific requirements, each year. The following elements may be included: the dance lift, the dance spin, the step sequence, turn sequences (which include twizzles and one-foot turn sequences), and choreographic elements. Dance lift: "a movement in which one of the partners is elevated with active and/or passive assistance of the other partner to any permitted height, sustained there and set down on the ice". The ISU permits any rotation, position, and changes of position during a dance lift. Dance lifts are delineated from pair lifts to ensure that ice dance and pair skating remain separate disciplines.
