of the Referee", whichever occurs first. If any problems with the music happens within 20 seconds after they have begun their program, the team can choose to either restart their program or to continue from the point where they have stopped performing. If they decide to continue from the point where they stopped, they are continued to be judged at that point onward, as well as their performance up to that point. If any of the mentioned problems occurs over 20 seconds after the start of their program, the team can resume their program from the point of the interruption or at the point immediately before an element, if the interruption occurred at the entrance to or during the element. The element must be deleted from the team's score and the team can repeat the deleted element when they resume their program. No deductions are made for interruptions caused by music deficiencies. The ISU provides the following definitions of musical terms used in the scoring of ice dance: Beat – "A note defining the regular recurring divisions of a piece of music." Tempo – "The speed of music in Beats or Measures per minute." Rhythm – "The regularly repeated pattern of accented and unaccented Beats which gives the music its character." Measure (Bar) – "A unit of music which is defined by the periodic recurrence of the accent. Such units are of equal number of Beats." Strong Beat – "The first Beat of the Measure or group of two Measures supporting the skating count of the Rhythm." Weak Beat – "For Rhythms with a skating count on two Measures, the first Beat of the second Measure." Clothing The clothing worn by ice dancers at all international competitions must be "modest, dignified and appropriate for athletic competition—not garish or theatrical in design". Rules about clothing tend to be more strict in ice dance; Juliet Newcomer from U.S. Figure Skating has speculated limits in the kind of costumes ice dancers chose were pushed farther during the 1990s and early 2000s than in the other disciplines, resulting in stricter rules. Clothing can, however, reflect the character of ice dancers' chosen music. Their costumes must not "give the effect of excessive nudity inappropriate for the discipline". All men must wear trousers. Female ice dancers must wear skirts. Accessories and props on the costumes of both dancers are not allowed. The decorations on costumes must
