In addition to more formal reform measures, Peking-opera troupes during the 1980s also adopted more unofficial changes. Some of those seen in traditional works have been called "technique for technique's sake". This has included the use of extended high pitch sequences by female Dan, and the addition of lengthier movement sections and percussion sequences to traditional works. Such changes have generally met with disdain from Peking-opera performers, who see them as ploys to gain immediate audience appeal. Plays with repetitive sequences have also been shortened to hold audience interest. New works have naturally experienced a greater freedom to experiment. Regional, popular, and foreign techniques have been adopted, including Western style makeup and beards and new face paint designs for Jing characters. The spirit of reform continued during the 1990s. To survive in an increasingly open market, troupes like the Shanghai Peking Opera Company needed to bring traditional Peking opera to new audiences. To do this, they have offered an increasing number of free performances in public areas.
