what is a fundamental movement principle of all good concert dance
Graham technique The expressive force of Graham technique had a revolutionary effect on modern dance.[28] Graham is now taught in most university dance programs, and remains the "hallmark" style of contemporary concert dance; its movement vocabulary is familiar to almost all professional contemporary dancers.[2][14] It strongly influenced several other codified techniques, notably those of Merce Cunningham, Lester Horton, and Paul Taylor.[4][5][6]
Tap dance Tap dance has its roots in the fusion of several ethnic percussive dances, including African tribal dances, English clog dancing and Irish jigs; the relative contribution of different traditions is a point of disagreement among historians and dance scholars.[1] Tap dance is believed to have begun in the mid-1800s during the rise of minstrel shows. Famous as Master Juba, William Henry Lane became one of the few black performers to join an otherwise white minstrel troupe, and is widely considered to be one of the most famous forebears of tap dance.
