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]
Salsa (dance) In some styles of salsa, such as the New York style, the dancers remain mostly in front of one another (switching places), while in Latin American styles, such as Cuban style, the dancers circle around each other, sometimes in 3 points. This circular style is inspired by Cuban Son, specifically to the beat of son montuno in the 1920s. However, as it is a popular music, it is open to improvisation and thus it is continuously evolving. Modern salsa styles are associated and named to the original geographic areas that developed them. There are often devotees of each of these styles outside their home territory. Characteristics that may identify a style include: timing, basic steps, foot patterns, body movement, turns and figures, attitude, dance influences and the way that partners hold each other. The point in a musical bar music where a slightly larger step is taken (the break step) and the direction the step moves can often be used to identify a style.
