Graham technique is a modern dance movement style and pedagogy created by American dancer and choreographer Martha Graham (1894–1991). Graham technique has been called the "cornerstone" of American modern dance, and has been taught worldwide. It is widely regarded as the first codified modern dance technique, and strongly influenced the later techniques of Merce Cunningham, Lester Horton, and Paul Taylor. The phrase "Graham technique" was registered as a trademark before Graham's death, and was the subject of a trademark dispute in the early 2000s.
