Labanotation and Kinetography Laban evolved separately in the 1930s through 1950s, Labanotation in the United States and England, and Kinetography in Germany and other European countries. As a result of their different evolutionary paths, Kinetography Laban hasn't changed significantly since inception, whereas Labanotation evolved over time to meet new needs. For example, at the behest of members of the Dance Notation Bureau, the Labanotation system was expanded to allow it to convey the motivation or meaning behind movements. Kinetography Laban practitioners, on the other hand, tend to work within the constraints of the existing notation system, using spatial description alone to describe movement.
