lma draws from many fields including anatomy, kinesiology and psychology. it is used by dancers, actors, gymnasts and many other groups. however, it is fair to say that it is now largely replaced by video recordings. also, it is not the only kind of dance notation, and not the only way human movement can be written down as a record for later generations. and, it was not the first such system. for example, in the 1680s pierre beauchamp had a dance notation system for baroque dance, and in 1887/8 eadweard muybridge started to use film to record human and animal movement. it is film and video which has transformed our understanding of motion, rather than dance notation. but in its field the laban notation was notable.
