Ann Hutchinson Guest was an American authority on dance notation and movement analysis, long based in the United Kingdom. She studied more than 80 dance notation systems and translated 20 to Labanotation. This gave her access to a number of dance works in their original version – such as Vaslav Nijinsky's L'Après-midi d'un Faune. Her extensive research, performing, and teaching career led her to establish the "Language of Dance" approach to empower educators, artists, researchers, and other professionals in their study and use of Motif notation to engage and deepen movement understanding.

Labanotation is a system for analyzing and recording human movement, invented by Austro-Hungarian choreographer and dancer Rudolf von Laban, who developed his notation on movements in the 1920s.
