It is based on the original work of Rudolf Laban, which was developed and extended by Lisa Ullmann, Irmgard Bartenieff, Warren Lamb and others.
It is used by dancers, actors,[1] musicians and athletes; by health professionals such as physical and occupational therapists and psychotherapists;[2] and in anthropology, business consulting and leadership development.
Originally, these categories were very basic and Laban himself referred mostly to Eukinetics - which is his effort studies - and Choreutics - which is Spatial Harmony theory.
His student Irmgard Bartenieff later further elaborated these categories in four - Body, Effort, Shape and Space - and this system, known as BESS is commonly taught today.
Several subcategories of body are: Effort, or what Laban sometimes described as dynamics, is a system for understanding the more subtle characteristics about movement with respect to inner intention.
The difference between punching someone in anger and reaching for a glass is slight in terms of body organization – both rely on extension of the arm.
The eight combinations are descriptively named Float, Punch (Thrust), Glide, Slash, Dab, Wring, Flick, and Press.
The states are known as: Full effort, where all 4 motion factors are equally expressed, is usually considered to be a rare and usually momentary occurrence.
Laban described a complex system of geometry based on crystalline forms, Platonic solids, and the structure of the human body.
