{"value"=>"<p>The Movement Files consist of the final work of the Gurdjieff Heritage Society in compiling what they felt was the most accurate material relating to each Movement. Each file holds reproductions of original choreographic notes, sheet music, and photographs when available. The extent of material varies by piece. Some Movements are not represented in this sub-series, though they may be represented in the Movement Research Files. This is a result of absent or incomplete authentic material available to the Society. Material was deemed to be authentic if the notes had been vetted by Jessmin Howarth, Jeanne de Salzmann, and Marthe de Gagnion. Movements lacking authenticated material are marked \"No Material\" and are listed for the sake of continuity.</p> <p>The Movements are classified with one of four designations: Early Movements, \"The Thirty-Nine,\" Other Movements, and Preparatory Exercises.</p> <p>\"The Thirty-Nine\" are forty-six Movements which Gurdjieff created and authorized as complete in the last years of his life. They consist of thirty-nine Movements finalized in France and another seven added in New York. The Movements are known by their American and French numbers, as well as occasionally by an informal name. The American number is the Movement's official title and the order in which they are to be executed. These Movements are arranged in two runs – the first being a set of notes approved by Jessmin Howarth and Jeanne de Salzmann, and a second with notes photocopied from other sources, music, and occasionally photographs. This second run is meant to supplement the first.</p> <p>Early Movements include the repertory created during the years 1917 to 1924 culminating in public demonstrations in Paris in 1923, and the United States in 1924. These consist of the Obligatories, Dervishes, work dances, and various round and women's dances, and are arranged alphabetically by title or dance type.</p> <p>Other Movements include pieces which were worked on but left incomplete by Gurdjieff dated from 1939 to 1949. These Movements are titled, but unnumbered, and include Multiplication, Medical Gymnastic, and Five Prayers, among others. A portion of these were later used in Jeanne de Salzmann's Movement Films.</p> <p>De Salzmann and other pupils created many \"preparatory exercises\" for teaching Movement concepts throughout the years. These exercises were designed to prepare students for Movements and The Work but were not created by Gurdjieff. Examples include Father-I and Om-Im-Am-Um.</p>"}
