"A Short Organum for the Theatre" ("Kleines Organon für das Theater") is a theoretical work by the twentieth-century German theatre practitioner Bertolt Brecht.[1] It was written while in Switzerland in 1948 and published in 1949.[2] In a diary note from the time he refers to it as a "short condensation of the 'Messingkauf'"; when it was re-published in 1953 he identified it as a "description of a theatre of the scientific age"; later still he augmented it with some appendices and linked it to his notes for a "dialectical theatre".[2]
