"BioMX Theory fo Actors" is for advanced actors and directors. If you are not familiar with the Method, perhaps, you better start with the Stanislavsky System (System of the Method). After all, Meyerhold developed his BM in reaction to the System by Stanislavsky. I use Stanislavsky's terminology (objective, obstacle, and etc.) very much the same way Meyerhold did, as a ground for his theories. Acting is seen from the Event Theory POV, which is in the book "Spectator" (dramatic action is the continuety of the events created by actors in spectator's imagination).
Address -- To whom character/actor adresses the action (line). There are several obvious addresses: 1. Public, 2. Another Character, 3. Himself, 4. God, and etc. The choice of addresses is closely linked with motivation.
Acting Areas -- Established zones of performance by an actor, according to the design of the monologue or scene with defined emotional points in space and time.
Area -- A portion of the stage for playing a scene and segments of the scene.
Acting: technology of the performance.
Action -- expressed conflict.
Actor's Text -- movement developed and performed by actor in space and time.
