Peter Brook in 'The Open Door- Thoughts on Acting and Theatre', speaks eloquently about form and structure existing in any text and about how "no true poet thinks a priori about this structure." (Brook)
And then further:
" Although he has integrated in himself certain rules, there is a very intense impulse which pushes him to make certain meanings come to life. In trying to make these elements live, he runs into the rules, and it is at that point that it integrates itself into a structure of words. Once it is printed, the form becomes a book. If we are speaking of a poet or a novelist, this will suffice. But for the theatre, one is only half way there. What is written and printed does not yet have dramatic form. If we say to ourselves: 'these words must be pronounced in a certain manner, have a certain tone or rhythm...'then, unfortunately, or maybe fortunately, we will always be mistaken. It leads to everything that is so awful in tradition, in the worst sense of the term. An infinite quantity of unexpected forms can appear from the same elements, and the human tendency to refuse the unexpected always leads to the reduction of a potential universe." ( Brook, 63-64)
