Rehearsal : Performance :: Draft : ? Complete the analogy.

The relation is a rough first attempt made in private : the finished version meant to be seen. A rehearsal is worked through before the performance is given; a draft is scribbled before the fair copy is written out. 'Paper' is the material written on and 'Pen' the implement written with, while 'Author' is the person doing the writing — none of the three is a later stage of the same piece of work.
