All of the tools, the choreographic processes, and the editor’s sources
of intuitive knowledge about editing a ﬁ lm’s rhythm are used by edi-
tors in service of fulﬁ lling rhythm’s purposes in ﬁ lm. The question in
this chapter is: What are the functions of rhythm in ﬁ lm? The follow-
ing discussion suggests that the functions of rhythm are to create cycles
of tension and release and to synchronize the spectator’s physical,
emotional, and cognitive ﬂ uctuations with the rhythms of the ﬁ lm.
