Rhythm helps to convey a certain mood; it is a potent means of signaling heightened emotions, increased excitement, speed or slowness. Rhythmical parameters do not usually occur together in one poem. There are optional rhythmical elements, which may or may not be resorted to by the author. And there are also obligatory parameters in classical versification, without which no poem exists. Obligatory are: are final pauses, anacruses, clausulae, lines, metre, and rhyme (except for blank verse). Optional are: are framing, epiphora, stanza, syntactic parallelism, anadiplosis, etc. Rhythm is closely linked with the message of a poem. It is the latter that determines this or that choice of rhythmical elements. And it is rhythm that assists us to bring out this message. 17.
