keiyozerifu
   The most salient characteristic of kabuki are the conventions or "movements" (kata) which make up the performative and symbolic repertoire of the kabuki stage. These conventions involve movement, dance, and voice. The voice, for instance, can be used to deliver a speech in a rythmic fashion; this is how one delivers poetic lines, for instance. Speaking poetic lines in a rhythmic fashion is called keiyozerifu, or "pattern speech." This is metrical speech; the classical meter of Japanese poetry are alternating lines of seven and five syllables. All kinds of dialogue can be delivered in keiyozerifu , and most long, declamatory speeches (tsurane) are delivered in seven-five meter. Geza music in later kabuki was added to seven-five dialogue; this type of keiyozerifu accompanied by music is called yakuharai.
