Iambic meter is the rhythmic pattern of a poetic verse line composed of two-syllable units that flow from unaccented to an accented beat. The word iamb comes from the Greek iambos and Latin iambus which describe a short syllable followed by a long one. An iamb can be made up of one word with two syllables (post-accent length in words or old Shtokavian words) or two different words. Iamb is the living and rising meter: it is felt more alive because it is rising like strength and passion; it is felt more alive because it is rising like strength and passion. In Vuk Stefanović Karadžić's translation of the "New Testament" iamb makes the sentence alive and wneh tranposed into an off-beat it breathes life into music. An iambic life force is heard as sound of a heart beating and a brain. Reading hexametric or asymmetric rhyme supports cardiac synchronization because of breathing and poetic patterns that combine duple and triple syllables. Iamb can be found in speech, poetry, music, but also in the sound of the most important human organs and the sound patterns of some animal species. In some animal species (a dove) iambic sound pattern depends on breathing and the morphology of respiratory organs. While on the one hand iambic poetry is most often transposed into musical phrases that begin with an off-beat, on the other hand asymmetric iambic poetry corresponds to non-isochronous in music due to its different combinations of duple and triple syllables. Reading asymmetric iambic poetry can be used for perception, understanding and performing non-isochronous in music.&.
