A repeating pattern of stresses, or of the presence or absence of sound, is called rhythm.
Morse code works by assigning different letters of the alphabet to different rhythms.
That there is rhythm in Hebrew poetry is denied by few, although it is difficult to discuss as the vowels in the text we have were only added at a late date, when Hebrew began to cease to be a spoken language of the Jewish community. Older poetry usually gives 2 or 3 word-units to a stich , while more recent poems may have 4 or even 5. All rights reserved.
