Rhythm

The movement of words that creates variety of tones, strong and weak elements of a poem

Example:

I hear the sound I love, the soung of the human voice,
I hear all sounds running together, combined, fused, or following,
Sounds of the city and sounds out of the city, sounds of the day and night,
Talkative young ones to those that like them, the loud laugh of work-people at their meals...
