The term you are looking for could be "iambic pentameter." A line of poetry typically has a particular number of "feet" which are sets of syllables following a rhythm pattern. An iambic foot has two syllables, with the stress on the second one. Pentameter has five feet per line.
Consider the following snippet from Shakespeare's Sonnet 116:
If this be error and upon me prov'd,
I never writ, nor no man ever lov'd.
You can divide it up into feet this way (I am putting slashes between the feet):
If this / be er/ror and / upon / me prov'd,
I nev/er writ, / nor no / man e/ver lov'd.
