Scansion

You are the one;

A system for

Analyzing

And for marking

Poetical

Meters and feet

Marking short and long

Light and accented,

Syllables and thus

–          is a must

As short as a dream

As long as the Nile

Marking unstressed and stressed

Syllables so as to

Include secondary

Stress thus v/ to see

v/ and vertical

Bars to mark every feet
