It is most used in verses that contain meter, through a line of four trochaic feet. It is used to form a rhythm that highlights certain words.
Explanation:
The trochaic tetrometer is a meter used when a poem contains four trochees. In a poetry, the trochaic tetrometer is presented as a line of four trochaic feet, where there is the alternation of a trochee represented by a long syllable and a troche represented by a short syllable. This creates a certain musicality and rhythm in poetry, allowing some words to have greater evidence and prominence.
In "A Defence of Poetry," Shelley suggests that emotions experienced in life are constantly changing. The enthusiasm of virtue, love, patriotism, and friendship, is essentially linked with such emotions; and whilst they last, self appears as what it is, an atom to a universe.
