trochee

In poetry, a rhythmic unit of two syllables in which the first syllable is stressed is known as a trochee. The song "Twinkle Twinkle Little Star" is composed of trochees.

The word trochee goes back to the Greek phrase trokhaios pous, "a running foot," and this sense of motion and forward momentum translates to its literary meaning. A poem's meter — the number and type of metrical feet used in each line — determines its shape and rhythm. Since ancient times, writing that uses trochees has been thought of as more energetic and spirited than its opposite, iambic rhythm, although iambs are more common in English.
