What is the name of a verse form that consists of 4 metrical feet?

The name of a verse form that consists of 4 metrical feet is indeed tetrameter. In poetry, a meter is known by the number of feet it contains. Each foot typically consists of a combination of stressed and unstressed syllables. Since tetrameter specifically refers to a structure made up of four feet, it distinguishes itself from other forms such as pentameter, which contains five feet, hexameter with six, and octameter with eight. This foundational understanding of metrical feet is essential for analyzing and appreciating various poetic forms, making tetrameter a crucial concept in the study of poetry.
