is metrically strong, and a short syllable with a main stress is metrically weak. All syllables without a main stress are metrically neutral. A strong syllable can only occur in the rising part of the second, third, and fourth foot of a line: A weak syllable can only occur in the falling part of these feet: Neutral syllables can occur at any position. The first foot has a freer structure, allowing strong syllables in a falling position and weak syllables in a rising position: It is also possible for the first foot to contain three or even four syllables. There are two main types of line: a normal trochaic tetrameter and a broken trochaic tetrameter. In a normal tetrameter, word-stresses and foot-stresses match, and there is a caesura between the second and third feet: A broken tetrameter (Finnish murrelmasäe) has at least one stressed syllable in a falling position. There is usually no caesura: Traditional poetry in the Kalevala meter uses both types with approximately the same frequency. The alteration of normal and broken tetrameters is a characteristic difference between the Kalevala meter and other forms of trochaic tetrameter. References Types of verses
