Educationalists and methods designers realize that a good command over a foreign language depends on following supra-segmental elements consisting rhythm and intonation, which are considered as the first step towards mastering the pronunciation of a language.Among the supra-segmental elements, we focus on the rhythm. Since, it has been clear that despite having good pronunciation of sounds and consonants separately, most of Iranian learners of FFL, fail to realize the correct rhythm of the French language. In this article, we try to know why Iranian FFL learners of make little attention to the correct rhythm of French or why are they totally indifferent? In fact, our goal is to find the cause of various errors in the use of the correct rhythm among Iranian FFL learners. We realized that there is a significant relationship between age, gender and level of participants with the rhythm production and the same is true for L1 and the first foreign language (English in Iran) which are most dramatic obstacles for learning and the correct rhythm production.
