Foreign language classroom anxiety (FLCA) has been the subject of several studies aimed to optimize learning of a foreign language in the classroom. However, few studies provide specific curriculum-based methodological strategies to be used in the classroom in order to lower the anxiety level. In this article, two experimental classes of 8th-grade students participated in a 5-week intervention program aimed to teach French as a foreign language through music during the regular French classes. One class had a higher anxiety average (ExpHi) compared with the other (ExpLo). The self-reported level of anxiety of the two experimental classes was compared after the intervention program with the self-reported level of anxiety of two control classes with similar levels of anxiety (CtrHi and CtrLo). The study also compared the opinions of students from the experimental classes regarding their overall experience of the foreign language classes. Findings indicated that teaching songs during FL classes was perceived as an enjoyable experience by students from classes with both high and low anxiety; however, this teaching method decreased the FLCA average of classes of students with rather high anxiety, but not of the ones with a rather low anxiety.
