A study was presented to the 4th International Conference on Education, Economics and Humanities on September 6, 2016 that was designed to study the effects on Baroque music as an agent for relieving stress.
In the study there were sixty Iranian EFL, (English as a foreign language), students that participated in a reading comprehension test while listening to Baroque music. Then, another test called the Test Anxiety Inventory (TAI) was administered to the group.
The resulting analysis revealed that listening to the music "had a significant effect on reducing reading test anxiety".
