This document discusses the effects of playing background music in the classroom. The author argues that background music can improve the learning environment by helping to increase memory, accelerate learning, improve reading skills, decrease stress and tension, cover up distractions, and improve test scores. However, one study found that music can interfere with short-term memory performance. The author then provides rebuttals to this counterargument, finding that certain types of background music like slow baroque music can actually speed up learning and increase memory retention. The document also discusses how music can help students concentrate by covering up classroom distractions, and how it can reduce stress levels to make students more productive.
