This document summarizes two research studies on the impact of music. The first study examined how different genres of music at various volume levels affected cognitive performance on math tests. It found that participants performed best in silence and scored higher with soft music at low volumes. The second study analyzed how rap and yoga music influenced emotions of aggression. It determined that rap music increased physical and emotional aggression more than the relaxing yoga music. Both studies demonstrated the significant impact that music can have on cognitive processing and emotional states.
