It is well known that music affects our feelings and energy levels. We use music to create desired moods—to make us happy, to enjoy movement and dance, to energize us, to bring back powerful memories, and to help us relax and focus. Music is a powerful tool for our personal expression within our daily lives. It helps "set the mood" for the many important activities we engage in during the day. Throughout time, people have recognized and intentionally used the powerful effects of music to their advantage. The scientific community has conducted research to validate and expand our analytical knowledge of music. This research supports what we know from personal experience: Music greatly affects and enhances our daily living activities and learning performance.
