"Learning a skill such as playing a musical instrument helps build confidence, too. If they don’t start early, students may miss out on some of the benefits of playing an instrument. Active music participation exposes students to culture, history, and traditions. It helps people to feel a part of a shared history from a young age. Music is an experience that helps connect us all together. For adults, learning to play can give a sense of accomplishment. But one of the most important reasons for learning to play music may be that great joy can be found in creating the music, as well as in just listening to a beautiful melody. Musical training has benefits that last for much longer than the actual training takes place. Enhanced thinking, memory, and confidence are important life qualities.
