Music has evolved over time along with people and cultures. Access to music has changed significantly with advances in technology. Learning to play a musical instrument can speed up the learning process and improve academic performance on tests, as the state superintendent of Arizona noted. Different elements of music, such as beats, notes, and time signatures, incorporate mathematical concepts. Music requires skills like determination, multitasking, and broad mental development. Countries with strong music education in schools tend to be high-performing academically. Playing music also aids creativity and can maximize learning by activating both sides of the brain. For example, Einstein credited the violin with helping develop his artistic creativity and ability to learn.
