Skills involving sound, visual patterns, mathematics, language, emotional expression, movement and creative planning – they are all needed in learning, playing, performing or creating music.
Research shows that music positively affects the brain by releasing pleasure-inducing neurochemicals like dopamine, improving mood, and enhancing memory and cognitive function. It also stimulates various brain regions, strengthening connections and increasing neuroplasticity, which helps with learning, creativity, and even the management of pain and stress.
