Do music lessons make you smarter?
Practice makes progress, if not perfection, for most things in life. Generally, practicing a skill—be it basketball, chess or the tuba—mostly makes you better at whatever it was you practiced. Even related areas do not benefit much. Doing intensive basketball drills does not usually make a person particularly good at football. Chess experts are not necessarily fabulous at math, and tuba players can’t just put down their tubas and pick up cellos.
