Most people are born with an average capacity to develop musical skills. There are always a smaller percentage of individuals who fall into the extremes of the typical Bell Curve of Distribution. At one end a minority are musically gifted—and some are extremely gifted (e.g., savants such as Mozart). At the opposite end are an equally small percentage who were born musically deficient (e.g., don’t have the capacity to learn musical skills, tone deaf).
