Musical composers have generally made their most significant contributions to the musical canon before they reached the age of thirty. It is commonly believed that this is the case because aging brings about a loss of cognitive ability and creative capacity. However, a study pointed out that a disproportionately large number of those composers who made their most significant contributions to the canon after the age of thirty became musicians at an older age than is generally the case. Since by the age of thirty many composers have been engaged as musicians for a decade or more, these findings suggest that the real reason why musicians over thirty rarely make significant contributions to the musical canon is not that they have aged but rather that they have spent too much time as musicians.
