Beethoven's early publications have been notable for scholars because of the view that it already indicated success as a child composer. One assessment stated that "if a child composer managed only a single published item, this might not indicate much, but if they had at least two publications, this is far more significant, for it suggests that the first one had had some success." Beethoven's childhood compositions had been published until 1784. An account cited how, by age thirteen, the child prodigy was already established, having composed three sonatas and four small works in addition to the earlier work called Dressler Variations. This is significant because, at this point, he no longer needed to be taught by a tutor, who would have influenced his musical style.
