The 1794 first edition had these gaps filled in, and most Mozart scholars such as Alfred Einstein and Alan Tyson have assumed that the additions were made by the publisher Johann André. Einstein is on record as finding André's completion somewhat wanting: "For the most part, this version is extremely simple and not too offensive, but at times—for example, in the accompaniment of the Larghetto theme—it is very clumsy, and the whole solo part would gain infinitely by revision and refinement in Mozart's own style."
