Mozart married Constanze Weber in 1782, and it is thanks to her diligent curation of ‘these marvellousrelics’ that we have these rarely heard fragments including fugues which reveal the influence of Bach anddemonstrate Mozart’s agility with sophisticated contrapuntal techniques. The more substantial Rondoshave gained popularity with their memorable themes and musical depth, while forays into Baroque stylecan be heard in the unfinished Suite. These, the improvisational Fantasias and a mocking parody of aFuneral March all highlight neglected facets of Mozart’s oeuvre.
