Musurgia Universalis, sive Ars Magna Consoni et Dissoni ("The Universal Musical Art, of the Great Art of Consonance and Dissonance") is a 1650 work by the Jesuit scholar Athanasius Kircher. It was printed in Rome by Ludovico Grignani and dedicated to Archduke Leopold Wilhelm of Austria. It was a compendium of ancient and contemporary thinking about music, its production and its effects. It explored, in particular, the relationship between the mathematical properties of music (e.g. harmony and dissonance) with health and rhetoric.
