The Mathematics and the Liberal Arts pages are intended to be a resource for student research projects and for teachers interested in using the history of mathematics in their courses. Many pages focus on ethnomathematics and in the connections between mathematics and other disciplines. The notes in these pages are intended as much to evoke ideas as to indicate what the books and articles are about. They are not intended as reviews. However, some items have been reviewed in Mathematical Reviews, published by The American Mathematical Society. When the mathematical review (MR) number and reviewer are known to the author of these pages, they are given as part of the bibliographic citation. Subscribing institutions can access the more recent MR reviews online through MathSciNet.
Evans, Brian. Number and form and content: a composer's path of inquiry. The Visual Mind, 113--120, Leonardo Book Series, MIT Press, Cambridge, Mass., 1993.
The author shows how the golden ratio occurs in music and art. His examples include Mozart's Symphony in G Minor, Grant Wood's American Gothic, Piet Mondrian's Composition with Blue, and some of his own musical and visual compositions. More controversial examples include the Great Pyramid in Egypt and Stonehenge, where the author shows how approximate values of both pi and the golden ratio can be found. The author mentions Luca Pacioli's statements on the golden ratio in De Divina Proportione and discusses other aspects of the philosophy of number and art as well.

Discusses number symbolism in the works of Mozart and Beethoven. With Mozart, discusses in particular Die Zauberflöte and the last three symphonies (and particularly the Symphony in g of 1788). There is also some evidence that Mozart used gematria. Literary sources also attest to Mozart's interest in numerology. With Beethoven, focuses primarily on Piano Sonata op. 111 (no. 32), the Diabelli Variations, and the Missa Solemnis. The choice of opus numbers themselves appear to show an interest in numerology. The author suggests that some knowledge of the history and conventions of numerology would be useful before reading this article. The author's own article in the Companion Encyclopedia of the History and Philosophy of the Mathematical Sciences may be useful in this regard. The author also suggests some avenues for future research. Closely related topics: Music, Numerology, Gematria, and Beethoven.
