Quadrivium: The Four Classical Liberal Arts of Number, Geometry, Music, & Cosmology by Miranda Lundy, Daud Sutton, Anthony Ashton

3.0

This could be a source text for a Dan Brown novel, full of dubious "ancient and sacred" connections. There is a lot of interesting content about how math and ratios create beauty in architecture and music that I hadn't learned about before. On the other hand, music and math theory are two areas that generally make my brain freeze over in confusion and the writing style here does not elucidate them.
