Harmonograph: A Visual Guide to the Mathematics of Music

Why did Pythagoras pause outside a Blacksmith’s workshop? Can the nature of Harmony really be understood visually? Why do harmonies leave gaps or ‘commas’ when added together? In this charming pocket book, Anthony Ashton uses a Victorian device called a Harmonograph to tell the story of Harmony and the intervals in the scale. With useful appendices and exquisite line drawings this is a unique and original introduction to this magical subject.
