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 little book 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. Written by Anthony Ashton.
