Christmas Presents - Harmonograph
- OK, List-lovers, what goodies did you garner for Christmas? Tell us
about those awe-inspiring wonders that appeared under your tree.
Here is a book my wife gave me:
Harmonograph: A Visual Guide to the Mathematics of Music (Wooden
by Anthony Ashton
From Book News, Inc.
Economist and journalist Ashton presents graphical representations of
musical harmonies, mostly produced by the harmonograph, a simple
scientific instrument invented in the 19th century, which he
describes how to build. He explains insights that the pictures
provide into the nature and possibilities of sound combinations.

During the nineteenth century, a remarkable scientific instrument
known as a harmonograph revealed the beautiful patterns found in
music. Harmonograph is an introduction to the evolution of simple
harmonic theory, from the discoveries of Pythagoras to diatonic
tuning and equal temperament. Beautiful drawings show the octave as
triangle, the fifth as pentagram; diagrams show the principles of
harmonics, overtones, and the monochord. Anthony Ashton examines the
phenomenon of resonance in Chladni patterns, describes how to build a
harmonograph of your own, and provides tables of world tuning
systems. This inspiring book will appeal to musicians,
mathematicians, designers, and artists alike.
