Throughout its history the violin has had a mystique with many curious beliefs. Physicists have now discovered how it produces its sound, though this knowledge is largely inaccessible to makers and players. This book explains how strings vibrate and the roles of the bow, bridge and body, glue and varnish, without assuming the reader has any scientific background. But physical sound is a poor indicator of the sensations it produces, and the core of the book explains how that sound relates to the sensations we hear. This leads to the conclusion that most of the myths are groundless, but also that nothing can be achieved by applying any modern technology to making or playing; indeed, it would be a disaster if that happened. Practical advice on strings, maintenance, purchase, and children's instruments conclude the discussion.
