From the President and the Editor

The lead article in this issue, Martin Schleske's "Eigenmodes of Vibration in the Working Process of a Violin," is the first of two papers on the subject; the next will appear in the November issue. We expect these papers to be controversial but eventually to be of great benefit to practical makers. Schleske's papers are well worth the serious study it will take to get a good grasp of their contents. Several revolutionary techniques and tuning concepts are presented here for the first time. They are
There is much to learn from the experiment reported here.

Domenicali's paper presents detailed design specifications for a "Universal Grinding Jig for Violinmakers." We are very pleased that Peter made this available to the Journal because we know from experience how useful the completed jig is. Sharp tools and thorough knowledge of traditional construction techniques and objectives are both essential if a maker is to effectively use the acoustical principles set out in the Journal's research articles. We hope that more makers will offer to share the tools, jigs, methods, and construction objectives they have found useful for producing acoustically and aesthetically superior instruments.
