Wood Tone Topic Introduction....
Maple tree growing in our back yard has some interesting tonal qualities that appear to predict both the Rub Tone and Wood Tone scale used in wooden instrument making...
  Now the wood tone scale indication( and Rub Tone) for a piece of wood is consistent through out the piece of wood; it does not change with changes of wood shape or size. It can be measured in any direction on the wood piece.
  Each part of the violin has a specific, favored wood tone. Using a near Wood Tone selection will give a approximately 5% sound quality drop for each Wood Tone step away from the ideal Wood Tone,(but might still be a good choice if the best is unavailable).
  [for instance if you used a 287 HZ or 213 HZ Wood Tone piece instead of the favored 242 HZ Wood Tone.]
 Wood Tone:
  This is a specific property to the wood that relates to sound quality. In the natural created world, there is a relationship to the tap tone of the tree trunk, the first branch off the trunk of the tree, the second branch off the trunk of the tree (also the first branch off the first branch), and the third branch off the trunk; and so on.
  When this is measured; for instance, on the maple tree in our back yard;
  Taking a tap tone reading on the trunk, first and second and third branches off the trunk gives these results: Trunk: 176 HZ; Every First branch off the trunk: 162 HZ; Every Second branch off the trunk:
144 HZ; Every Third branch off the trunk: 134 HZ; Every Fourth branch off the trunk: 129 HZ.
  Please understand this concept; the tap tone of the trunk is the same all along its length; the tap tone of each branch is the same all along its length.
[This has important implications to the selection and tuning of violin bows which also should have a consistent tap tone all along its length {{198 HZ as it turns out to be}}].
  Now this series predicts all the wood tone frequencies in the instrument making world as well as all the tap tone frequencies for all the violin families various parts; it also delineates the wood tone scale, for this superior sound wood.
  For the wood tone (and tap tone scale) scale, these special desired frequencies are:
(129 HZ, 134 HZ, 144 HZ,162 HZ 176 HZ, 198 HZ, 213 HZ, 242 HZ, 287 HZ, 324 HZ)
