...How to use 'Rub Tone, and Wood Tone " methods to select a violin Bow:
...Based on my latest research and test results on violin bows; I believe that the three wood characteristic tones all come into play:
#1. The Wood Tone of the wood should be 242 HZ for both the 'stick' and the frog. If 242 HZ is not available, # 213 or # 287 will substitute with only about a 10% tonal drop.
#2. The Rub Tone of both 'stick' and frog should be '22'. If '22' is not available, then either '21' or '23' can be substituted with only about a 10% tonal loss.
#3. The Fourier Transform vertical Tap Tone all along the top and bottom surfaces of the bow stick should be 252 HZ evenly; with the side tap of the stick at 242 HZ evenly along both sides. The horizontal tap tone in the direction of the bow hair of the bow head and frog contact should be 227 1/2 HZ.
The frog vertical tap frequencies should also be at 252 HZ (including in the thumb cavity on both top and bottom ebony wood surfaces). The side tap frequencies of the frog should be 242 HZ all over.
...Unless I am mistaken, these are characteristics of the truly great bows.
..Of course other things are very important too, such as bow stiffness, balance, weight and player preferences; but these wood characteristics are fundamental...
