... I want to introduce you to a German researcher named Dieter Ennemoser. He has written an interesting book entitled:
"The Character of Sound" sub titled: 'on the discovery of the code by which the brain recognises the quality of sound'. ISBN # 3-907073-32-0 (c) 1990. The book is written in both German and English (in the same book) and seems to have some useful information that is valid for our purposes, unless I am mistaken.
{Web site : www.ennemoser.com }
... Dieter states that our brain recognises sound quality as 'good' when the sound being heard is related to the 'transient tones for carbon at 37 degrees Celsius (body temperature)'. As I understand it, he feels that sounds are transmitted through the small bones that make up our inner ear (largely made of Carbon) best at certain frequencies which carbon at body temperature transmitts more effeciently. Dieter calls these frequencies 'typical transient tones'.
...These frequencies for an octave are:,,,(In vibrations per second, HZ):
262 285 300 322 353.5 376 396.75 427 465 486 HZ (vibrations per second)
C.37.C concept for Sound Quality Considerations.

..I find the frequencies of the various parts of the violin are in the range of 198HZ to 352 HZ (As I measure them). All of the frequencies Dieter lists are above the violin range. However, if we calculate the related frequencies to the above, by dividing those C.37.C frequencies by 2, 3, 4, and 5 and listing them in order, we hae a list of related frequencies of:
<121.5,125.3,131.0,132.3,142.3,142.5,150.0,155.0,161.0,162,0,177.0,188.0,198.5,213.5,232.5,243.0>
...In fact, further research findings suggest strongly that the frequencies of 162 HZ, 176, 198, 213, 242 are on both the Wood Tone and Tap Tone scales. These are used for both tap tuning stringed instruments and wood selection for construction. Please see articles in other places on these new concepts! (2017)
..It may well be that when parts of our violin are made with these frequencies, that the sound of the instrument is more pleasing to our ears. Only careful research of excellent violins and comparing their data together will tell us of any true correlation.
...I will mention that my most successful violins do seem to have a close correlation to some of these C.37.C related frequencies.
...At another page I will list the violins,their parts and tap tone frequencies and how they compare to C.37.C related frequencies.
..How when we compare and combine these frequenices with the 'Slofeggio' frequency list, and then select those frequencies pairs that match, and list those in increasing frequency order and compare the frequencies of unusually sucessful violins; there is a close correlation. If continued research confirms this present indication, then we would have a specific acoustical plan (or choices) for making a violin that more closely matches these special violins.
