  1. The attached file compares in red the verso side of the original CV MS 205 scan and in black the anonymous sharing of the same form- There is a pb (always risky to use and spread unsourced info...) Forma CV strad MS 205 addieblack Original red.pdf
  2. Dear BC , actually I used a square file (and sorry for the late response)
  3. Hi Ge-off hi geoff May be that can help you , It's the math you have to follow to get the result in connection with the will of the musician
  4. Ok I understand better your idea. I agree , the human mind likes analogy as a way to get an understanding of the world unfortunately the best vegetable are not enough to make a good soup
  5. That's a bit confusing for me "A lot to do " doesn't necessarily means mean "with the quality of the sound" sonority jugements change with time and needs but not the fact that you have to divide a string in two to hear the octave. The main dimensions of the instruments was obviously and historically connected to the string length , but I don't see the connexion with a contemporary appreciation of the quality of the sound
  6. It's always the same , a lot of preliminary work to gather as much reliable information as possible before you start to think about what meaning to give to it all. I dream of collective work on these subjects, an open and collaborative database where it would be possible to deposit information. It's easy to build such collaborative database on a subject like the place of "pins" interested people?
  7. And also to compare with the other Stainer's instruments to have an idea in which direction to dig ...I mean further than "it could be connected with arching and thickness "
  8. It would be interesting to know the match between points and thicknesses in the Stainer violin
  9. - it is also the case on the friedberg instrument -If one of the goal is the check of the thickness the upper F holes on the table could play this role making the hole useless...
  10. It was the origine of my lack of enthusiasm when i wrote "need to be describe" because the thickness process mentioned doesn't explain this feature it's also why I propose these multiple finalities a clamping device could "fill a bit, the hole of the theory" What we could imagine that: - the nail help to hold the back - the nail can be a reference for the heigh of the back - the nail can be a reference for the thickness - the nail can be a reference for the soundpost (al least for the only untouched violin we know )
  11. untouched since 1594 Theses "bars" doesn't exist on the original Xray shot Yes , it's true that the fact doesn't apply to cremonese instruments. about the central pin I record 3 ideas ("theory" is may be an ambitious word for such a detail) -a central sound post -a remind of thickness process (need to be describe) -a remind of a clamping system any other ideas? PS: we have some allemanique instruments with 2 or 3 pins in the back
  12. Theories are not always opposable. I mean that we must consider that a theory can complet an other one. but actually, in this exemple it is not a theory it is a fact : on this untouched instrument of Frieberg the sound post is set on the axe
  13. Hi Mike,

    Just one info about the violin drawing ,

    is it your invention?

      Hi Francois,  I wish it was my idea but unfortunately I'm not creative enough to invent that.  I can't remember the person's name.  He posted on MN a long time ago a link to the instructions.  I printed the instructions and followed them to make the drawing.  He has a website where he sells the instructions.   I'll try to find it for you.   To be honest I think your drawing method is simpler and therefore probably more likely to be historically correct.   There is also another drawing method other than this one that uses a three bar linkage that is really interesting also. It exactly makes the C bout curves with one smooth drawing line which is really interesting when you see it for the first time.   I'll try to find a link to that one also but it's difficult to understand the instruction on that one.  

  14. hum, that makes many accidents ... If you enlarge the picture , you will notice that musical ratios has been widely used as a key element of the conception of the world. You know that music was also part of the quadrivium - Furthermore, knowing the place of the monochord in the teaching of the quadrivium, that musical instruments could have been set appart of this would be weird. Ignore this is just historically difficult to defend. Of course, I understand that the survival these ideas into what you curiously call "old traditionnal Cremonese ratios..." is difficult to grasp (may be because only a small part of the picture is spotted) Don't make of our ignorance a truth, more probably we just don't know yet how it could have been connected to the music As we say in french: " l'absence de preuve n'est pas la preuve de l'absence"
