To introduce myself quickly, I'm a young swiss violin maker, currently a student at the Swiss School of Violin Making. I’m mostly working in the construction and repair of string quartet instruments, but I'd like to open myself to new perspectives, including guitar building. I would therefore like to make a copy of a guitar built by Christoph Koch (sometimes named Cocko) and exhibited at the Musée de la Musique de Paris.
About two month ago, I sent an e-mail to the museum's department to ask them for more information about this guitar, but unfortunately, they did not reply. This is surely due to the current situation and I understand that, but I’d still like to make progress in my project. That’s why I am asking you if it is possible for you to inform me about certain aspects of its construction while you’ve worked on an instrument inspired from the Cocko’s one. I managed quite easily to reconstruct a plan of the main shape of the guitar by studying the graphical construction of the instrument (with a compass) and the soundboard is fast finish (at the moment, i’m working on the ornaments) but I'm missing some information that I'm not able to find with the help of the available photos and my knowledge in geometry. These are, among others, the depth of the soundboard, the angles of the placement of the ivory strips in the background, the geometrical placement of the parallelograms in the rose decoration, the thickness of the fillets. So I'm open to all the tracks you could give me since you've studied this guitar at length.
While waiting for an answer from you, I wish you, in these times of trouble, a good health ! Thank you so much in advance and sorry for my very very long message : )
PS : if you didn’t understand me, i’m so sorry, my first language is french.
I saw your pics, which drew my attention to you, I hope to make something from that period too but I'm gearing up to do some other projects first so it wont be till late next year before I look at anything else
thank you very much for accepting my request! I feel honored to have the opportunity to own your marvellous renaissance guitar. I know that a good instrument doesn't only sound good, but also teaches you how to play the instrument properly. There is no doubt that your guitar is of that kind. The absense of scalloped sides doesn't matter at all!
Ah but you had an unfair advantage, you knew who the subject in the photo was.
Anyways, thanks for taking the time to reply Peter, it's good to have the one that knows clear things up. I at first thought it was a cittern but decided against it because of the numbers of strings. Now I know ro look for other things as well.
