At the same time the weight was initially kept at the bare minimum to find out in which parts of a violin mass and accompanying stiffness is needed to produce a 'good' sound. 1.2 It was the idea that starting from unconvential patterns and working with a different concept would necessarily and automatically lead to failure. Thus this would have become additional proof to the idea that the violin seen as a concept of classical makers can't be improved. While this seemed to be true at the beginning, it came clear in the continuation of various constructional experiments, that a different construction concept at least seems to be possible. 1.3 As said, it was in the first place not the goal to produce a violin with 'superior' sound characteristics but while experimenting with the violin useful hypothesis were elaborated to link constructional features with various characteristics of the sound. Princples were tested and judged by playing the instrument as well as recording sound spectra for objective comparison. 1.4 Currently this project finds itself at the turning point from being merely experimental. (Andreas Preuss, Tokyo, 2021/5/11) --------------------------------------------------------------------------------------------------------------------------------------------- 1.5 Though the original introduction of this thread has outlived itself, I believe that the general mindset is still valid. Serious violin making must not always follow already explored paths and even if there is the risk of making something foolish, there is ALWAYS the benefit of learning from unusual experiences. Everything below is the unaltered original text of this thread: 1.6 Here you can follow me constructing the super-light violin. It will be the craziest thing I ever made and please don't take it too seriously. It is the violin maker joke from my workshop. But at least I am serious enough to make it the most professional way I can imagine. So following the footprints of Antonio Stradivari everything starts with a drawing. I decided to throw over board symmetry as well and came up with the funny design below. To save weight the length is only 351mm and all distortions follow the 10 percent rule which means that one f-hole is 10 percent longer than the other.
