    Measurements reveal the unique tonal qualities of Stradivari violins

    Geminiani surely was talking about producing a human like tone. I.e. the player should strive to produce a human like tone in the instrument. It's not the instrument per se but the player. This goes along with the misconception that the maker is the maker of sound. I say the instrument is just a tool. How many violin makers are capable to play a concert like the great soloists? How many violin makers are able to produce a human like tone by their playing?

    Violin top too thin in one spot

    Just let it be. It will be fine.

    Who do retouch thicknesses from outside ?

    An alternative is to go by the edge thickness. It ain't rocket science.

    Stradivari's secret was a concept?

    A client tell me they have better intonation on their Zethelius.
  5. No, I meant that the sound post pushes it out.
  6. Red lines are on the bass side below the f hole and the black line is the mirror imaged treble side arching. I understood it as the caving in is on the bassbar side?
  7. Andreas, as I think you know, from my way of working (inside first using a chain to find the curvature) a symmetric arch comes naturally. Also, because I'm not into copying, this question hasn't come up. Would someone find asymmetry in my archings, it would have to be from either soundpost/bassbar distorsion or unevenness in thicknesses. The asymmetry that you illustrate I imagine could only be from soundpost/bassbar distorsion. I can't see how asymmetry would be beneficial in any way.
  8. Thanks! So, is it not a matter of soundpost distorsion?
  9. The red lines are the sunken in parts? Is it not a matter of soundpost bulging/distorsion?
  10. Andreas, is there a picture to show the asymmetry? I’d like to know what you’re talking about.

    Wrong thread

    Thanks Melvin. I look forward to see the research and scans.

    And Antonio didn't know how to fix it?

    This sounds like utter non-sense. When was this study made?
