Report Outline of Violin and Effect on Sound in The Pegbox Posted February 20 3 hours ago, Andreas Preuss said: I can assure you that outline as such has only a minimal effect on the sound in general. The violin didn't sound when it was completed, but I managed to get a reasonable good sound on it with some alterations EXCEPT the outline. I don't think that tracks. Controlling for a variable isn't the same as showing that variable has no effect, just that other variables have effect outside of the effect of the controlled variable. One of the better empiricists might correct me.
