IDK if its bacteria that causes it or just that the tree grew wrong
I read on a violin luthiers forum that it was also caused by extreme weather changes. A tree being treated as a crop plant in this case, it's technically a defect, but has appealing visual aesthetic qualities. However, there hasn't been concrete proof of discernible sonic properties, good or bad, introduced by it.
But the uniformity of the appearance of the spalts must point to one common factor, or at least mean that the various causes have the same effect. How does this happen?
I actually was referring to all types of figuring, and used the incorrect terminology.Yeah as Myacc said its caused by fungi and is unrelated to the other types of figuring. The other types are all related to growth and changes in cell divison for various reasons (The exact reasons are not agreed upon from what i know) At one time birdseyes were said to be the result of damage to the tree like bugs burrowing or like a wood pecker pecking a small hole but this has been proven to be untrue
