Resonance-wood

Resonance-wood

In January 2009 I had a discussing with Olivier Bouriaud about crossdating of a violin-type instrument: Olivier wrote:

"There are very few coniferous forests in Hungaria and the ring series are more likely to come from Romanian Carpathians (there are quite many known resonance-wood spruce sites), or maybe from Slovenia. It is common that Hungarian factories import wood from Romania. This is why I am looking at the Romanian sites, they are just much more likely. But there were also famous resonance-wood sites in Italy.."

So question from me: what is resonance-wood? - A concept I've never heard of. Got this interesting answer:

As you can guess, resonance wood is whenever a set of sometimes contradicting characteristics are present in the wood. More than one condition is needed to qualify as resonance wood - from what I know:

• large ring width (say around 5 mm),
• shallow cell walls (reduced density), and a
• radial growth with as little variations as possible. Things like this.

That should lead to a wood with a large ultrasonic velocity in fiber direction. Trees growing in high elevation are more prone to containing that so-called resonance wood. The regularity in rainfall amount during summer is a key and places Romanian Carpathian in a good position.
