More than half of the province of Trentino is covered by forests. They purify the air, protect towns and crops, give room to biodiversity and are also important for tourism and leisure. One forest is very special, the so callled Resonant Wood, or: violin forest. Stardivarius used the precious trees from here for his famous instruments.
The Norway spruces (Latin name: Picea abies Karst) that grow here, provide a top quality resonance wood for string instruments. Due to the right mix of light, heat and humidity, their growth is slow and constant, which leads to a compact and uniform density of their trunks. That makes it an excellent transmitter of pure and harmonious sound and timbre. In Italian they are called abeti di risonanza.
In the violin forest grow ‘acoustic’ trees
The specific characteristics and uniqueness of this wood are the result of certain anatomical, physical-chemical, mechanical and acoustic properties. Resonant wood has no macroscopic defects or knots, while the fiber is straight and healthy with regular and constant growth rings.
For centuries, craftsmen know and recognize the quality. Carpenters have been knowing the secret of those trees.The legendary violin manufacturer Antonio Stradivari got his material here. And still today musicians and musical instrument makers come here to select their trees, mostly more than 200 to 250 years old.
Riping like cheese
The Magnifica Comunita’ di Fiemme, an ancient form of self government in this Trento valley, still manages a part of the forests, overseeing and controlling the certification of the wood and the management of the forest. They have a special warehouse where the split timber is resting like cheese: waiting to be ‘ripe’ to be turned into a violin, a cello or ukulele.
Trees are normally felled during the cold dormant months and by tradition, during the waning moon.
One of the guards, Giuliano Zugliani, took us on a tour.
“The trees grow high, but slow and moderate, which makes the wood dense and compact”, tells Giuliano Zugliani.
“After being cut, some of the logs are immersed in the streaming water of the nearby Trevignolo stream for several months, which adds even some more improvement to the wood.”
In the storage shed, the wood is marked with drawing pins: each colour stands for a year.
Giuliano: “The so strong, because it grows tremendously slowly. There’s also a kind of enzym that adds something special.”
Wood of water and moon
“When a piece of wood carries the letter T, it has been soaking in the Travigniolo stream, a wild water running from the mountains. After a few months, the washed wood is lighter and more flexible. It vibrates better, because it has been aged already in a way”, explains Giuliano.
“The trees are only cut on the winter solstice on December 21st, by night, because the gravity is the lowest on that moment. The lymphs are ‘quiet’, so the little juices that remain can run out more easily and the wood dries quicker. That’s why the wood is also called Moon Wood, Legno Lunare. This moon wood cutting ritual is mysterious and fascinating. It is a tradition passed down from generation to generation.”
