Spruce (picea abies)

The most common and popular among the trees used in violin making is the norway spruce also known as “spruce”. You can find it all along the Alps especially in Val di Fiemme, Paneveggio and Tarvisio. It also known as “resonance tree” for its special qualities of sound already used by luthiers since ancient times. Today , like in the past, it is used as a soundboard for all production of stringed instruments such as strings quartet, guitars, harps, pianos and even medieval instruments. The special qualities of elasticity, lightness and strength make it an essence woody perfect for such use. I would like to specify that the choice of this wood must be made especially for its sound than for the aesthetics of the same. In recent years spruce with very close and regular fiber was the favorite, almost to become a fixed fee in the choice of wood. In my experience however, soundboards less geometric, such as the second and third choice, recall a sound more harmonious and especially warmer. The instruments of the most famous ancient violin makers often have beautiful harmonic plates with no-regular fibers but with a sound so clear and full that the current trend does not like according to study a few instruments of in museums. The spruce is also called “male” because inside it has the characteristics indentations. This is just a name because in reality there isn’t a variety of male spruce. The reputation of “male” has been given by loggers because the logs that roll into the valley against other logs and stones make a baritone sound very characteristic and therefore called “male”. The sound spruce can be easily recognized because knocking at the base of the tree trunk with a mallet it makes a deep sound for about a second, that not all the trees of this species do. However, one of the notes to be highlighted is its rarity: according to a calculation of a well-known producer of soundboards in Val di Fiemme seems that only two or three trees in 1.000 are sound compared to other areas as Cadore where you can find only one tree sound in 5.000.
