When played, the spruce tuning fork produces no audible ring, but rather a singular note of no duration is produced, though there is a knack to getting a sound from it. You need to hold the base of the fork firmly in one hand and bringing it close to the ear before pinching the two prongs together and releasing them in a sort of pinching manner that causes the prongs to vibrate. When played in this fashion, the sound produced is surprisingly higher in pitch than the brass fork and is closer to that of the steel and gold forks. Spruce is a type of wood produced by the coniferous tree and is thus classified as a softwood. The fibres of the wood are long and its grain is compact, straight and parallel giving it a distinctive appearance. Wood is often used as an acoustic dampener, absorbing some frequencies whilst enabling the propagation of others in the manner of an acoustic filter. Spruce does this particularly well due to its parallel bands of hard and soft matter that constitute the grain of the material. This could account for the popularity of spruce as a material for making guitars and violins, thought its superior strength to weight ratio undoubted also plays a part.
