WOODS COMMONLY USED IN GUITAR* MAKING (*acoustic steel string and nylon string guitars)

   SOFTWOODS (*NL)

Spruces and Cedars are often used in the tops of instruments because of its high stiffness-to-weight ratio.
Sitka spruce (Picea sitchensis, also known as Alaskan spruce), Adirondack spruce (or red spruce, Picea rubens ), Engelmann spruce (Picea engelmannii) and European spruce (Picea abies, also known as Norwegian, German or Alpine spruce) are particularly valued.
Cedars, particularly Western Redcedar (Thuja plicata, not a true cedar), have since the 1950s been used in the tops of classical and steel-string guitars. Other softwoods, such as Redwood, Pine, and Fir, have been used less frequently.

   HARDWOODS (*NL)

Species that grow in Tropical areas:
Mahogany may be used in the tops of some guitars as well as the back, sides, and necks of instruments of the  guitar families. Mahogany may also be used for the solid bodies of electric guitars. Rosewoods are often used in the back and/or sides of guitars. The most sought-after variety, Brazilian Rosewood, Dalbergia nigra, has become scarce and expensive due to over-exploitation and now this species is illegal to import, export, buy, sell. Ebony is often used for fingerboards, tailpieces, bridges and so forth, but rarely as a true tonewood. 
More hardwoods: Indian Rosewood dalbergia latifolia, Cocobolo dalbergia retusa, African Utile Mahogany entandrophragma utileBrazilian Mahogany swietenia macrphyllia, African Mahogany khaya ivorensis, Koa acacia koa, Ovangkol guibourtia ehei, Black Limba terminalia superba, Blackhearted Sassafras atherosperma moschatum, Imbuya (aka Imbuia) phoebe parosa, African Satinwood distemonanthus tenthamianus, Cedrela cedrela odorata.

Species that grow in Tropical, Subtropical and Non-tropical areas:
Tasmanian Blackwood acacia melanoxylon. 

Species that grow in non-tropical areas
Maple acer pseudoplatanus and Walnutjuglans nigra (Black)/regia (French) and other fruitwoods like cherry, plum, pear, etc. are used over ages for backs and sides of the guitar family and for instrument making in general.
Basswood (also known as lime or linden), Ash and Elder are often used in solid body guitars.
Possible alternative species for acoustic instrument making: 
Beech, Birch, Ash, Chestnut, Plane, Alder, Poplar, Black Locust, Sorbus Boxwood, Oak, Yew, Laburnum....


(*NL)  Note in Dutch / Nota in het Nederlands
        De Engelse termen Hardwood (NL = Loofhout) en Softwood (NL = Naaldhout) worden soms foutief vertaald als hardhout en zachthout. Dit zorgt
        voor  verwarring. 'Hardwoods' kunnen immers zachter zijn dan 'softwoods'. Taxus (softwood) is bv. harder dan loofhoutceder, els, linden, 
        populier... allemaal 'hardwoods'.
