Wood is generally known as a material used to build houses, furniture, cabinets, and carved figures. Aside from being a valuable material in the woodworking and furniture industry, it is also being utilized for the construction of various musical instruments such as ukuleles, acoustic guitars, electric guitars, violins, drums and many more. However, keep in mind that not all woods are suitable to be tonewoods. The type of wood a luthier will use to build a guitar is of great importance as the wood will primarily contribute to the over-all sound of a guitar. The term "tonewood" refers to any kind of wood specie that possess superb tonal properties. Each tonewood has its own unique musical qualities, some can produce a bell-like chime or a glass-like ring when struck and vibrated. Instruments are commonly made from different combination of tonewoods to achieve a particular sound, whereas other luthiers prefers to build instruments with only one tonewood of choice. The guitar or ukulele parts will depend on what kind of sound a builder is trying to produce. Usually each tonewood piece is selected because of specific acoustic and physical properties, not to mention the additional visual aesthetics it can offer. Tonewoods are categorized by softwood and hardwood. Guitar builders favored softwood for the soundboard or guitar top because of its high vibrational tendencies. On the other hand, hardwood is preferred for the guitar body because of its high density which will result to a more durable body compared to softwood.
