Wood is the most common material for guitar construction. A few particular tree species such as Ebony, Maple, Rosewood Mahogany and Spruce have long been staples within the industry. The type chosen for a particular task is based on a combination of factors such as: availability, tonal qualities, aesthetic beauty, workability, tradition, strength, and durability.
