The guitar used woods for the various parts of the instrument. The back and sides of the guitar's body are usually built with East Indian or Brazilian rosewood.
The top and back of the guitar are formed in a process known as "bookmatching," by which a single piece of wood is sliced into two sheets. The two sheets are matched to ensure continuity in the grains and glued together.
The neck, is constructed from mahogany and joins the body between the fourteenth and twelfth frets. Ideally, the fingerboard is made of ebony, Most modern guitars use strings made of some type of metal (usually steel).
