Definition: Book-matching is the process by which a plank of wood is sawn down the middle and opened up like a book, so that the resulting two pieces are near mirror images of each other. The grain pattern of a 'book-matched' soundboard should reflect this symmetry. Book-matched pieces of wood are used in the creation of higher end acoustic soundboards, so that warping and stress occurs evenly across the surface of the guitar.
Pronunciation: book·match·ing
