Earlier guitars were often smaller bodied (though there are exceptions: Scherzer, Guadagnini, etc.). Torres created a Spanish design, with light materials supported by fan bracing. Torres' fan bracing was influential for modern classical guitars: it consists of wooden strips glued inside the body to provide support and particular deep resonance that is saturated in fundamental. (However, a type of fan bracing was already used before, in some guitars by the Spanish builder Joseph Páges, and after him Louis

The sound hole is normally a single round hole in the top of the guitar (under the strings), though some have different placement, shapes, or numbers of holes. How much air an instrument can move determines its maximum volume. The top, back and sides of a classical guitar body are very thin, so a flexible piece of wood called "kerfing" (because it is often scored, or "kerfed" so it bends with
