Classical guitar making John Schneider The basis of most "modern" classical guitar designs was developed by Spanish luthier Antonio Torres Jurado in the mid-19th century. 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.

(However, a type of fan bracing was already used before, in some guitars by the Spanish builder Joseph Páges, and after him Louis
Ten-string classical guitar of Yepes Ramírez III considered adding sympathetic strings to the classical guitar. He sought advice from the leading classical guitarists of the time, notably Andrés Segovia and Narciso Yepes, both of them players of Ramírez six-string guitars. Eventually they came up with a ten-string guitar.
