Ten-string classical guitar of Yepes

The ten string extended-range classical guitar, with fully chromatic, sympathetic string resonance was conceived in 1963[lower-alpha 1] by Narciso Yepes, and constructed by José Ramírez [III].[2] This instrument is sometimes referred to as the "modern" 10-string guitar[lower-alpha 2] (or the "Yepes guitar"[3]) to differentiate it from ten-stringed harp guitars of the 19th century.
