Classical guitar music is the notated, concert tradition for the six‑string, nylon‑strung (formerly gut‑strung) guitar, performed with the fingers rather than a plectrum.
It emphasizes polyphony and idiomatic resonance: independent voices, arpeggiated textures, campanella (bell‑like) fingerings, and coloristic right‑hand placement (tasto/ponticello). Repertoire spans transcriptions of Renaissance and Baroque lute/vihuela works, original pieces from the Classical and Romantic eras, and a rich 20th‑ and 21st‑century corpus shaped by Iberian and Latin American composers. While primarily a solo art, it also includes chamber music and concerti, and has deeply informed modern acoustic technique well beyond the concert hall.
The classical guitar lineage begins with plucked‑string predecessors: the Renaissance vihuela and the Baroque five‑course guitar, alongside the parallel but larger lute tradition. By the late 18th and early 19th centuries, the modern six‑single‑string Spanish guitar became standard, enabling idiomatic polyphony and a stable concert instrument.
Composers‑performers such as Fernando Sor, Mauro Giuliani, and Dionisio Aguado codified technique (rest/free stroke, legato slurs, arpeggiation) and built a substantial, formally Classical and early Romantic repertoire. Their études and sonatas established the guitar’s credibility as a chamber and solo instrument across Europe.
Francisco Tárrega refined right‑hand nail technique and a singing, legato aesthetic; his miniatures and transcriptions drew the piano and lute repertories into the guitar’s orbit. In the 20th century, a global revival emerged: composers like Heitor Villa‑Lobos, Manuel Ponce, Joaquín Rodrigo, Benjamin Britten, and Leo Brouwer expanded harmonic language, form, and orchestral collaborations, while virtuosi elevated concert standards and pedagogy.
Post‑mid‑century, the repertoire diversified through Latin American idioms, Spanish folk dance influences, and modernist/neo‑tonal currents. Guitar ensembles (duos, quartets) flourished, new works explore extended techniques, scordature, and electronics, and historically informed performance reconnects with early plucked traditions. Today the classical guitar is a truly international concert instrument with vibrant commissioning and competition circuits.
