Antoine de Lhoyer [L’Hoyer] (September 6, 1768 – March 15, 1852) was a French classical guitar virtuoso and an important composer of the early Romantic period, who devoted himself primarily to chamber music for classical guitar. Lhoyer also had a remarkable military career; he was an elite member of the Gardes du Corps du Roi, Knight of the Order of St. John, and Knight of the Order of St. Louis. His music had already fallen into oblivion before his death at the age of 83 in Paris.
Musicological research has revived interest in his music, leading to several modern recordings and additions to the classical guitar repertoire (in particular, enriching the number and quality of guitar duets).
Lhoyer left behind some 40 to 50 works for the five- and six-string guitar, mainly in the form of duets, trios, and other chamber music ensembles featuring the classical guitar. Lhoyer left behind only a few solo works for guitar. The places where his works were published correspond to his travels. Opus numbers 1 to 11 have not yet been identified.
