Claude Antoine Jean Georges Napoléon Coste (27 June 1805 – 14 January 1883) was a French classical guitarist and composer.

Napoléon Coste was born in Amondans (Doubs), near Besançon, France. He was first taught the guitar by his mother, an accomplished player. As a teenager he became a teacher of the instrument and appeared in three concerts in the Franche-Comté. In 1829, at the age of 24, he moved to Paris where he studied under Fernando Sor and quickly established himself as the leading French virtuoso guitarist.^[1]

Despite declining demand in Paris for guitarists during the years after he arrived, Coste achieved financial stability as a professional musician and composer. Unable to find a publisher, he had to self-publish his works. Napoléon Coste was influenced by the Early Classical-Romantic composers of the time including Hector Berlioz. Coste's Opus no.47, La Source du Lyson is inspired by nature much like Berlioz's program music.^[2]

Coste injured his left shoulder in 1863, though was able to continue public performances until 1881, two years before his death. After Sor's death, Coste edited and republished Sor's original method for guitar as Méthode complète pour la Guitare par Ferdinand Sor, rédigée et augmentée de nombreux exemples et leçons par N. Coste (translated, the title is "Complete Method for Guitar by Ferdinand Sor, Refingered and Expanded with numerous Examples and Lessons by N. Coste").

Coste was a member of the masonic lodge Les Frères Unis Inséparables.^[3]

Coste had a special fondness for playing the seven string guitar. He was famous for his unique seven string guitar with a “floating” 7th string typically tuned to D or C called the Lacôte Heptachord. Tonally this invention created more depth when played as the floating string would vibrate sympathetically even as the other strings were plucked.^[4]

He is known as one of the first composers to transcribe guitar music of the 17th century into modern musical notation. He died at age 77, leaving a significant catalogue of original compositions.
