Joseph Küffner (Kueffner) (1776 - 1856) was a German musician and composer who, among other achievements, contributed significantly to the guitar repertory, including chamber music. He was a violinist with the Würzburg court orchestra, and later, when Würzburg became part of Bavaria (1802), was assigned to take charge of military music. At this point he became bandmaster with a Bavarian Army regiment. A quintet of Küffner's for clarinet and strings was once attributed to Carl Maria von Weber, and is still recorded in collections of Weber's music. He composed seven symphonies, among other works. His output also contains a substantial quantity of music for classical guitar.
