This is a digital copy of the four parts of Charles Dancla's seventh string quartet, op.80 in D minor. Charles Dancla was the most prominent member of a family of musicians and a virtuoso violinist, composer and teacher. In 1828, he was admitted to the Paris Conservatory of Music, where he won the first prize in 1833. At the Conservatory, he studied violin with Paul Guérin and Pierre Baillot. Dancla played solo violin with the orchestra of the théâtre Royal de l'Opera Comique and with the Société des Concerts. In ca. 1860, he was appointed professor of violin at the Paris Conservatory and retired from that post in 1892. He wrote 14 string quartets intended for professional or amateur players (opp. 5, 7 ,18, 41, 48, 56, 80, 87, 101, 113, 125, 142, 160, and 195a) and three easy string quartets (op. 208).
