Jules DEMEUR (1814-1882). 2 autograph musical manuscripts in a collection of 6 printed scores for flute; folio, contemporary binding in green half basane with green long-grained morocco title-piece on the upper board with gilt palmettes and the name J. DEMEUR in gilt letters (worn binding). The Belgian flautist Jules Demeur taught flute at the Royal Conservatory of Brussels, where he was for a time principal flute at the Royal Opera; he married in 1847 the singer Anne Charton (1824-1892), and followed from then on the brilliant career of his wife, Mrs Charton-Demeur. He published two opuses in Brussels with Lahou, around 1840: a Fantaisie et variations pour la flûte sur des motifs favoris de La Figurante de Clapisson, and a Fantaisie pour la flûte sur des motifs de La Somnambule de Bellini. The collection includes six printed scores. Louis Drouet : Ma Fanchette est charmante, op.21 n°7 (with signatures of the editors Terry and Simon Richault), the first 3 of his Cent Études op.31, Robin Adair op.29 (flute part only) ; Jean-Louis Tulou, Concerto op.25 n°4 (flute part only) ; Charles Nicholson, A Favorite Portuguese Air ; T. Bucher, Introduction & Variations on Rossini's Air "Aurora che sorgerai" (solo flute part). The two Demeur manuscripts are the solo flute parts of two fantasies and variations for flute with orchestral accompaniment. They are untitled, but may correspond to the two opuses mentioned above. The first one (5 pages in-4, on 12 lines paper), includes an introduction and 5 variations. The second one (4 pages in-fol., on 16 lines paper) is marked " Flute Principale " ; it begins with an Adagio, followed by the Thema and 6 variations, and ends with a finale.
