Leo DELIBES (1836-1891). 3 L.A.S.; 6 pages in-8 or in-12 (photograph attached). Friday [1864], to Henri d'Erville (author of the prologue in verse to Delibes' La Tradition). "Certainly I accept! [...] I will hardly be able to enter your domain until about 6 o'clock, after the cantata, the opera performance, and my Vespers. [...] The hundred voices of fame must have told you that I was in Baden a fortnight ago"... Wednesday 16 January [1878], to the baritone Léonce Valdec. "You can announce for the programme of the Cressonnois concert of the 27th, my melody entitled Regrets which I am very happy to know is in your repertoire. Between now and the end of the week I will take care of the instrumentation and I will send it in due course [...] I would ask you to tell me if the orchestra is numerous as a quartet, and if you think that the piece needs to be a little sustained, or on the contrary accompanied very lightly. [...] there will be an indispensable harp score"... Sunday, to a lady, concerning her contribution to his "precious album"...
