Charles GOUNOD (1818-1893). L.A.S., Paris 20 May 1859, to the violinist Henry Vieuxtemps; 1 page in-8 on the letterhead of the City of Paris. Communal schools. Direction de l'Orphéon, address. On his adaptation of the first Prelude of Bach's Well-Tempered Clavier. "Here is the new part of Violin solo for the Meditation on Bach's Prelude. It is in G instead of C. You will see whether you prefer to play the first solo as written, or in a higher octave: in any case, I think that the passage at the end in octaves should be kept. I will see you on Monday at the rehearsal at the theatre.
