…A. de Garaude -  membre de l'Ecole royale de musique et de la chapelle du Roi

Alexis de Garaudé, * 21. March  1779 in Nancy, + 23. March 1852 in Paris;

Alexis de Garaudé  belonged to the nobility, because his father was parliament advice in Nancy. He studied music only to the completion of its education first, was spoiled by the revolution, however, and went over to music to earn cost of living. Short time later, he seriously went to Paris and took his music studies. He was a pupil of Cambini and later of Reicha (harmony and Komposition.) as well as of Crescentini and Garat (song). He got 1808 as a singer into the quay (he lost this position by the dissolution after the revolution of 1830^th). In 1816 he had been appointed teacher for Vocalisation and Solfège at the Conservatoire. He was an excellent teacher. He stayed until his retirement 1841 at the Conservatoire. In the meantime, he was promoted Prof. of a song class (1835),  member of the Comité d'enseignement (1837-1839) and to the knight of the legion of honour, an award which only seldom was granted to the artists of the time then.

Alexis de Garaudé was one of the most important representatives of the French romance;. In addition, he was a famous song teacher and unequalled master of the Solfèges. This already results from this that his Solfèges are still used and new printed today in the French music studies. Besides his actual musical activity he conducted a music publisher and tried himself  as writer and music critic. He is also author of some texts of his romances. His only opera La lyre enchantée was never performed, but it was sung by Nourrit, Mme Albert and Mlle Grassari.
The hornist Buziau was certainly consulted by Garaudé . Unfortunately, it was not possible for the editor to find further biographical facts to Buziau.
