Born in 1957, lives in Paris (France), cellist, one of the first to use data processing to conceive music scores, he created in 1989 the Accel company, which manufactures scores for big publishing firms, and he entirely designed and carried out the Score-on-Line music library. He wisely associated himself with a team of collaborators most qualified to respond to the objectives of Score-on-Line, and to contribute to its development in terms of quality and number of scores on offer as well as of harmony in its policy. These collaborators have been entrusted with the responsibility for the collection or the field which they develop.

Born in 1946, he graduated in piano and oboe at the Conservatoires of Nîmes and Versailles, while playing accordion for which he won a World Championship in 1968 in Pavia. He took part for several years in concerts and recordings with the Toulouse Chamber Orchestra and the Orchestre de Chambre Jean-François Paillard, and played at the Opera houses of Avignon, Aix and Marseilles. Member of the Ensemble d'Accordéons of Aix en Provence for several years, he currently teaches oboe, chamber music and theory in the south of France.
Very keen of musical data processing, he has been using this powerful tool in his teaching activities for several years.

Since the beginning of the 80s, he has been leading courses and workshops, either as main teacher or as assistant to "Serranito", Manuel "Parrillita" and Oscar Herrero (Nice, Cannes, Argelès, Arcachon, Paris...). He also writes in several magazines including "Cahiers de la Guitare", "Guitare Classique", Antwerp Standaard. He is co-author, with Oscar Herrero, of a Treatise on Flamenco Guitar (four volumes already published by Éditions Combre).
