Daniel Kientzy is a French professional musician. At the age of sixteen, he began his musical career playing bass guitar in dance and rock bands before studying saxophone at the Limoges Conservatory and the Paris Conservatory. He also learned double bass at the Versailles Conservatory and performed with the Limoges Opera Orchestra, while developing an interest in early music and founding the Ensemble Musica Ficta, with which he recorded an album, performing on instruments such as crumhorn, recorder, bagpipes, and viola da gamba. In the late 1970s, he devoted himself to the saxophone and, dissatisfied with its existing repertoire and uses, undertook research that led to the publication of Les sons multiples aux saxophones, which received the SACEM Grand Prize in 1982. He later directed the “Saxophone Collection” and co-authored two books on saxophones in 1987 and 1988. In 1990, he defended his thesis Saxology, which received the SACEM Grand Prize in 2002, and he holds a doctorate in aesthetics, sciences, and technology of the arts.
