Christian Debecq was born in Etterbeek on 22 March 1957.
His instrumental training was divided between several institutions: in addition to a higher diploma in saxophone with François Daneels at the Royal Conservatory of Brussels, he obtained a first prize in flute with Michel Lefèvre at the Royal Conservatory of Mons and a first prize in baroque flute with Barthold Kuijken at the Koninklijk Musiekconservatorium Brussel. He is also a laureate of the Tenuto and Live Music Now competitions. As a member of the Dinant Saxophone Quartet and the Concert Baroque, he also performs regularly as a soloist and in duo (notably with pianist Olivier Guimaud and harpist Yvette Colignon). His concert tours have already taken him to Germany, France, the Netherlands, Austria, Canada and Tunisia. After teaching at the Brussels Conservatory and in various music academies in Belgium, he now lives in the Grand Duchy of Luxembourg and is a lecturer in saxophone at the Luxembourg City Conservatory.
He writes mainly for the instruments he plays and in different styles. While some of his works (Living Cells for Reverberant Flute and Piano, D-C-D Choral Sax for Soprano Saxophone and Piano, Trio for Various Saxophones, Various Flutes and Piano) look to the avant-garde, others remain faithful to the tonal language, such as his Sonata for Flute and Piano, Sarpe for Soprano Saxophone and Harp, Piccolude for Piccolo Flute and Piano, Quentilude for Saxophone Quartet, etc. He is also responsible for several didactic pieces: Blue Dream for soprano flute or saxophone and piano, Télémania for two flutes, Impertinent Echo for horn or alto saxophone and piano, etc.
