Georges Sadeler began his musical career at the age of 8 in the Conservatory of Luxembourg City and concluded his saxophone and chamber music studies in the class of Marco Pütz in the year 2007. Besides his principal job in the Military Band of Luxembourg, he is a composer and arranger.

Already in young years, Georges Sadeler's interest in composing and arranging was aroused by his father and later by his two teachers Marco Pütz and Claude Lenners, both teachers at the Conservatory of Music of Luxembourg.

His first steps in arrangement and assignments for several Marching and Wind Bands marked the emergence of his own style, which led him to explore the vast possibilities of both contemporary and classical music. He is very interested in creating new sound colors and techniques for various line-ups.
