Busnois was at the Burgundian court by 1467. His first compositions there appeared immediately before the accession of Charles as Duke on 15 June, since one of his motets — "In hydraulis" — contains a dedication to Charles calling him Count. On becoming Duke of Burgundy, he quickly became known as Charles the Bold for his fierce and sometimes reckless military adventurism (which indeed led to his death in battle ten years later). But Charles loved not only war but also music, appreciating and rewarding Busnois for works composed while in his service. Busnois was listed along with Hayne van Ghizeghem and Adrien Basin as "chantre et valet de chambre" to Charles in 1467.
