Debussy: Trois Nocturnes / La Mer / Images for Orchestra

Beinum was born in Arnhem, Netherlands, where he received his first violin and piano lessons at an early age. He joined the Arnhem Orchestra as a violinist in 1918. His grandfather was conductor of a military band. His father played the double bass in the local symphony orchestra, the Arnhemse Orkest (later Het Gelders Orkest). His brother Co van Beinum was a violinist, and the two brothers performed as a violin-piano duo in concerts. As a student at the Amsterdam Conservatoire, he gained conducting experience with several concerts by amateur ensembles in Schiedam and Zutphen. He also conducted concerts by the choir of the church of St. Nicholas in Amsterdam.
