Bert Matter is among the most widely influential twentieth-century musicians in The Netherlands. His works for organ have made him a highly respected composer in his country, and as a consequence Matter has had a significant impact on the Dutch organ community. Still, his works remain largely unknown outside of The Netherlands, even among the most knowledgeable performers.The compositions of Matter deserve greater attention due to their high motivic development which often combines traditional forms with modern techniques.Further, Matter has made a profound pedagogical impact on his many students, and although retired, continues to have a significant influence on those who study and perform his music.This paper seeks to shed light on this important composer through a look at his life, teaching, and compositions, with particular attention on three of his most notable works.
