The term 'South German' in keyboard music refers geographically to the southern part of the German-speaking region, also containing parts of Austria and Switzerland – and even eastern European regions of Poland, Bohemia and Transylvania. Joseph Kelemen has been an active church musician in the South German region since 1986. He is passionately dedicated to historical performance practice and is considered in the specialist world as the authority for German organ music of the 17th century and the organ works of Johann Sebastian Bach.
