The title of this work translates as "Kaleidoscope (Sound Surfaces for Organ)." It is constructed in the manner of some of Graap's concert works of the 1960s and 70s, using a block form wherein the music develops through the juxtaposition and return of blocks of material in contrasting affects (tempos, dynamics, and organ colors).
Lothar Graap (b. 1933) is a German composer and church musician. Educated at the conservatory in Görlitz, his primary teachers were Eberhard Wenzel and Hans Schneider. He also studied with Helmut Bornefeld and Siegfried Reda. In 1954 he began a career as a professional church musician in Niemegk, and he pursued this work at several positions until his retirement in 1998 from Cottbus, where he had been cantor at the Klosterkirche. By the time of his retirement, he had performed and directed more than 1000 vespers services and concerts in Cottbus. Graap has composed more than 700 compositions in many forms, with a particular focus on organ and choral music.
