Sigfrid Karg-Elerts works are attracting more attention than ever before. "Cathedral Windows" op. 106 and "Triptych" op. 141, works from the composers late creative phase are now available in new editions. The titles themselves awaken associations with Karg-Elerts extremely colorful musical language. In addition to being wonderfully suited for organ practice and teaching, the collection „Facile ma non troppo“ will also help organists discover a previously little-known side to Karg-Elert.
