A section of the documentary film Desert Fugue is about Walcha, and explains how he memorised music part by part, and passed on this method of learning counterpoint to his pupils. Selected works Recordings Works by others Walcha's opus magnum is the recording of the entire organ works by Johann Sebastian Bach, which he recorded both in mono (1947–52) and stereo (1956–71) for Archiv Produktion (a subsidiary of Deutsche Grammophon). The original mono cycle was Archiv's first release and included an improvisation by Walcha at the Organ of St. Peter and Paul in Cappel, built by Arp Schnitger in 1680; Walcha also used the Stellwagen Organ in St Jacob Church in Lübeck (built in 1636–37 by Friederich Stellwagen by extending the previous ca. 1480 organ, one of Stellwagen's most appreciated works). The stereo cycle was the first stereo recording made by Deutsche Grammophon and was reissued including Walcha's recording of The Art of Fugue, comprehensive of Walcha's own completion of the last fugue.
