66 organ pieces composed between 1906 and 1908. They were first published in 1909 and dedicated to Alexandre Guilmant. Op 65 includes the well known Nun danket alle Gott.

Karg-Elert was a German composer and teacher whose most notable influences included Carl Reinecke, Edvard Grieg, Claude Debussy, Arnold Schoenberg, and Alexander Scriabin.

His favourite instrument to compose for was the Kunstharmonium, a versatile French creation that allowed him the range of colors he preferred. From 1924 he gave weekly radio harmonium recitals from his house. To see Karg-Elert's creativity and the flexibility and range of colours offered by the Kunstharmonium have a look at Opus 101. Musical portaits of 33 composers from Palestrina to Schönberg.

I have used the Riddagshausen organ that I really like and I think it handles this music quite well. This sample seems to have slipped down the list a bit now that there are so many other organs to choose from.
