Audsley lists this stop as follows: The name that has been used to designate a covered stop of wood or metal, of 8 ft. pitch, yielding an unimitative flute-tone softer and sweeter than that of the Lieblichgedeckt, 8 ft. The stop requires, for the production of its characteristic voiced - free of any pronounced harmonic - to be voiced on wind of very low pressure, preferably 1 1/2 inches. This stop is in all essentials similar to the Stillgedeckt. Irwin also lists it: A stopped wood Flute of 8' or 4' on the manuals, resembling a very small-scale Gedeckt in structure and making a tone that is even softer than the Echo Gedeckt. The German word zart means �delicate�.
