Koppel Flute German/English
While Grove and Williams describe this name as a synonym for Koppel, Adlung explicitly distinguishes them, describing Coppelflöt as a Dutch synonym for the Gemshorn. According to Audsley, it is another name for a Koppel of 8' pitch. Irwin describes it as an open metal flute of 8' or 4' pitch, having a tone that is midway between those the Gemshorn and a bright cylindrical metal flute. Irwin and Maclean describe its construction as similar to that of the Spindelflöte Regarding contemporary practices, John A. Panning, Tonal Director of Dobson Pipe Organ Builders, Lake City, Iowa writes:
Generally, Koppelflöten have short cones (c. 1/4 of the body length), while Spillflöten have long cones (1/2 body length). A similar thing holds true for the diameter of the hole at the end of the cone: Koppelflöten often have smaller holes than Spillflöten, which might be 1/2 of the diameter or more. Today most Koppelflöten and Spillflöten have movable canisters (felted or papered), not flexible ears, for tuning.
