Eleventh English

A very rare mutation stop that speaks approximately an F when played from the C key, one octave and a fourth above. It is found at 2 10/11' pitch in the manuals, where it is part of the 32' harmonic series. In the pedal it is found at 5 9/11' pitch, and is part of the 64' harmonic series.

This stop is listed only by Irwin, who incorrectly claims that it is “not a natural harmonic of any series”, and goes on to say: “It gives a dissonant effect and a close-toned brilliance to any loud Reeds or a flue combination, and also makes some clang-tone which may be brass-like in effect.”
