Resultant tones: most often just a fundamental and its fifth used to produce the octave below the fundamental. Commonly used in pedal stops on organs to produce down to 64' tones, ~ 16Hz if middle c = 256 Hz. Full length pipes for 64' are extremely rare; Sydney Town Hall and Atlantic City's Boardwalk Hall are the two best-known. Even full-length open or stopped pipes for 32' stops, ~ 32Hz, while not rare, are extremely expensive in terms of space and materials, and tones that low are more felt that heard. Most 32' Resultant stops are made with stopped pipes that produce only odd-numbered harmonics, half the length of an open pipe producing the same pitch. The effect is more pronounced and convincing in this arrangement, though with no other stops drawn it mostly sounds like the just the two pipes are sounding. Combining with other stops brings out the gravitas of the lower, resultant tone. The effect is also easier to produce with pipes made of wood rather than metal. I'm going to watch this video later, but the effect is easiest to explain by superimposing the
