This horn recording is of a dual Leslie A200. At medium pressure, there is an audible pitch difference between the two chimes. The result is a "beating" between two similar, but not exactly equal pitches. As the pressure increased on that particular horn, one chime dropped a little lower in pitch and the two were in tune at higher pressure. The beat frequency went away which is why the louder blow has a different character.
