The Very Low Notes

"Bourdons speak quickly if voiced properly and can be used under almost anything."
by Allan Carrick 

"Resultants? The best work excellently. And if course you don't just have to use 10 2/3 against 16 foot to make a 32 foot. The more mutations you use the stronger the false fundamental becomes, but at the same time the more like a reed than a flue the tone becomes, in the broadest sense."
"The soft stopped rank has the peculiar effect of picking up power from whatever is playing above it, and still tells in full organ. Very versatile. One of the best I know is at La Trinite in Paris (CC 1868 I think, or maybe 1872...)"
by Peter Rickinson
