A Dulciana stop pitched an octave lower, at 16' or 32'. Wedgwood reports that the first Double Dulciana appears to have been introduced in 1828 by Bishop at �Acre Lane, Clapham�. Bonavia-Hunt gives the scale for a metal CCC (16') pipe as 6", and for the same pipe in wood, between 7" x 6" and 6" x 4 3/4". The name Dolciano Profundo was coined by Audsley for a 32' manual stop; it is not clear whether it has ever been used in a real organ.
